- CaptureWorld 'captures' the properties (position, rotation, scale, alpha etc) of each entity in the 3D world.
<br />
-
<br />
- This is then used in conjunction with the <a class=small href=../3d_commands/RenderWorld.htm>RenderWorld</a> tween parameter in order to render an interpolated frame between the captured state of each entity and the current state of each entity. See the <a class=small href=../3d_commands/RenderWorld.htm>RenderWorld</a> docs for a full explanation of render tweening.
