/** Callback class to update the state of the \p projection, \p view, \p transform and \p normal matrices of a GLSLProgram or fixed function pipeline.
|
|
* By default it updates the GL_PROJECTION and GL_MODELVIEW matrices. If GLSL is used and any of \p vl_ModelViewMatrix, \p vl_ProjectionMatrix,
|
|
* \p vl_ModelViewProjectionMatrix or \p vl_NormalMatrix is used, then no legacy uniform matrix is updated (GL_MODELVIEW, gl_ModelViewMatrix etc.)
|
|
* but only the vl_* ones.
|
|
* Reimplement the updateMatrices() method to update any other camera/transform matrix you might need such as the ones defined in
|
|
* http://www.opengl.org/registry/doc/GLSLangSpec.Full.1.10.59.pdf pag 45.
