    • getMeshColor

      public java.awt.Color getMeshColor()
      Description copied from interface: Mesh
      Gives the mesh's color
      Specified by:
      getMeshColor in interface Mesh
      Returns:
      The color of the mesh

    • sdf

      public double sdf​(Vector3 position)
      Description copied from interface: Mesh
      The signed distance function for the mesh, which tells the mesh's distance to a point in 3D space
      Specified by:
      sdf in interface Mesh
      Parameters:
      position - The vector representation of the position of the point to measure the distance to
      Returns:
      The signed distance of the mesh to the point. Values > 0 indicate the point is outside the mesh, values = 0 are points on the surface, and values < 0 are points inside the mesh.
