[jitter] Re: Re: Re: Re: [sharing is fun] projective texture isosurfer

Well, if it's coming out black then there is something to do with Cg
and the shader that's not working on your machine.  Can you verify if
the mat.phong.cg.jxs shader works for you?  If so, go into the
projective texture shader and comment out the entire fragment shader
and add a line that just assigns a color like red to every pixel.  If
this works, keep uncommenting more code until it fails.  This will
tell myou what is going on.

I wanted to make a screenshot of this but osx can't seem to make a screenshot of the entire screen (without the necessity of using the mouse).
