Detailed Description
Generic primitives. ,.
Constructor & Destructor Documentation
◆ SDFEuclidean()
|
explicit |
Create an Euclidean primitive.
Those primitives compute the signed Euclidean distance to a skeleton, thus the Lipschitz constant is 1.
Member Function Documentation
◆ Signed()
|
virtual |
Compute the signed Euclidean distance function.
By default compute the signed distance to the bounding box of the primitive.
- Parameters
-
p Point.
