Re: Cihan Ula
If you are using 64 bit version of matlab, you will need 64 bit version of glut and glew, glut32 and GLEW32 won't work in this case.

I cannot reproduce the crash on leopard, and I don't have a snow leopard to test with. Judging from the error message, you could try add a dummy display callback, by calling

void glutDisplayFunc(void (*func)(void));

after glutCreateWindow in OffscreenGL's constructor.

see glut's spec for more details

The spaces in your GlewPath & GlutPath are causing the issue. Try to use "C:\DOCUME~1" in the path.

The package are tested in mac, but it should also work in windows once you set the correct include and lib path. Unfortunately I don't have Windows version of matlab at hand to test it out.

For windows, you will need to download the GLUT and GLEW binaries:
GLUT: http://www.xmission.com/~nate/glut.html
GLEW: http://glew.sourceforge.net/

Extract both zip files, GLEW will extract to a set of bin/, include/, doc/, lib/ folders. You could copy glut.h into glew/include/GL, glut32.lib into glew/lib/, so that they share the same path. And copy glew32.dll and glut32.dll into the offscreen root folder.

Then you could use modify the path in CompileOffscreen.m to something like this:

GlewPath = '-I./glew/include -L./glew/lib -lGLEW';
GlutPath = '-lglut';

You should be able to compile it now. Let me know if you have further problems.

I can compile and run the MEX functions. However, the offscreen window is not dismissed. When I click to close the window, Matlab crashes hard.

My setup:

Windows 7 x64
ATI FirePro V8800
Matlab R2011b (x64)
Visual Studio 2010 express
Microsoft Windows SDK 7.1
Freeglut 2.6.0 (compiled to x64 library)
GLEW 1.7.0 (static / -DGLEW_STATIC)

Anyone with a similar configuration?

I used Freeglut because it seemed more recent and had a visual C project file compatible with VC Express 2010.

It seems it does not work in x64 Win7.
For x86, I used the following conf. and it worked propoerly.
1. Download glut and glew and extract them under C:\ path. They should be located as C:\glew and C:\glut.
2.Use the following paths which are found in CompileOffscreen file, which is located in offscreen folder.

GlewPath = '-IC:/glew/include -LC:/glew/lib -lGLEW32';
-LC:/glew/lib -lglut32';
GlutPath = '-IC:/glut -LC:/glut -lglut32';

People interested in Using OpenGL from MATLAB should have a look at the PsychToolBox (PTB), a library with extensive abilities that is used predominantly by vision researchers to program up their stimuli in MATLAB and display them through OpenGL. It includes MoGL, a Matlab wrapper around just about all OpenGL functionality, although PTB it also contains higher level functions, e.g. for easy drawing of dots, or procedural creation of Gabor patches.
