Detailed Description
Base planar signed distance node. ,.
Constructor & Destructor Documentation
◆ SDFNode2()
|
explicit |
Create a generic node.
Internally set Lipschitz bound to 1.0.
Member Function Documentation
◆ K()
|
virtual |
Return the Lipschitz constant of the node.
By default, nodes are considered as signed Euclidean distance functions, and the Lipschitz consistant is λ=1.
Reimplemented in SDFUnary2.
◆ Signed()
|
virtual |
Compute the signed distance.
- Parameters
-
p Point.
