v0.36

A coiled spring shape.

This is similar to helixSdf, but with the fixed height rather than infinite.

Parameters

• Axis:
  • X:
  • Y:
  • Z:
• Reverse:
• Radius: The radius of the spring, i.e. the distance of the spring from the center axis.
• Height: Height or length of the spring.
• Coils: The number of rotations in the spring. Larger values mean a tighter coil.
• Thickness: Thickness of the spring, used when no cross-section SDF is attached.
