nonlinear_transform

property Ruler.nonlinear_transform: str | None

An optional nonlinear transform, expressed as WGSL shader code, applied to the raw vertex positions.

The WGSL must define a function fn nonlinear_transform(pos: vec3f) -> vec3f { ... }. Alternatively, the given WGSL can be a single expression (without ‘;’) using pos (a vec3f) as an existing variable, in which case the code is wrapped in a function. E.g. vec3f(pos.x, pos.y*1.5, pos.z).

Note that the transform is applied to the raw geometry’s vertex positions of this object, and does not affect child objects.

Note that the transform is not taken into account in the calculation of bounding boxes.
