You mean instead of clipping something step by step, you want to 
calculate the intersectionpoint of 3 planes analytically?

I went there and its a horror. I doubt that you would gain any precision 
since the calculation is dominated by a huge division AND/OR inverse of 
a 3x3 matrix (depends on your approach).
