iteratedTransform

Performs a transform multiple times, optionally reflecting across axes in between the steps.

This can be used to create KIFS fractals (kaleidoscopic iterated function systems).

Inputs

• definition_in: (required)
  • Coordinate Types: vec2 vec3
  • Context Types: Context MaterialContext CameraContext LightContext RayContext ParticleContext
  • Return Types: float vec4 Sdf
• Rotate Field: (optional) Optional field used to control rotation. The field is evaluated before each iteration, and the resulting value is added to the `Rotate` parameter. If the field uses 2D/3D coordinates, the current position is used. If the field uses 1D coordinates, it is passed `i / (n-1)`, where `i` is the loop iteration, and `n` is the total number of iterations.
