This class provides a C++ interface to a simple GL window using GLUT. By utilizing this class, it provides a common interface for other things in the CPPGPGPU library without increasing code common to all of the projects.

| ) |
Initialization function, call this before doing anything else.
This must be called AFTER you use GLUTCore's callbacks and before pretty much anything else with GLUT you can simply call this immediately after main with the parameters from your main() function as well as the initial width, height and title for the window
Definition at line 135 of file GLUTCore.cpp.
| void GLUTCore::DrawAndDoMainLoop | ( | ) |
Main GLUT Loop call.
Call this after you've done everything you want to have execute once. This is what causes the different callbacks to get called over and over.

| float GLUTCore::TackFPS | ( | ) |
FPS Tack and Get Delta Time.
This function updates the internal (GLUTCore) timers and if a second has been past, it will display FPS. It will always return the total time between last frame and this frame

| void GLUTCore::SetCamDist | ( | const float | fDist | ) | [inline] |
Set camera distance for default distance on reshape.
Whenever the viewport is resized, the default change viewport function gets called and that looks at the camera distance to generate the apropriate camera transformations
