What am I doing wrong here? On paper it looks fine, however I'm not doing inverted X axis as trienco and I have all of my positions "inverted" like this:

   

	float view[16] ={     transform[0], transform[4], transform[8], 0,
						  transform[1], transform[5], transform[9], 0,
						  transform[2], transform[6], transform[10], 0,

						  -(transform[0]*transform[12] +
						  transform[1]*transform[13] +
						  transform[2]*transform[14]),

						  -(transform[4]*transform[12] +
						  transform[5]*transform[13] +
						  transform[6]*transform[14]),

						  -(transform[8]*transform[12] +
						  transform[9]*transform[13] +
						  transform[10]*transform[14]), 1};
