||||
* texture coordinate across two vertices, something simple like
|
||||
* u = (u0*w0 + u1*w1)/(w0+w1)
|
||||
* will not work. However, the attribute value divided by the
|
||||
* clipspace w-coordinate (u/w) and and the inverse w-coordinate (1/w) are linear
|
||||
* in screenspace. Hence, we can linearly interpolate these two independently and
|
||||
* calculate the interpolated attribute by dividing the results.
|
||||
* I.e.
|
||||
* u_over_w = ((u0/v0.pos.w)*w0 + (u1/v1.pos.w)*w1)/(w0+w1)
|
||||
* one_over_w = (( 1/v0.pos.w)*w0 + ( 1/v1.pos.w)*w1)/(w0+w1)
|
||||
* u = u_over_w / one_over_w
|
||||
*
|
||||
* The generalization to three vertices is straightforward in baricentric coordinates.
