// Class : ProjectionScreen
// Description : A ProjectionScreen implements a simple system for

// particular texture stage) on its subordinate geometry

// parameters of the indicated LensNode.
//
// All this does is recompute UV's; the caller is

// to the geometry.
//
// This does not take advantage of any hardware-assisted
// projective texturing; all of the UV's are computed in
// the CPU. (Use NodePath::project_texture() to enable
// hardware-assisted projective texturing.) However,
// the ProjectionScreen interface does support any kind
// of lens, linear or nonlinear, that might be defined
// using the Lens interface, including fisheye and

// Class : NonlinearImager
// Description : This class object combines the rendered output of a
// 3-d from one or more linear (e.g. perspective)
// cameras, as seen through a single, possibly nonlinear
// camera.
//
// This can be used to generate real-time imagery of a
// 3-d scene using a nonlinear camera, for instance a
// fisheye camera, even though the underlying graphics
// engine may only support linear cameras. It can also
// pre-distort imagery to compensate for off-axis
// projectors, and/or curved screens of any complexity.
//
//
// A NonlinearImager may be visualized as a dark room
// into which a number of projection screens have been
// placed, of arbitrary size and shape and at any
// arbitrary position and orientation to each other.
// Onto each of these screens is projected the view as
// seen by a normal perspective camera that exists in
// the world (that is, under render).
//
// There also exist in the room one or more (possibly
// nonlinear) cameras, called viewers, that observe
// these screens. The image of the projection screens
// seen by each viewer is finally displayed on the
// viewer's associated DisplayRegion. By placing the
// viewer(s) appropriately relative to the screens, and
// by choosing suitable lens properties for the
// viewer(s), you can achieve a wide variety of
// distortion effects.
//
//
// There are several different LensNode (Camera) objects
// involved at each stage in the process. To help keep
// them all straight, different words are used to refer
// to each different kind of Camera used within this
// object. The camera(s) under render, that capture the
// original view of the world to be projected onto the
// screens, are called source cameras, and are set per
// screen via set_source_camera(). The LensNode that is
// associated with each screen to project the image as
// seen from the screen's source camera is called a
// projector; these are set via the
// ProjectionScreen::set_projector() interface.
// Finally, the cameras that view the whole
// configuration of screens are called viewers; each of
// these is associated with a DisplayRegion, and they
// are set via set_viewer_camera().
//
// Of all these lenses, only the source cameras must use
// linear (that is, perspective or orthographic) lenses.
// The projectors and viewers may be any arbitrary lens,
// linear or otherwise.

//
// A NodePath is the fundamental unit of high-level interaction with
// the scene graph. It encapsulates the complete path down to a node
// from some other node, usually the root of the scene graph. This is
// used to resolve ambiguities associated with instancing.
//
// NodePath also contains a number of handy high-level methods for
// common scene-graph manipulations, such as reparenting, and common
// state changes, such as repositioning.
//
// There are also a number of NodePath methods for finding nodes deep
// within the tree by name or by type. These take a path string,
// which at its simplest consists of a series of node names separated
// by slashes, like a directory pathname.
//
// Each component of the path string may optionally consist of one of
// the following special names, instead of a node name:
//
// * -- matches exactly one node, with any name.
// ** -- matches any sequence of zero or more nodes.
// +typename -- matches any node that is or derives from the given type.
// -typename -- matches any node that is the given type exactly.
// =tag -- matches any node that has the indicated tag.
// =tag=value -- matches any node whose tag matches the indicated value.
//
// Furthermore, a node name may itself contain standard filename
// globbing characters, like *, ?, and [a-z], that will be accepted as
// a partial match. (In fact, the '*' special name may be seen as
// just a special case of this.) The globbing characters may not be
// used with the typename matches or with tag matches, but they may
// be used to match a tag's value in the =tag=value syntax.
//
// The special characters "@@", appearing at the beginning of a node
// name, indicate a stashed node. Normally, stashed nodes are not
// returned by a find (but see the special flags, below), but a
// stashed node may be found if it is explicitly named with its
// leading @@ characters. By extension, "@@*" may be used to identify
// any stashed node.
//
// Examples:
//
// "room//graph" will look for a node named "graph", which is a child
// of an unnamed node, which is a child of a node named "room", which
// is a child of the starting path.
//
// "**/red*" will look for any node anywhere in the tree (below the
// starting path) with a name that begins with "red".
//
// "**/+PartBundleNode/**/head" will look for a node named "head",
// somewhere below a PartBundleNode anywhere in the tree.
//
//
// The search is always potentially ambiguous, even if the special
// wildcard operators are not used, because there may be multiple
// nodes in the tree with the same name. In general, in the case of
// an ambiguity, the shortest path is preferred; when a method (such
// as extend_by) must choose only only one of several possible paths,
// it will choose the shortest available; on the other hand, when a
// method (such as find_all_matches) is to return all of the matching
// paths, it will sort them so that the shortest paths appear first in
// the output.

// Class : NodePath
// Description : NodePath is the fundamental system for disambiguating
// instances, and also provides a higher-level interface
// for manipulating the scene graph.
//
// A NodePath is a list of connected nodes from the root
// of the graph to any sub-node. Each NodePath
// therefore uniquely describes one instance of a node.
//
// NodePaths themselves are lightweight objects that may
// easily be copied and passed by value. Their data is
// stored as a series of NodePathComponents that are
// stored on the nodes. Holding a NodePath will keep a
// reference count to all the nodes in the path.
// However, if any node in the path is removed or
// reparented (perhaps through a different NodePath),
// the NodePath will automatically be updated to reflect
// the changes.

// Description : This is a sequence number that increments

//
// A special class is used instead of simply an int, so
// we can elegantly handle such things as wraparound and
// special cases. There are two special cases.
// Firstly, a sequence number is 'initial' when it is
// first created. This sequence is older than any other
// sequence number. Secondly, a sequence number may be
// explicitly set to 'old'. This is older than any
// other sequence number except 'initial'. Finally, we
// have the explicit number 'fresh', which is newer
// than any other sequence number. All other sequences
// are numeric and are monotonically increasing.

// Class : GraphicsOutput
// Description : This is a base class for the various different
// classes that represent the result of a frame of
// rendering. The most common kind of GraphicsOutput is
// a GraphicsWindow, which is a real-time window on the
// desktop, but another example is GraphicsBuffer, which
// is an offscreen buffer.
//
// The actual rendering, and anything associated with
// the graphics context itself, is managed by the
// associated GraphicsStateGuardian (which might output
// to multiple GraphicsOutput objects).
//
// GraphicsOutputs are not actually writable to bam
// files, of course, but they may be passed as event
// parameters, so they inherit from
// TypedWritableReferenceCount instead of
// TypedReferenceCount for that convenience.

// Class : DisplayRegion
// Description : A rectangular subregion within a window for rendering
// into. Typically, there is one DisplayRegion that
// covers the whole window, but you may also create
// smaller DisplayRegions for having different regions
// within the window that represent different scenes.
// You may also stack up DisplayRegions like panes of
// glass, usually for layering 2-d interfaces on top of
// a 3-d scene.

// Class : GraphicsEngine
// Description : This class is the main interface to controlling the

// GraphicsEngine in an application, and it synchronizes
// rendering to all all of the active windows; although
// it is possible to have multiple GraphicsEngine
// objects if multiple synchronicity groups are
// required.
//
// The GraphicsEngine is responsible for managing the
// various cull and draw threads. The application
// simply calls engine->render_frame() and considers it
// done.
