Activate/Deactivate the ground plane.
Returns true if the ground plane is activated.
Initializes FieldRendering for video output. This function is called once before the rendering starts. If FieldRendering is on, the rendering Module will render twice as many frames as it will output, then it will mix the even and odd lines from two frames to build one frame.
You should use I3DRenderHelper::RenderArea() instead.
use DirectionFilter2 instead. Calculates the effect of the atmosphere on an infinite ray.
use SegmentFilter2 instead. Calculates the effect of the atmosphere on a finite line segment on a ray.
Do not implement at this point.
