sdf.Scale

sdf.Scale(sdf, scale)

Scale an SDF component-wise.

Note: Non-uniform scaling doesn’t produce exact SDFs. For uniform scaling, we can divide the distance by the scale factor to maintain correctness.

Parameters

Name	Type	Description	Default
sdf	SDF	The SDF to scale	required
scale	float | Array | Vector	Per-axis scale as Array [sx, sy, sz], Vector parameter, or float for uniform scaling	required

Methods

Name	Description
patch_fields	Forward the child’s patch fields through a uniform scale.
sdf	Pure function for component-wise scaling.

patch_fields

sdf.Scale.patch_fields()

Forward the child’s patch fields through a uniform scale.

Uniform scaling maps queries into the child frame as :meth:sdf does (p / s) and rescales the distances by s, keeping them exact. Non-uniform scaling warps each patch field differently along each axis — no exact decomposition — so it reports None.

sdf

sdf.Scale.sdf(child_sdf, p, scale)

Pure function for component-wise scaling.

Parameters

Name	Type	Description	Default
child_sdf		SDF function to scale	required
p	Array	Query point(s)	required
scale	Array	Scale vector [sx, sy, sz]	required

Returns

Name	Type	Description
	Array	Scaled SDF value
