Kernel

Differentiable

Computes the closest point on the warp.Mesh with identifier id to the given point in space.

Identifies the sign of the distance (inside/outside) using the angle-weighted pseudo normal. This approach to sign determination is robust for well conditioned meshes that are watertight and non-self intersecting. It is also comparatively fast to compute.

param id:

The mesh identifier

param point:

The point in space to query

param max_dist:

Mesh faces above this distance will not be considered by the query

param epsilon:

Epsilon treating distance values as equal, when locating the minimum distance vertex/face/edge, as a fraction of the average edge length, also for treating closest point as being on edge/vertex default 1e-3
