Original Twigl

Available for the Yohei archive. This uses the compact source from the linked post with Twigl’s native globals and helpers.

Original speed 0.30

Equation Preview

A neutral sampler for the selected base function. It skips Deep Field’s coordinate maps, extra detail, feedback, and color treatment.

About this field

The Structure controls replace the actual coordinate map, surface function, and way each ray step is accumulated. They change the shader's underlying field—not just its treatment after the fact.
