WaterWaveCount

Remarks

Quantised, and it is the permutation axis — [35 § D7](../../docs/plan/35-water.md#d7-waves-are-a-spectrum-summed-as-gerstner-and-the-fft-is-deferred-with-arithmetic). A sea state gaining one wave must not compile a shader, so the count a document types rounds up to one of three and the vertex stage has three variants rather than thirty. [31 § D6](../../docs/plan/31-terrain-grass-and-trees.md)'s trick, unchanged.

⚠ It is also what keeps the two evaluators the same shape. A dynamic loop on the CPU and an unrolled one on the GPU is how two implementations of one function start to differ in the last bits — see [§ D2](../../docs/plan/35-water.md#d2-one-evaluator-two-hosts-and-the-seam-is-a-test).
