Public API and Backwards Incompatible Changes

See the list of any changes made to the public API such as added, renamed, removed or deprecated members as well as any non-backward compatible change made to Aspose.3D for Java. If you have concerns about any change listed, please raise it on the Aspose.3D support forum.

Added new getter/setter PointCloud in class com.aspose.threed.ObjSaveOptions

 /**

 * Gets the flag whether the exporter should export the scene as point cloud(without topological structure), default value is false

 */

public boolean getPointCloud();

/**

 * Sets the flag whether the exporter should export the scene as point cloud(without topological structure), default value is false

 * @param value New value

 */

public void setPointCloud(boolean value);

Sample code to generate a point cloud of Sphere in obj format.

 Scene scene = new Scene(new Sphere());

ObjSaveOptions opt = new ObjSaveOptions();

opt.setPointCloud(true);

scene.save("sphere.obj", opt);

Added new methods createPolygon com.aspose.threed.Mesh

 /**

 * Create a polygon with 4 vertices(quad)

 * @param v1 Index of the first vertex

 * @param v2 Index of the second vertex

 * @param v3 Index of the third vertex

 * @param v4 Index of the fourth vertex

 */

public void createPolygon(int v1, int v2, int v3, int v4);

/**

 * Create a polygon with 3 vertices(triangle)

 * @param v1 Index of the first vertex

 * @param v2 Index of the second vertex

 * @param v3 Index of the third vertex

 */

public void createPolygon(int v1, int v2, int v3);

Sample code.

 Mesh mesh = new Mesh();

mesh.createPolygon(new int[] { 0, 1, 2 }); //The old CreatePolygon needs to create a temporary array for holding the face indices

mesh.createPolygon(0, 1, 2); //The new overloads doesn't need extra allocation, and it's optimized internally.

The newly added methods createPolygon allow you to create a triangle or quad without allocating extra memory, it’s highly optimized internally.

Removed old public field prettyPrint in class com.aspose.threed.GLTFSaveOptions

This was removed and replaced by property with the same name.

Added new getter/setter PrettyPrint in class com.aspose.threed.GLTFSaveOptions

 /**

\* The JSON content of GLTF file is indented for human reading, default value is false

*/

public boolean getPrettyPrint();

/**

\* The JSON content of GLTF file is indented for human reading, default value is false

\* @param value New value

*/

public void setPrettyPrint(boolean value);

The old prettyPrint was a public field, and it’s been replaced by property for consistent.

Sample Code.

 Scene scene = new Scene(new Sphere());

GLTFSaveOptions opt = new GLTFSaveOptions(FileFormat.GLTF2);

//opt.prettyPrint = true; //Old code

opt.setPrettyPrint(true); //Use setter to change this configuration.

scene.save("sphere.gltf", opt);
