#include <MeshToVolume.h>

Detailed Description

Convert polygonal meshes that consist of quads and/or triangles into signed or unsigned distance field volumes.

Note: Requires a closed surface but not necessarily a manifold surface. Supports surfaces with self intersections and degenerate faces and is independent of mesh surface normals.

Expected interface for the MeshDataAdapter class

struct MeshDataAdapter {
  size_t polygonCount() const;        // Total number of polygons
  size_t pointCount() const;          // Total number of points
  size_t vertexCount(size_t n) const; // Vertex count for polygon n
  // Return position pos in local grid index space for polygon n and vertex v
  void getIndexSpacePoint(size_t n, size_t v, openvdb::Vec3d& pos) const;
};

Parameters

mesh	mesh data access class that conforms to the MeshDataAdapter interface
transform	world-to-index-space transform
exteriorBandWidth	exterior narrow band width in voxel units
interiorBandWidth	interior narrow band width in voxel units (set to std::numeric_limits<float>::max() to fill object interior with distance values)
flags	optional conversion flags defined in `MeshToVolumeFlags`
polygonIndexGrid	optional grid output that will contain the closest-polygon index for each voxel in the narrow band region
interiorTest	function `Coord -> Bool` that evaluates to true inside of the mesh and false outside, for more see evaluateInteriortest
interiorTestStrat	determines how the interiorTest is used, see InteriorTestStrategy
