Gets a rotation given two points on this sphere projector.
The rotation will be on the surface of the sphere.
Implemented in SbSpherePlaneProjector, SbSphereSectionProjector, and SbSphereSheetProjector.

Gets the sphere on which to project points.
Definition at line 122 of file SbSphereProjector.h.
Applies the projector using the given line in world coordinates, returning the point in three dimensions that it projects to.
New for v3.0.
Implements SbProjector.
Implemented in SbSpherePlaneProjector, SbSphereSectionProjector, and SbSphereSheetProjector.

Gets whether the projector should always be oriented towards the eye.
Definition at line 132 of file SbSphereProjector.h.
Gets whether the projector should intersect the half of the sphere that faces the eye.
Applies the projector using the given point, returning the point in three dimensions that it projects to.
The point should be normalized from 0-1, with (0,0) at the lower-left.
Implements SbProjector.
Implemented in SbSpherePlaneProjector, SbSphereSectionProjector, and SbSphereSheetProjector.
SbVec3f SbSphereProjector::projectAndGetRotation | ( | const SbVec2f & | point, |
SbRotation & | rot | ||
) |
Applies the projector using the given point, returning the point in three dimensions that it projects to.
This also returns in rot a rotation on the surface of the sphere from the last projected point to this one. The passed point should be normalized (i.e. lie in the range [0.0,1.0]), with (0,0) at the lower-left.
void SbSphereProjector::setFront | ( | SbBool | inFront | ) |
Sets whether the projector should intersect the half of the sphere that faces the eye.
Set to FALSE if the projector should intersect with the rear half.
void SbSphereProjector::setOrientToEye | ( | SbBool | orientToEye | ) |
Sets whether the projector should always be oriented towards the eye.
Set to FALSE if the tolerance should be evaluated in working space.
void SbSphereProjector::setSphere | ( | const SbSphere & | sph | ) |
Sets the sphere on which to project points.
The default sphere has radius 1.0.
|
virtual |
Sets the transform space to work in.
