Callbacks are registered with this class using helper functions. Those callbacks are invoked indirectly by the VR Juggler kernel through the vrj::App and vrj::GlApp interface methods implemented in this class.

Function that is called immediately after a new context is created.
Use this function to create context-specific data structures such as display lists and texture objects that are known to be required when the context is created.
Reimplemented from vrj::GlApp.
Definition at line 55 of file GlProcApp.cpp.
References mContextInit.

| void vrj::GlProcAppWrapper::preFrame | ( | ) | [virtual] |
Executes any code needed to set up the application object state prior to rendering the scene.
This is invoked by the kernel once per pass through the Juggler frame loop. This is called after input device updates but before the start of rendering a new frame of the scene.

| void vrj::GlProcAppWrapper::intraFrame | ( | ) | [virtual] |
Function called during this application's drawing time.
This can be used for "free" parallel processing, but it introduces a critical section to the code. If the rendering process is reading state data, this method should not be modifying any of that data. Instead, a double- or triple-buffering scheme must be used to allow parallel reading and writing of all application state used for rendering.

| void vrj::GlProcAppWrapper::postFrame | ( | ) | [virtual] |
Function called before updating input devices but after the frame rendering is complete.
Reimplemented from vrj::App.

References mPostframeMethod.

| void vrj::GlProcAppWrapper::bufferPreDraw | ( | ) | [virtual] |
Function that is called once for each frame buffer of an OpenGL context.
This function is executed after contextInit() (if needed) but before contextPreDraw(). It is called once per frame buffer (see note).
Reimplemented from vrj::GlApp.
Definition at line 87 of file GlProcApp.cpp.

| void vrj::GlProcAppWrapper::draw | ( | ) | [virtual] |
Function that renders the scene.
Override this function with the user rendering routine.
