[GEM-dev] [Fwd: Re: [PD] gem, shader and framebuffer]

[Hans-Christoph Steiner]

I couldnt' get the previous example to work beyond drawing a slowing  
moving square on my screen (i.e. no sphere).  This one seems to work,  
I get some crazy multi-color strobing in a kind of box like shape.   
I'm glad that you guys are working this stuff.  If anyone wants to  
make some examples and/or a help patch for gemframebuffer, I'll  
happily check them into CVS.
