API Changes

We’ll migrate to System.Numerics in the future, and these changes are the first step to make our product compatible to System.Numerics:

Added members to class aspose.threed.entities.Mesh:

        # Perform Boolean operation on two meshes
        def do_boolean(op : BooleanOperation, a : Mesh, transformA : Optional[Matrix4], b : Mesh, transformB : Optional[Matrix4]) -> Mesh

        # Calculate the union of two meshes
        def union(a : Mesh, b : Mesh) -> Mesh

        # Calculate the difference of two meshes
        def difference(a : Mesh, b : Mesh) -> Mesh

        # Calculate the intersection of two meshes
        def intersect (Mesh a, Mesh b) -> Mesh

The new feature allows you to perform Boolean operations on two meshes, this feature is experimental and only works on manifold tri-mesh, unfortunately the meshes converted from our 3D primitives are not manifold tri-mesh, in the future this issue will be fixed.

        a = Mesh();
        a.control_points.append(Vector4(0, 0, 0));
        a.control_points.append(Vector4(1540, 0, 0));
        a.control_points.append(Vector4(1540, 70, 0));
        a.control_points.append(Vector4(0, 70, 0));
        a.control_points.append(Vector4(0, 0, -278.282));
        a.control_points.append(Vector4(1540, 70, -278.282));
        a.control_points.append(Vector4(1540, 0, -278.282));
        a.control_points.append(Vector4(0, 70, -278.282));
        a.create_polygon(0, 1, 2);
        a.create_polygon(2, 3, 0);
        a.create_polygon(4, 5, 6);
        a.create_polygon(5, 4, 7);
        a.create_polygon(6, 2, 1);
        a.create_polygon(6, 5, 2);
        a.create_polygon(5, 3, 2);
        a.create_polygon(5, 7, 3);
        a.create_polygon(7, 0, 3);
        a.create_polygon(7, 4, 0);
        a.create_polygon(4, 1, 0);
        a.create_polygon(4, 6, 1);

        b = Mesh();
        b.control_points.append(Vector4(2.04636e-12, 70, 50000));
        b.control_points.append(Vector4(2.04636e-12, -1.27898e-13, 50000));
        b.control_points.append(Vector4(1470, -1.27898e-13, 50000));
        b.control_points.append(Vector4(1540, 70, 50000));
        b.control_points.append(Vector4(2.04636e-12, 70, -28.2818));
        b.control_points.append(Vector4(1470, -1.27898e-13, 0));
        b.control_points.append(Vector4(2.04636e-12, -1.27898e-13, 0));
        b.control_points.append(Vector4(1540, 70, -28.2818));

        b.create_polygon(0, 1, 2);
        b.create_polygon(2, 3, 0);
        b.create_polygon(4, 5, 6);
        b.create_polygon(5, 4, 7);
        b.create_polygon(6, 2, 1);
        b.create_polygon(6, 5, 2);
        b.create_polygon(5, 3, 2);
        b.create_polygon(5, 7, 3);
        b.create_polygon(7, 0, 3);
        b.create_polygon(7, 4, 0);
        b.create_polygon(4, 1, 0);
        b.create_polygon(4, 6, 1);

        # calculate the union of two meshes
        union = a.union(b);

        # calculate the difference of two meshes 
        diff = a.difference(b);

        # calculate the intersection of two meshes
        intersect = a.intersect(b);
