public class SoTransformProjection extends SoProjection
Scale/recenter projection node. This property node is a specificSoProjection
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 thesetProjection()
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.
