Cylinder projector.
SbCylinderProjector is an abstract base class for projectors that use a cylinder in their projection. The getRotation() method for an SbCylinderProjector will always return a rotation that is about the axis of the cylinder. Cylinder projectors are typically used to write interactive 3D manipulators and viewers.

Definition at line 137 of file SbCylinderProjector.h.
Gets whether the projector should intersect the half of the cylinder 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.

SbVec3f SbCylinderProjector::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 about the axis of the cylinder 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 SbCylinderProjector::setCylinder | ( | const SbCylinder & | cyl | ) |
Sets the cylinder on which to project points.
The default cylinder is aligned with the Y axis and has radius 1.0.
void SbCylinderProjector::setFront | ( | SbBool | isFront | ) |
Sets whether the projector should intersect the half of the cylinder that faces the eye.
Set to FALSE if the projector should intersect with the rear half.
void SbCylinderProjector::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.
|
virtual |
Sets the transform space to work in.
