public class SoTransformProjection extends SoProjection
SoProjection
which applies a scale and recenter to a geometry.
The computation is done on the CPU before the transfer to OpenGL. The main purpose of this feature is to transform the vertex coordinates before sending them to OpenGL in order to avoid single precision issues, especially with the depth buffer.
Essentially this is a convenience node that automatically creates an SbTransformProjection
and calls the setProjection()
method for you.
The result of a bounding box action is the coordinates of the bounding box after the projection because we need this version of the bounding box for rendering/clipping.
See SoProjection
for important limitations of projection nodes.
