API changes

Most changes in 21.9 are PointCloud related, added XYZ/PCD support for PointCloud, fixed Point Cloud export in PLY, added PointCloud import/export/rendering support in A3DW/HTML.

Added new method to class com.aspose.threed.PointCloud:

    /**
     * Create a new point cloud instance from a geometry object.
     * Density is the number of points per unit triangle(Unit triangle are the triangle with maximum surface area from the mesh)
     * @param g Mesh or other geometry instance
     * @param density Number of points per unit triangle
     */
    public static PointCloud fromGeometry(Geometry g, int density);

The new FromGeometry allows you to specify the density of distributed points in the geometry’s triangles.

Sample code:

        var prim = new Torus();
        var pc = PointCloud.fromGeometry(prim.toMesh(), 50);
        var s = new Scene(pc);
        s.save("point-cloud.glb", FileFormat.GLTF2_BINARY);

Added new formats to class com.aspose.threed.FileFormat:

    /**
     * Xyz point cloud file
     */
    public static final FileFormat XYZ;
    /**
     * PCL Point Cloud Data file in ASCII mode
     */
    public static final FileFormat PCD;
    /**
     * PCL Point Cloud Data file in Binary mode
     */
    public static final FileFormat PCD_BINARY;

Sample code:

        var prim = new Torus();
        var pc = PointCloud.fromGeometry(prim.toMesh(), 50);
        var s = new Scene(pc);
        s.save("point-cloud.glb", FileFormat.PCD);
