      public Vector3f getScale(Vector3f storeResult)
      Copy the scale factors.
      Parameters:
      storeResult - storage for the result (modified if not null)
      Returns:
      the scale factor for each local axis (either storeResult or a new vector, not null)

    • getSubmesh

      public IndexedMesh getSubmesh(int index)
      Access the specified submesh.
      Parameters:
      index - the index of the desired submesh (in the order the submeshes were added, ≥0)
      Returns:
      the pre-existing instance (not null)

    • maxMin

      public void maxMin(Vector3f storeMaxima, Vector3f storeMinima)
      Find the maximum and minimum coordinates for each local axis among the scaled vertices in this mesh.
      Parameters:
      storeMaxima - storage for the maxima (not null, modified)
      storeMinima - storage for the minima (not null, modified)

    • setScale

      public void setScale(Vector3f scale)
      Alter the scale factors.
      Parameters:
      scale - the desired scale factor for each local axis (not null, no negative component, unaffected, default=(1,1,1))

    • split

      public CompoundMesh[] split(Triangle scaledTriangle)
      Attempt to divide this mesh into 2 meshes.
      Parameters:
      scaledTriangle - to define the splitting plane (in scaled coordinates, not null, unaffected)
      Returns:
      a pair of meshes, the first mesh generated by the plane's minus side and the 2nd mesh generated by its plus side; either mesh may be null, indicating an empty mesh
