Henrik Rydgård 0eede05f5f Implement fragment shader depth clamp and min/max discard. Slow on some hardware, but it's a fallback. 2026-05-30 19:07:59 +02:00
Henrik Rydgård de266c3d6c Add the appropriate epsilons to cull distance. Fixes the NBA issue. 
It's a bit odd that this draw doesn't go through software transform
though.

Henrik Rydgård d243737c11 Revert "Convert the pre-rotation to just the matrix multiplication." 
After the previous commit, the optimization is no longer needed, and
unnecessarily bloats the uniform buffer.

This reverts commit 62bcb1785e809649ba88b49e24c5217f457fa040.

Chris Healyandcphealy 9ed5dcdc27 GPU: Use inversesqrt for light distance and half-vector calculations 
Replace length()/normalize() with inversesqrt() pattern for better
performance on mobile GPUs. The inversesqrt instruction is a single
hardware operation, while length() requires sqrt(dot()) and normalize()
requires inversesqrt internally plus a multiply.

Changes:
1. Light distance calculation:
   Before: distance = length(toLight); toLight /= distance;
   After:  distSq = dot(toLight, toLight);
           invDist = inversesqrt(distSq);
           distance = distSq * invDist;
           toLight *= invDist;

2. Specular half-vector normalization:
   Before: ldot = dot(normalize(toLight + vec3(0,0,1)), worldnormal);
   After:  halfVec = toLight + vec3(0,0,1);
           halfInvLen = inversesqrt(dot(halfVec, halfVec));
           ldot = dot(halfVec, worldnormal) * halfInvLen;

Also reuses distSq in attenuation calculation to avoid recomputing
distance*distance.

Offline shader compiler results (vertex shader with 4-light ubershader):

Mali (malioc):
  G31 (Bifrost): 44.90 -> 40.50 cycles (-9.8%)
  G52 (Bifrost): 14.97 -> 13.50 cycles (-9.8%)
  G310 (Valhall): 13.88 -> 12.88 cycles (-7.2%)
  G57 (Valhall):  7.60 ->  6.97 cycles (-8.3%)

PowerVR (Profiling Compilers):
  Series 8 GE8300: 322 -> 302 ALU cycles (-6.2%)
  Series 9 GM9445: 296 -> 280 ALU cycles (-5.4%)
  Series B BXM:    560 -> 540 instructions (-3.6%)
