Member Function Documentation

Matrix4D StaticRayGroup::getInverseMatrix (  void   )  [virtual]

This method returns the inverse of the transformation associated with the group. Implements RayGroup.

Matrix4D StaticRayGroup::getMatrix (  void   )  [virtual]

This method returns the transformation associated with the group. Implements RayGroup.

Matrix4D StaticRayGroup::getNormalMatrix (  void   )  [virtual]

This method returns the transformation that acts on the surface normals. Implements RayGroup.

int StaticRayGroup::isStatic (  void   )  [virtual]

This method returns a value of 1 if the RayShape's geometry doesn't change. Reimplemented from RayShape.

int StaticRayGroup::read (  FILE *  fp  )

This method reads in the transformation matrix from a .ray file.

int StaticRayGroup::set (  Matrix4D  xForm  )

This method sets the the transformation matrix of the node.

void StaticRayGroup::writeBegin (  int  indent, FILE *  fp = stdout )  [virtual]

This virtual method specifies how the header of the node should be written out to a .ray file. Implements RayGroup.

void StaticRayGroup::writeEnd (  int  indent, FILE *  fp = stdout )  [virtual]

This virtual method specifies how the footer of the node should be written out to a .ray file. Implements RayGroup.
