And the number of terms you need to get a good approximation is related to the frequency. Low frequency signals like lighting work well.

- lukko 6mo agothis is all so interesting.. Are there any particular functions / parameters that are typically used, that say replicates 3 point light setups? I guess at a certain point the number of terms becomes so large that it makes sense to just use a cube map?
- groundzeros2015 6mo agoIn the era im familiar with (ps3, 360) everyone used the first 9 coefficients. You can read the original Ramamoorthi paper for better theory applied to lighting. But yes it’s an approximation. If you have a ton of terms it looks like a bitmap like you said.
