| ccl_device_inline Spectrum iridescence_lookup_sensitivity | ( | const float | OPD, |
| const float | shift ) |
Evaluate the sensitivity functions for the Fourier-space spectral integration. The code here uses the Gaussian fit for the CIE XYZ curves that is provided in the reference implementation. For details on what this actually represents, see the paper. In theory we should pre-compute the sensitivity functions for the working RGB color-space, remap them to be functions of (light) frequency, take their Fourier transform and store them as a LUT that gets looked up here. In practice, using the XYZ fit and converting the result from XYZ to RGB is easier.
