Quest User Documentation

The Quest component of Axom provides several spatial operations and queries on a mint::Mesh.

• Operations
  • Read a surface mesh<reading-mesh> from an STL file
  • Check for some common mesh errors; deduplicate vertices<check-and-repair>
    • vertex welding: merge vertices closer than a specified distance "epsilon"
    • find self-intersections and degenerate triangles in a surface mesh
    • watertightness test: is a surface mesh a watertight manifold?
• Point queries
  • Surface mesh point queries in C<surface-query-c> or in C++<surface-query-cpp>
    • in/out query: is a point inside or outside a surface mesh?
    • signed distance query: find the minimum distance from a query point to a surface mesh
  • Point in cell query<point-in-cell>: for a query point, find the cell of the mesh that holds the point and the point's isoparametric coordinates within that cell
  • All nearest neighbors<all-nearest>: given a list of point locations and regions, find all neighbors of each point in a different region
