In the cube VA example change GLubyte to GLuint and GL_UNSIGNED_BYTE to
GL_UNSIGNED_INT, no more crashes (don’t ask me why)
VBOs and vertexarrays are working, tested on stanford models within custom
tool...

Subject: SDK : using vertex arrays in a custom tool?
hey brent!
i was reading about vertex arrays...
http://www.songho.ca/opengl/gl_vertexarray.html
i tried to implement this and got crashes, before i investigate further are
these even usable? or is custom tools restricted to immediate mode?
how about VBOs and display lists? any restrictions with these open gl features?
thanks!
