Detailed Description
Level of detail signed field function.
Within the sphere, return the signed distance field of the sub-tree, outside of range, compute the distance to the sphere, otherwise interpolate between the two.
Constructor & Destructor Documentation
◆ SDFLodSphere()
|
explicit |
Create a level of detail node, with a sphere as a low level of detail shape.
- Parameters
-
n Sub-tree. c Center. ri,re Internal and external radius, the sphere shape will have the internal radius.
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 constant is λ=1.
Reimplemented from SDFNode.
◆ Memory()
|
virtual |
Return the size of a sub-tree.
Reimplemented from SDFNode.
