Opengl programming for mac os x

The tutorial page has an Xcode project which builds and runs properly , but it uses Objective-C which I do not know , and has a lot of code which is foreign to me the. You aren't issuing a buffer swap which is a requirement for double buffered OpenGL contexts like the one you are attempting to setup here.

This can be corrected by adding the following statement after the final glEnd call contained within your DrawGLScene method How did you read my code so quickly?

OpenGL Programming on Mac OS X: Architecture, Performance, and Integration

How did you know the answer immediately that one function did the trick? Why wasn't this glutSwapBuffers included in the sample code? What part of the code indicates that I am attempting to use a double-buffered OpenGL context? The documentation says that the function basically pushes the contents of the back buffer to the front buffer. That makes enough sense to me, but I'm still wondering why or where my code implies a double-buffered OpenGL context or is this due to OS X double buffering all windows?

Apologies for the inane questions, but anything visual or display-oriented goes way over my head. Thanks for explaining "my own" code to me yes, I realize how amateurish this is.

However, if I remove that bit from the flag, I still need glutSwapBuffers before anything is drawn to the screen. You need a call to glutSwapBuffers in order to swap between the front and back buffer s during rendering as you are using a double buffered OpenGL context. View larger cover.

The Mac has fully embraced OpenGL throughout its visual systems. They illuminate crucial OpenGL setup, configuration, and performance issues that are unique to the Mac platform. Next, they offer practical, start-to-finish guidance for integrating key Mac-native APIs with OpenGL, and leveraging the full power of the Mac platform in your graphics applications. Robert P.
