mrpt::opengl::mrptEventGLPreRender Class Reference

Detailed Description

An event sent by an mrpt::opengl::COpenGLViewport just after clearing the viewport and setting the GL_PROJECTION matrix, and before calling the scene OpenGL drawing primitives.

While handling this event you can call OpenGL glBegin(),glEnd(),gl* functions or those in mrpt::opengl::gl_utils to draw stuff in the back of the normal objects contained in the COpenGLScene.

After processing this event, COpenGLViewport will change the OpenGL matrix mode into "GL_MODELVIEW" and load an identity matrix to continue rendering the scene objects as usual. Any change done to the GL_PROJECTION will have effects, so do a glPushMatrix()/glPopMatrix() if that is not your intention.

IMPORTANTE NOTICE: Event handlers in your observer class will most likely be invoked from an internal GUI thread of MRPT, so all your code in the handler must be thread safe.
