Detailed Description

The SbSpherePlaneProjector class projects 2D points to a half-sphere and a plane.

This projector uses a plane along with the half-sphere of SbSphereSectionProjector for projections. If the 2D point mapping "misses" the sphere section, the 3D point will be projected onto the plane.

SbSpherePlaneProjector::SbSpherePlaneProjector (  const float edgetol = 0.9f, const SbBool orienttoeye = TRUE )

Default constructor. See SbSphereSectionProjector::SbSphereSectionProjector().

SbSpherePlaneProjector::SbSpherePlaneProjector (  const SbSphere & sph, const float edgetol = 0.9f, const SbBool orienttoeye = TRUE )

Constructor with explicit specification of projection sphere.

Member Function Documentation

SbProjector * SbSpherePlaneProjector::copy (  void )  const [virtual]

Construct and return a copy of this projector. The caller is responsible for destructing the new instance. Reimplemented from SbSphereSectionProjector.

SbVec3f SbSpherePlaneProjector::project (  const SbVec2f & point )  [virtual]

Project the 2D point from normalized viewport coordinates to a 3D point. The mapping will be done in accordance with the type of the projector. Reimplemented from SbSphereSectionProjector.

SbRotation SbSpherePlaneProjector::getRotation (  const SbVec3f & point1, const SbVec3f & point2 )  [virtual]

Returns rotation on the projection surface which re-orients point1 to point2. Reimplemented from SbSphereSectionProjector.

SbRotation SbSpherePlaneProjector::getRotation (  const SbVec3f & point1, const SbBool tol1, const SbVec3f & point2, const SbBool tol2 )  [protected]

Calculates rotation from point1 to point2, with tol1 and tol2 deciding whether or not to use the tolerance setting.
