Detailed Description

The TransformInfo node provides information about the coordinate space it resides in in the scene graph.

The accForwardMatrix field is the matrix that transforms from the local coordinate space where this Node resides in the scenegraph to global space.

The accInverseMatrix field is the matrix that transforms from the global coordinate space to the coordinate space this Node resides in in the scenegraph.

The outputGLMatrices field determines if the OpenGL matrix fields should be updated or not(the fields starting with gl). Note that when this is true graphics caching will disabled for this node making all parent nodes not being cached. This is most of the time a non-issue though.

The glModelViewMatrix is The OpenGL GL_MODELVIEW_MATRIX at the current point of the transform hierarchy.

The glModelViewMatrixInverse field is the inverse matrix of glModelViewMatrix.

The glProjectionMatrix is The OpenGL GL_PROJECTION_MATRIX at the current point of the transform hierarchy.

The glProjectionMatrixInverse field is the inverse matrix of glProjectionMatrix.
