Detailed Description

Scale/recenter projection class

This class implements a projection that applies a scale and recenter to geometry.

This class can be used with an SoProjection node, but mainly exists to be used internally by the SoTransformProjection node.

Member Function Documentation

◆ getProjectedBoundingBox()

bool SbTransformProjection::getProjectedBoundingBox ( SbBox3f & bbox )

inlinevirtual

Compute projected bounding box.

As this projection is linear, projecting a bounding box is equivalent to the bbox of the projected points. Defining this method speeds up some rendering nodes.

Reimplemented from SbProjection.
