I am writing a WebGL2 fragment shader for thin-film holographic foil iridescence. I plan to compute spectral color interference directly in sRGB space and output outColor directly without gamma correction. Is this approach correct for optical film math?
| Checked | Without skill | With skill |
|---|---|---|
| The response recommends computing thin-film optical interference calculations in linear color space. | Passed | Passed |
| The fragment shader applies gamma encoding to the computed linear color using pow(color, vec3(1.0 / 2.2)) before setting output color. | Missed | Passed |
