/**
|
||
|
|
* The method used in creating the motion trail is based on taking samples of
|
||
|
|
* time and transformations (the position and orientation matrix) in real-
|
||
|
|
* time. The method also requires a number of vertices (positions) that
|
||
|
|
* determines "shape" of the motion trail (i.e. the edge of a blade). A
|
||
|
|
* start color and end color is also required for each vertex. The color is
|
||
|
|
* interpolated as function of time. The colors are typically used to fade
|
||
|
|
* the motion trail so the end color is typically black.
|
||
|
|
*
|
||
|
|
* The vertices are submitted via the "add_vertex" function. For each frame,
|
||
|
|
* a sample is submited via the "update_motion_trail" function. During the
|
||
|
|
* "update_motion_trail" function, the motion trail geometry is created
|
||
|
|
* dynamically from the sample history and the vertices.
|
||
|
|
*
|
||
|
|
* The user must specifiy a GeomNode via "set_geom_node".
|
||
|
|
*
|
||
|
|
* The duration of the sample history is specified by a time window. A larger
|
||
|
|
* time window creates longer motion trails (given constant speed). Samples
|
||
|
|
* that are no longer within the time window are automatically discarded.
|
||
|
|
*
|
||
|
|
* The nurbs option can be used to create smooth interpolated curves from the
|
||
|
|
* samples. The nurbs option is useful for animations that lack sampling to
|
||
|
|
* begin with, animations that move very quickly, or low frame rates.
|
||
|
|
*
|
||
|
|
* The texture option be used to create variation to the motion trail. The u
|
||
|
|
* coordinate of the texture corresponds to time and the v coordinate
|
||
|
|
* corresponds to the "shape" of the motion trail.
