[Vis5d-users] Re: PC X-Server Emulation

Dear Michael,

I have followed your suggestions and I can now display Vis5D on my PC
X-server.  As you suggested, I have tried the Hummingbird Exceed 3D product
which has the OpenGL library.  That software installation got rid of the
software error message

Xlib:  extension "GLX" missing on display "my sgi:0.0".

I still received the hardware error message

Error: couldn't get RGB, Double-Buffered, Depth-Buffered GLX visual!

So I switched to a video card with hardware OpenGL as you suggested and now
all works fine.  The card I am using is a "64MB DDR NVIDIA GeForce2 GTS
(Dell)" product.  Thanks for your help.

Cheers, David
