------------------------ RELEASE 1.3.2 ------------------------
Bugfix release. This fixes a few problems in 1.3.1
* Sound system won't initialize properly under linux: Fixed.
* Panda DLL names now all start with "libp3" or "libpanda"
* Normals reversed in heightfield tesselator: fixed.
------------------------ RELEASE 1.3.1 ------------------------
Bugfix release. This fixes a few problems in 1.3.0
* Sound system won't initialize properly under linux: Fixed.(Update: Not fixed)
* Panda not compatible with SElinux: mostly fixed, except fmod.
* Max exporter and importer broken: Fixed.
* Minor problem involving gsg handling in showbase: Fixed.
------------------------ RELEASE 1.3.0 ------------------------
This release contains several new features, and as such, it might be
buggy. However, we've been testing it internally for a couple weeks,
and it seems to be okay. It contains the following new features:
* Stencil buffers and stencil operations now supported.
* Sound API now supports DSP and better support for large MP3s.
* Video uses FFMPEG instead of DirectShow - no more codec issues.
* Heightfield terrain.
* Support for intra-frame animation interpolation.

* Various minor improvements to the particle system.
* Scene editor at least partially operational (alpha level)
* Removed most of the 65,536 vertex-per-mesh limits.
* Various low-level optimizations.
* Support for threaded model loads (only in CVS, not in distro).
* Support for 'model-cache-dir', which caches a BAM each time you load an EGG.
* OnscreenText/DirectLabel can contain embedded 3D models inside the text.
------------------------ RELEASE 1.2.3 ------------------------
The last release was a disaster:
* I failed to fix packpanda.
* I broke the tcl/tk stuff.
* I added ppythonw, and it wasn't reliable.
So basically, this release fixes packpanda and tcl/tk. It doesn't
fix ppythonw yet (I don't know what's wrong), but it does disable
it temporarily. It keeps the few things from 1.2.2 that were worth
keeping.
------------------------ RELEASE 1.2.2 ------------------------
This is a minor bugfix release.
* Adds 'ppythonw', a version of ppython that doesn't
open a console window.
* If you have a bad fmod DLL in your windows folder,
this version compensates.
* Fixes a small bug in the VRML-to-egg converter.
* Small stylistic improvements in some sample programs.
------------------------ RELEASE 1.2.1 ------------------------
This release is likely to be much more stable than its predecessors.
It contains many new features:
* lots of performance optimizations
* a preliminary OSX port
* new modes for animation blending
* easier partial-body animations
* more powerful shader-to-engine interface
* better support for rotating bodies in physics engine
* support for compressed model files
* multiple render targets (ie, glDrawBuffers)
* support for stereo rendering
* more complete API reference manual
* ability to control mipmaps explicitly
* better tools for debugging offscreen buffers
* new sample programs
* a number of packpanda repairs
------------------------ RELEASE 1.1.0 ------------------------
This is a BETA release. It's pretty reliable, but there are still a
few quirks here and there. Over the summer, Panda3D was overhauled
top to bottom. The new code is dramatically improved, but it needs a
little bit of testing. The new features are:
* Much faster rendering of high-poly models.
* Dramatically improved vertex and pixel shader support.
* New demo programs using shaders and render-to-texture.
* Play movies by using an AVI as a texture (windows only).
* Python scripting uses much faster python to C++ interface.
* Support for procedurally-created geometry (eg, fractals, etc).
* Cleaner, simpler internal data structures.
* Comes with Python 2.4 support built-in.
* A lot more.
The new demo programs are:
* Render to Texture Demo
* Cartoon Shader Demo
* Motion Trails Demo
* Procedural Geometry (Fractals) Demo
* Normal Mapping Demo
However, a caution: this is a BETA release: reasonably stable, but
not quite perfect. Please send us your bug reports.
------------------------ RELEASE 1.0.5 ------------------------
UPDATE: this release broke support for visual studio. Use
panda3d 1.0.4 if you wish to compile panda from scratch using
visual studio.
This release consists mainly of compatibility improvements.
* Now compiles under MS Visual Toolkit (makefile changes)
* Now compiles under Mandrake 10.1 (a fix in the makefile)
* Now compiles under Debian Sarge (a fix in the VRML lexer)
* Now compiles under Ubuntu HH (same as DEBIAN SARGE)
* Add code for building debian 'deb' archives.
* Fix scene editor and particle panel so they work on linux.
* Add support for --no-python to makepanda.
* Tidied up makepanda a bit.
------------------------ RELEASE 1.0.4 ------------------------
* This version includes the new Max exporter and the new Maya
export panel.
* We have added the --genman option to makepanda (to
regenerate the API reference manual). This uses the epydoc
documentation-generation system.
* Several bugs in the new tutorials have been repaired.
* A bug in fmod positional audio has been fixed.
* Makepanda now puts the maya and max plugins in a
separate 'plugins' directory, for convenience.
* The 'libpandaegg' library has been exported to python.
------------------------ RELEASE 1.0.3 ------------------------
* The binary release contains a brand new collection of
sample programs. The new sample programs are much better.
* If you install the windows binary release, the
sample programs can now be run from the start menu.
* Lighting under DirectX was broken. This has been repaired.
* The binary release has been compiled with support for pstats.
(Previously, it was compiled with pstats disabled).
* Various changes to make panda3d more compatible with
the 'epydoc' documentation-generation system.
------------------------ RELEASE 1.0.2 ------------------------
This is a bugfix release.
* makepanda contained a bug: it was compiling maya2egg6
against the Maya 5.0 libraries, making it largely useless.
This is fixed.
* Maya2egg65 has been added, for Maya 6.5 users.
* The configuration combo "want-tk=false, want-directtools=true"
used to confuse panda, because directtools uses Tk. Now
it's smart enough to do the right thing.
* When you ask controlJoint to create a control node for
you, it initializes the control node to the joint's initial
position.
* The scene editor supposedly works now. We'll see.
* The models directory was missing the animation 'panda-walk4',
which is necessary for the tutorial.
* A new directory 'win-extras' has been added to the
thirdparty tree. This contains some miscellaneous python
libraries needed at the Entertainment Technology Center.
The script that builds the windows installer will include
these libraries in the distribution.
------------------------ RELEASE 1.0.1 ------------------------
This is a bugfix release.
* In the previous binary release, Config.prc did not contain a
load-display line. This confuses pview. Pview is being fixed,
but until then, the load-display line has been restored.
* The Max and Maya plugins were inadvertently omitted from the
previous binary release. This has been corrected.
* An error in the distributed object networking layer has
been fixed. The error only affected those who were trying to
write LAN games using the CMU LAN server and p2p messages.
* An error in the physics code has been corrected.
* Python Megawidgets (pmw), which is required for "directtools",
was not supplied in the previous release. We are now including
pmw. In the Linux RPMs, to avoid overwriting any
distribution-supplied pmw package, we put this package
into /usr/share/panda3d.
* To be consistent, we moved all the other python code into
/usr/share/panda3d as well. This requires a file 'panda.pth'
in the python lib directory.
* In the binary RPMs, the file permissions of the python
source files have been changed to 555, so that even if root
runs panda, the '.pyc' files will not be modified or regenerated.
------------------------ RELEASE 1.0.0 ------------------------
Configuration, installation, and execution environments:
* This is the introduction of the new Panda version numbering
system. The Panda version will be represented with three
dot-separated numbers. The first number, the major version, will
change only very rarely. The second number, the minor version,
will increment frequently, with each new feature release. The
third number will increment as needed to indicate bugfix releases
on the minor version.
* Use PandaSystem::get_version_string() (or
PandaSystem.getVersionString() in Python) to return the version
number of the currently-running Panda.
* New runtime config system allows for dynamic loading of prc files
and supports querying of available variable names. Use
ConfigVariableString, ConfigVariableBool, etc. to get a value from
the prc file(s); use the ConfigVariableManager and
ConfigPageManager classes (or the cvMgr and cpMgr global objects
in Python) to make general queries.
* The ppremake build system now properly detects intra-tree
dependencies, but only if each tree is fully built and installed
before ppremake is run within the next dependent tree. Requires
using ppremake version 1.18 or higher.
Miscellaneous:
* New support for encrypted streams, including encrypted subfiles
within a multifile, using the OpenSSL encryption library. Adds
pencrypt and pdecrypt programs.
* The default port for PStats is now 5185, to avoid a conflict with
Instant Messenger.
* New "smooth" checkbox on PStats graphs provides a better sense of
overall trends when graphs are noisy.
* The meaning of the three components of HPR angles has been
officially changed, in particular the meaning of the R component.
This change was introduced to make the three components more
consistent with each other, and to make P and R work together in a
more sensible way. Existing code which used hard-coded HPR angles
may be invalidated by this change. To convert existing code, you
should use the global function old_to_new_hpr() to determine what
new HPR triple that corresponds to an old HPR triple. As a
temporary stopgap, you may define temp-hpr-fix 0 in your prc file.
* Add support for weak reference counts using the WeakPointerTo
class.
* Add optional support for STL's semistandard hashing containers,
e.g. hash_map and hash_set.
* Panda no longer requires any registry keys or environment
variables. This means it is now possible to run panda directly
from a CD, install multiple copies of panda on a single machine,
or install panda by copying the tree from another computer.
Note that the installer does add the panda 'bin' directory to
your PATH, and it does store an uninstall key in the registry,
but neither of these is needed for panda to function.
* The 'makepanda' build system is now capable of building
prepackaged games for Windows. These prepackaged games are simply
copies of panda with the game code included, some of the
unnecessary stuff stripped out, and some changes to the start
menu. See "Airblade - Installer" on the panda downloads page
for an example.
* This is the first release to include not just a binary installer
for windows, but also binary RPMs for fedora 2, fedora 3, and
redhat 9.
* All of the sample programs have been tested. The ones that didn't
work have been removed, the ones that do work have been (lightly)
documented.
* In the Win32 binary release, the 'config.prc' file has been moved
to the 'etc' directory. This is to make it consistent with the
Linux version.
Rendering system:
* Multitexture support is now part of Panda. This introduces the
TextureStage and TexCoordName classes, as well as new interfaces
like NodePath::add_texture(). As of the present release,
multitexture is only supported when using the OpenGL renderer.
* Support for programmable shaders is now possible using the Cg
shader language. Assign a CgShaderAttrib to a node to apply a
programmable shader.
* New support for the Helix library allows playing of a streaming
movie in a Panda texture. Presently only supported on Windows.
* Deprecated the old "win-origin-x" and "win-origin-y" prc variables
in favor of "win-origin", which takes two numbers separated by a
space. Similarly with "win-width" and "win-height", in favor of
"win-size".
* Deprecated the old Camera::set_scene() interface; now a Camera
implicitly renders whatever scene graph it is parented to.
* Removed the old GraphicsLayer and GraphicsChannel classes.
Instead of using these interfaces, you can now create any number
of DisplayRegions directly on the window.
* Offscreen render-to-a-texture will now be properly oriented under
DirectX (previously, it would render the texture image upside-down
and backward).
* Support for automatic keystone correction caused by an off-axis
physical projector using Lens::set_keystone().
* New framebuffer-mode prc variable allows explicit control over the
default framebuffer properties requested by Panda, including
whether software or hardware rendering is required.
* Added "multisample" transparency mode (alpha keyword "ms" in an
egg file), which allows good-quality transparency (especially for
alpha cutouts) without requiring back-to-front sorting, and
without artifacts from improper sorting. This does require
special multisample hardware capabilities, however. Presently
supported in OpenGL mode only. Automatic fallback to "binary"
transparency mode if multisample is not supported on a given
platform.
* New cursor-filename and icon-filename config variables replace the
old win32-mono-cursor and win32-window-icon variables. Also,
runtime control over these properties is now provided by the
WindowProperties class.
* Better management of potential memory leaks due to cyclic
reference counts in the RenderState and TransformState caches.
Now cycles are automatically detected and broken.
Scene graph:
* GeomNodes now have a CollideMask, just like CollisionNodes, which
deprecates the old set_collide_geom() interface to detect
collisions with visible geometry. There is a new NodePath
interface for querying and setting the collide masks for single
nodes or for entire subgraphs.
* New NodePath interfaces to control lighting eliminate the need to
create an explicit LightAttrib. The new lighting interfaces are
designed to be similar to the new multitexture interfaces.
* New NodePath interfaces to control the texture matrix, including a
new project_texture() method to enable hardware-assisted
projective texturing.
* New NodePath::flatten_multitex() interface to bake in certain
kinds of multitexture effects into a single texture, generated
on-the-fly.
* New options for ColorBlendAttrib and RenderModeAttrib.
* NodePath::set_transparancy() now accepts a
TransparencyAttrib::Mode parameter to specify exactly what kind of
transparency you'd like.
* New NodePath::set_render_mode() interface accepts a
RenderModeAttrib::Mode parameter, deprecating
set_render_mode_filled() and set_render_mode_wireframe().
* LerpQuatInterval can be used as a drop-in replacement for
LerpHprInterval; it performs spherical lerps in quaternion space,
rather than lerping each component of a HPR individually.
LerpHprInterval is not deprecated; it remains useful within its
limitations.
* New DirectSliderBar gui object implements a standard slider bar
with a thumb (like a window scroll bar).
* Lighting normals are now automatically counterscaled properly when
lighting is enabled in the presence of a scale, uniform or
nonuniform, in the scene graph. You can also use
RescaleNormalAttrib for explicit control over this behavior.
* Improvements to RopeNode for rendering splines in various
representations.
Collisions and physics systems:
* New CollisionSegment and CollisionInvSphere collision solids.
* The collision system now reports normals for intersections
detected from collision rays, segments, and lines.
* Several improvements to the physics system.
Model converters:
* x2egg and egg2x added to converters, as well as to inline
conversion supported via ptloader. This adds support for
DirectX's native so-called "retained-mode" file format. This file
format supports animation and joint hierarchies as well as basic
polygonal models.
* vrml2egg added to converters, as well as to inline conversion
supported via ptloader. This adds support for VRML 2.0 model
files only.
* Added -noabs option to many model converters, to help detect
problems with unintended absolute path references.
* Added egg2bam -flatten and -combine-geoms.
* We now have working exporters for Max5, Max6, Max7, Maya5, Maya6.
(Update: these were accidentally omitted from the binary release)
* The Max exporter is dramatically improved: it now includes support
for character studio, and the polygon winding bug has been fixed.
------------------------ RELEASE 2004-07-27 ------------------------
Configuration, installation, and execution environments:
* We have moved to a new, more explicit naming convention for our
import statements. Rather than installing all Python files into
one big flat namespace, we now import them from their appropriate
directories, e.g. "from direct.actor import Actor".
* "from ShowBaseGlobal import *" is replaced with "import
direct.directbase.DirectStart" and/or "from pandac.PandaModules
import *".
* The old "generatePythonCode" script has been replaced with a new
"genPyCode" script that automates the Python wrapper generation
process without requiring any special parameters.
* The old dependencies on environment variables have been removed.
There are no longer requirements for any environment variables to
be set in either the build process or the runtime environment
(although a few optional environment variables remain to allow
custom configuration).
* INSTALL document greatly enhanced for clarity.
* An automatic build script is now provided to further simplify
building Panda3D for Unix and Cygwin users.
* The old "Configrc" filename to identify runtime configuration
files is deprecated; configuration files should now be named
Config.prc, or in general, *.prc. The system-default
configuration files are auto-generated as 20_panda.prc,
30_pandatool.prc, and 40_direct.prc (the numeric prefixes control
the order in which these are loaded at runtime).
Rendering system:
* Some deprecated methods of CollisionEntry have been flagged to
raise an exception now; these are replaced with the newer
interfaces that can return a collision point in an arbitrary
coordinate system.
* Camera::set_cull_center() can be used for debugging culling by
setting the effective point of visibility culling different from
the actual point. From Python, use base.oobeCull() to examine
this effect.
* Alt-Enter in pview toggles between fullscreen and windowed modes.
* Added experimental support for GL display lists.
Scene graph:
* Exposed methods to directly retrieve and set the individual
vertices of a GeomNode from Python code.
* The new PortalNode defines the interface for Panda's new
cell-portal visibility system; each PortalNode is a window into
another zone, or a separate subgraph; the PortalNode can hide or
show the subset of its zone's geometry visible through its
"portal".
* The new PolylightNode applies a simple lighting-like effect
without actually using lighting; objects will brighten or darken
as a whole according to their proximity to the light. Use
PolylightEffect to enable this effect.
* The new FadeLODNode works like ordinary LODNode, but the switches
are alpha-blended in over a short period of time rather than
popping immediately.
Text display:
* Text now supports embedded mode changes--special characters to
switch fonts, colors, scale, etc. within a line or within a
paragraph.
* Windows IME is better supported by Panda/Direct widgets
(e.g. PGEntry and/or DirectEntry) in fullscreen mode as well as in
windowed mode.
Model converters:
* dxf2egg and egg2dxf added to converters, as well as to inline
conversion supported via ptloader.
------------------------ RELEASE 2004-03-29 ------------------------
Miscellaneous:
* We once again support the Microsoft VC6 compiler.
* The "pstats" program is now provided in the Windows environment as
part of pandatool. It is similar to "gtk-stats" on a Unix
environment, and can be used to view a real-time graph of
performance timing in a running Panda process. See
panda/src/doc/howto.use_pstats.
* New session recording and playback support allows capturing user
and network input to a disk file, for replaying later, offline.
Use "record-session filename.boo" and "playback-session
filename.boo" in your Configrc file.
* The genPyCode script now uses PythonWare's SqueezeTool to
"squeeze" the large number of generated .py files into a single
shared library, for substantially improved startup times on
Windows.
* The Task system now has substantially reduced overhead when many
doLater's are waiting in the system.
* The png image file type is now supported.
Rendering system:
* Introducing native DirectX9 graphics support, although we do not
yet support any features specific to DirectX9, such as
programmable shaders.
* DirectX7 and DirectX8 modules are now somewhat more robust.
* New support for offscreen rendering and render-to-a-texture, which
will become part of a general multipass-rendering interface.
Presently supported in OpenGL, with limited DirectX support. Use
GraphicsWindow::make_texture_buffer() to make a buffer you can
render into and apply the result as a texture map to objects in
your scene. The NonlinearImager in the distort directory is a
complex example of using this interface.
* Explicit support for the Mesa 3D library's software-based
offscreen rendering, allowing a Panda program to generate
offscreen images as a background process, independently of any
graphics card or desktop environment.
* GraphicsLayer and GraphicsWindow render order can now be easily
adjusted dynamically with set_sort() methods.
* Built-in frame rate meter can be activated by setting
"show-frame-rate-meter 1" in your Configrc file.
Scene graph:
* New tag system on PandaNodes allows storing of arbitrary string
data on nodes, keyed by a string dictionary. The
NodePath::get_net_tag() interface retrieves the data value for a
particular tag on a node or the nearest ancestor of the node.
NodePath::find() can search for a node in the scene graph with a
given tag or tag/value pair.
* Explicit shear transforms are now supported on nodes, as well as
in character animation tables.
* Characters now have an interface to control joint and slider
values dynamically, instead of strictly from an animation file.
Use Actor.exposeJoint() and/or Actor.controlJoint().
* Nurbs surfaces and curves can now be rendered directly by Panda,
which will tesselate them on the fly at some CPU cost. This is a
modeling convenience only; it is not intended to be used for
production code. Triangle strips are still the fastest way to
render complex surfaces.
* However, Rope.py is now provided as a high-level wrapper around
Panda's runtime NURBS curve evaluator; it can render dynamic
curves in a variety of ways.
* The egg library is now published to Python, allowing construction
of geometry on-the-fly by show code for convenience. This is also
intended as a developer's convenience more than a production
feature.
Text display:
* The special character \3 (ASCII 0x03) embedded in a text string
indicates the position of a soft hyphen when wordwrap mode is in
effect. The character \4 (ASCII 0x04) serves as a hyphenless
invisible break point.
* A default font is compiled in even if the FreeType library is not
available.
* pnmtext library added for rendering text directly into an image.
* New egg-mkfont utility uses FreeType to generate static font
models that Panda clients without FreeType can use to render text.
Collision and physics system:
* More robust collision interface, supporting NodePaths properly so
that collisions detected into (and from) particular instances of
nodes can be differentiated. CollisionEntry has a much simpler
mechanism for getting the intersection point and normal in an
arbitrary coordinate space defined by a NodePath, instead of the
user having to convert the coordinate space by hand.
* New CollisionVisualizer object to visually show collisions as they
are tested and detected, useful for optimizing collision
performance. Activate this with
base.cTrav.showCollisions(render).
* Implicit velocity system is now integrated with scene graph; the
relative velocity of moving nodes is automatically considered when
testing for most kinds of collisions. Use
NodePath::set_fluid_pos() to indicate that a node is moving
fluidly to its new position and should test for collisions along
the way (as opposed to the more traditional NodePath::set_pos(),
which unconditionally sets the node to its new position).
* Introduction of "tube" collision shapes, sometimes called
"capsules" in other libraries. It is a cylinder capped with
hemispheres.
* CollisionSolid::set_effective_normal() provides a way to define a
sloping surface with an apparently vertical normal, to prevent
characters standing on the surface from sliding down.
* Collision polygons now respect clipping planes.
* Many changes to physics system.
HTTPClient and net systems:
* More verbose error reporting.
* Better support for proxy servers, including SOCKS5 proxies.
Model converters:
* maya2egg converter now supports skeleton/morph animation files
fully, including soft-skinning, hard-skinning, and morphs (blend
shapes). NURBS and polygon meshes are both supported.
* A new Maya plugin called libmayapview allows opening a Panda
window from within Maya to view how the scene will look once it
has been converted to Panda.
* New soft2egg converter supports models and animation stored in
SoftImage 4.3 files. (Newer versions of SoftImage are not
supported.)
* New egg2flt program more or less reverses flt2egg.
* The ptloader Panda loader allows direct loading into Panda of most
model file types defined within pandatool: Maya, flt, and lwo.
Specify load-file-type ptloader in your Configrc file.
* New egg-optchar preprocessor improves character animation runtime
performance by eliminating unneeded joints. It can also
reorganize a skeleton and/or expose joints for the show code's
convenience.
* New egg-qtess utility converts NURBS egg files to polygon egg
files with either a trivial interface for quick conversions or a
sophisticated parameter file for more precise control. It
preserves soft-skinning and animation information.
* New visibility flag in egg format allows model files to define
invisible subtrees which will be initially stashed when loaded.
* The egg library now allows implicit forward references to vertex
pools, making it much easier to generate a valid egg file from a
third-party model format.
