public class SbSphereProjector
extends SbProjector

Sphere projector. SbSphereProjector is an abstract base class for projectors that use a sphere in their projection. Sphere projectors are typically used to write interactive 3D manipulators and viewers.

Method Detail

getRotation

public SbRotation getRotation(SbVec3f point1,
                              SbVec3f point2)

Gets a rotation given two points on this sphere projector. The rotation will be on the surface of the sphere.

isOrientToEye

public boolean isOrientToEye()

Gets whether the projector should always be oriented towards the eye.

projectAndGetRotation

public SbRotation projectAndGetRotation(SbVec2f point)

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.

getSphere

public SbSphere getSphere()

Gets the sphere on which to project points.

setFront

public void setFront(boolean 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.

setOrientToEye

public void setOrientToEye(boolean orientToEye)

Sets whether the projector should always be oriented towards the eye. Set to false if the tolerance should be evaluated in working space.

isPointInFront

public boolean isPointInFront(SbVec3f point)

Gets whether the projector should intersect the half of the sphere that faces the eye.

setSphere

public void setSphere(SbSphere sph)

Sets the sphere on which to project points. The default sphere has radius 1.0.

isFront

public boolean isFront()

Gets whether the projector should intersect the half of the sphere that faces the eye.
