Default constructor sets up a sphere at the origin with radius 1.

Constructor taking an explicit sphere projection definition.

Project the 2D point to a 3D coordinate on the spherical surface, and find the rotation from the last projection to this one.

project(), getRotation()

Returns rotation on the projection surface which reorients point1 to point2.

Implemented in SbSpherePlaneProjector, SbSphereSectionProjector, and SbSphereSheetProjector.

Set sphere to project onto.

Returns projection sphere.

Sets whether or not the projection surface should be oriented towards the eye of the viewer. Default is TRUE.

Returns the state of the sphere orientation flag.

Set whether to intersect with the outside of the sphere (infront equal to TRUE), or the inside.

Returns value of the flag which decides whether to intersect with the outside or inside of the sphere.

Check if point is on the front side or the back side of the cylinder.

Sets the matrix used for converting from the projector's coordinate system to the world coordinate system.

Reimplemented from SbProjector.

Intersect line with the SbSphereProjector::sphere and place the intersection point (if any) in result. Considers setFront() settings.

Returns TRUE if line actually hits the sphere, FALSE if it doesn't intersect with it.

Flag which says whether or not we should map to the outside or inside of the sphere surface.

Projection sphere.

Which direction the spherical surface is oriented.

Set to TRUE whenever the projection surface needs to be recalculated according to the setting of the SbSphereProjector::orientToEye flag.

Stores the previously projected 3D point.
