Detailed Description
Unary nodes.
Constructor & Destructor Documentation
◆ SDFUnary()
|
explicit |
Create an unary node.
Default Lipschitz constant and box are computed from the sub-tree.
- Parameters
-
n The sub-tree.
Member Function Documentation
◆ K()
|
virtual |
Return the local Lipschitz constant.
By default, binary nodes return the Lipschitz constant of their sub-tree.
- Parameters
-
b Box
Reimplemented from SDFNode.
◆ Nodes()
|
virtual |
Compute the number of nodes in the sub-tree.
Reimplemented from SDFNode.
◆ Signed()
|
virtual |
Compute the signed distance.
- Parameters
-
p Point.
Reimplemented from SDFNode.
Reimplemented in SDFBoundingBox, SDFBoundingSphere, SDFRound, SDFTaper, SDFTwist, SDFScale, SDFUniformScale, SDFRotate, SDFTranslate, SDFFrame, SDFPlanarSymmetry, SDFVoxelize, SDFTriplanar, SDFNoise, SDFTurbulence, SDFWarpTurbulence, SDFAddSphere, SDFLodSphere, SDFClone, and SDFCloneRevolution.
