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 glDraw(), etc.

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.
