0012 QWls : Host-side WLS ICDF Texture Upload
0013 ============================================
0014
0015 Uploads the WLS inverse CDF array into a GPU texture and creates
0016 the device-side qwls struct with material mapping and time constants.
0017
0018 Follows the same pattern as QScint for scintillation ICDF textures.
