Functions

gutz::mat3f ballPlaneRot (const gutz::vec3f &center, const float rad, const gutz::CameraSP cam, const gutz::vec3f &last, const gutz::vec3f &curr)
 current mouse point (world space)

gutz::mat4f ballPlane (const gutz::MouseMoveEvent &mme, const gutz::vec3f &center, const float rad)
 a convenience version of ballPlaneRot that takes the event and the objects center & rad, calls ballPlaneRot and builds a 4x4 matrix from the result.
