sdf.Twist

sdf.Twist(sdf, strength, axis='z')

Twist deformation around an arbitrary axis.

Rotates points progressively based on their projection along the axis. Note: This produces an approximation, not an exact SDF.

Parameters

Name	Type	Description	Default
sdf		The SDF to twist	required
strength	float | Scalar	Twist amount (radians per unit length along axis)	required
axis	str | Array | Vector	Twist axis as Array [x, y, z], Vector, or string (‘x’, ‘y’, ‘z’). Defaults to ‘z’.	'z'

Methods

Name	Description
sdf	Pure function for twist deformation around an arbitrary axis.

sdf

sdf.Twist.sdf(child_sdf, p, strength, axis)

Pure function for twist deformation around an arbitrary axis.

Parameters

Name	Type	Description	Default
child_sdf		SDF function to twist	required
p	Array	Query point(s)	required
strength	float	Twist strength in radians per unit length along axis	required
axis	Array	Normalized twist axis [x, y, z]	required

Returns

Name	Type	Description
	Array	Twisted SDF value (approximate)
