This is a WIP. +2. I am not a graphics expert. +3. Stability is a non-goal. Keywords are likely to change in the interest of + performance and simplicity. + +Strawman FAQ + +1. Why create another toon shader? + +To deepen my understanding of lighting and to have a "simple" foundation on +top of which to create bespoke shader effects. lilToon and Poiyomi are both way +too fucking huge and complicated to fit my needs. + +2. Does it work? + +Sort of. I haven't implemented shadow receiving yet, so some water effects are +fucked up. + +3. Is it optimized? + +Sort of. I haven't benchmarked it. I know it's slower than Poiyomi. + +I use keywords on every feature so it shouldn't be obscenely bad. But I haven't +gotten to the point of like, deduplicating all computation and shoving as much +as possible into the vertex shader. So it's like. Sort of optimized. + +I'd like to strike a balance between performance and readability. Since it's +mostly for *my* use, I don't feel a need to make it totally optimal. + +4.
