Constructor & Destructor Documentation
◆ SbPlaneProjector() [1/2]
| SbPlaneProjector::SbPlaneProjector | ( | bool | orient = FALSE | ) |
The default plane passes through the origin and is oriented perpendicular to the Z axis.

Member Function Documentation
◆ copy()
|
virtual |
The caller is responsible for deleting the copy when done.
Implements SbProjector.
◆ getPlane()
|
inline |
Definition at line 107 of file SbPlaneProjector.h.
◆ getVector() [1/2]
Uses the last point on this projector from the previous call to getVector() or setStartPostion(). Do not use this if the working space transform is changing since the new point will be in a different space than the old one.
◆ getVector() [2/2]

◆ isOrientToEye()
|
inline |
Definition at line 117 of file SbPlaneProjector.h.
◆ project()
The point should be normalized from 0-1, with (0,0) at the lower-left.
Implements SbProjector.
◆ setOrientToEye()
| void SbPlaneProjector::setOrientToEye | ( | bool | orientToEye | ) |
If orientToEye is set to TRUE, the given plane's direction is ignored, and the plane will be oriented to the eye. It will pass through the same point from the origin defined by the original dir * dist. Set to FALSE if the plane's direction should remain in working space.
◆ setPlane()
| void SbPlaneProjector::setPlane | ( | const SbPlane & | plane | ) |
◆ setStartPosition() [1/2]
