I don't think cause the opengl state is common between both threads so
each opengl function call will act on the machine state shared in the
driver  and on the graphic card.

Hi All,

I am relatively new to the list and I am still learning.  I am working on a
3D game (personal learning project at the moment) and I am trying to spawn a
new thread at a certain point in my code.  The purpose of this thread is to
pull objects, models and textures from files into memory (for OpenGL) while
I am continuing to render in the primary thread.

So far I have created a thread and the thread spawns OK.  It starts running
but during the loading process I am getting access violation errors when
trying to access arrays of GLuint variables (for the textures).  At this
point the arrays are not in use by the primary thread so I thought I would
be able to avoid using any sort of mutex.  I am still new to multi-threading
and I am using the standard WINAPI CreateThread() function.

Can anyone offer any advice on how to do this or point me to any good
tutorials online.

Thanks

Richard
