Houdini 13.0 Nodes

interface version 1

Generates a superellipse shape.

This operator creates a superellipse shape.

  • Superellipse shapes with different exponent values.

As quoted by the Danish poet and scientist Piet Hein (1905-1996):

"Man is the animal that draws lines which he himself then stumbles over. In the whole pattern of civilization there have been two tendencies, one toward straight lines and rectangular patterns and one toward circular lines. There are reasons, mechanical and psychological, for both tendencies. Things made with straight lines fit well together and save space. And we can move easily -- physically or mentally -- around things made with round lines. But we are in a straitjacket, having to accept one or the other, when often some intermediate form would be better. (...) The super-ellipse solved the problem. It is neither round nor rectangular, but in between. Yet it is fixed, it is definite -- it has a unity."

Parameters

Plane of creation.

Primirive Type

Type of the generated curve.

Radius

X and Y radii of the superellipse.

Center

Location of the center of the superellipse.

To Do

  • Properly fix the non-zero coord component bug

  • The “primitive” geometry type doesn’t worka and should be removed
