MeshBuilder class abstract

Builder for meshes.

Such meshes can contain different kinds of primitives, like quads or triangles. Both primitives support adding texture coordinates that are mapped to the corners of the primitives. See TriangleMeshBuilder and QuadMeshBuilder for more details.

Note: Normals cannot be set as they are not necessary when using the MeshBuilder.

Example how to build a cube using QuadMeshBuilder

Mesh? cube = MeshBuilder()
      .quad(Point3D(0.5, 0.5, 0.5),
            Point3D(-0.5, 0.5, 0.5),
            Point3D(0.5, -0.5, 0.5),
            Point3D(-0.5, -0.5, 0.5))
      .quad(Point3D(-0.5, 0.5, -0.5),
            Point3D(0.5, 0.5, -0.5),
            Point3D(-0.5, -0.5, -0.5),
            Point3D(0.5, -0.5, -0.5))
      .quad(Point3D(0.5, 0.5, -0.5),
            Point3D(0.5, 0.5, 0.5),
            Point3D(0.5, -0.5, -0.5),
            Point3D(0.5, -0.5, 0.5))
      .quad(Point3D(-0.5, 0.5, 0.5),
            Point3D(-0.5, 0.5, -0.5),
            Point3D(-0.5, -0.5, 0.5),
            Point3D(-0.5, -0.5, -0.5))
      .quad(Point3D(-0.5, 0.5, 0.5),
            Point3D(0.5, 0.5, 0.5),
            Point3D(-0.5, 0.5, -0.5),
            Point3D(0.5, 0.5, -0.5))
      .quad(Point3D(0.5, -0.5, 0.5),
            Point3D(-0.5, -0.5, 0.5),
            Point3D(0.5, -0.5, -0.5),
            Point3D(-0.5, -0.5, -0.5))
      .build();
