|
|
* dst.z = pow(max(0.0, src.y) * step(0.0, src.x), power);

*
|
|
* step(0.0, x) will return 1 if src.x > 0.0, and 0 otherwise. So if y is 0 we get pow(0.0 * 1.0, power),
|
|
* which sets dst.z to 0. If y > 0, but x = 0.0, we get pow(y * 0.0, power), which results in 0 too.
|
|
* if both x and y are > 0, we get pow(y * 1.0, power), as it is supposed to.
|
|
*
|
|
* Unfortunately pow(0.0 ^ 0.0) returns NaN on most GPUs, but lit with src.y = 0 and src.w = 0 returns
|
|
* a non-NaN value in dst.z. What we return doesn't matter, as long as it is not NaN. Return 0, which is
|
|
* what all Windows HW drivers and GL_ARB_vertex_program's LIT do.
