Interface TriangleMesh

All Superinterfaces:
Iterable<Triangle3d>
public interface TriangleMesh extends Iterable<Triangle3d>
Represents a mesh made of triangles. TriangleMesh is also an Iterable of triangles. Since this is an iterable, using iterating over it from multi threads at the same time is not safe, since the iterations conflict with each other. For multi-threaded access, be sure to call toTriangleCollection() or toPointCollection() and use those collections.

    • isInsideOut

      boolean isInsideOut()
      Returns true if the closed TriangleMesh is inside-out, meaning that the normals of the surface triangles point inwards instead of outwards. An inside-out mesh is produced when its triangles are oriented clockwise when looking from the outside, instead of being oriented counter-clockwise. When a clockwise mesh is joined to a counter-clockwise mesh, their volume is subtracted instead of added, and some of the mesh algorithms may return unintuitive or incorrect results. The result of this method is meaningful only for closed meshes that have self-consistent triangle orientation.
      Returns:
      true if the TriangleMesh surface is oriented inside-out

This method can be used to retrieve a corrected version of an inside-out mesh resulting from a transformation that did not preserve the orientation of the triangles in the mesh.
      Returns:
      the flipped version of this TriangleMesh

      9.10.2

      Returns the total volume enclosed by this TriangleMesh. This method will produce a meaningful result only if the TriangleMesh is closed and does not contain intersecting solids.
      Returns:
      the total volume enclosed by this TriangleMesh
      Since:
      9.10.2
