v0.40

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).

Swap Inputs

Swaps the order of the inputs. This is only relevant for “diff” modes.
Blend Radius

The size of the blending region.
Blend Number

For stair and column modes, this controls how many steps are used in the blending regions.
Blend Offset

Inputs

  • definition_in: (required)
    • Coordinate Types: vec2 vec3
    • Context Types: Context MaterialContext CameraContext LightContext RayContext ParticleContext VertexContext PixelContext
    • Return Types: float vec4 Sdf
    • Supports Variables: step normstep
  • 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.
