Detailed Description
template<class T, class Meta, class BV, size_t K>
class FastMeshSDF< T, Meta, BV, K >
Signed distance function for a DCEL mesh. This class uses the full BVH representation.
Constructor & Destructor Documentation
◆ FastMeshSDF()
template<class T , class Meta , class BV , size_t K>
|
noexcept |
Full constructor. Takes the input mesh and creates the BVH.
- Parameters
-
[in] a_mesh Input mesh [in] a_build Specification of build method. Must be TopDown, Morton, or Nested.
Member Function Documentation
◆ getClosestFaces()
template<class T , class Meta , class BV , size_t K>
|
virtualnoexcept |
Get the closest faces to the input point.
This returns a list of candidate faces that are close to the input point. The returned argment consists of the faces and the unsigned distance to the face.
- Parameters
-
[in] a_point Input ponit [in] a_sorted Sort the output vector by distance or not. Closest goes first
- Returns
- List of candidate faces (potentially sorted)
