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 file formats HTML5/ASPOSE3D_WEB

 /**

\* Aspose.3D Web format.

*/

public static final FileFormat ASPOSE3D_WEB;

/**

\* HTML5 File

*/

public static final FileFormat HTML5;

When you export the scene into HTML5 file, there will be actually 3 files, an HTML file, an Aspose3DWeb file(*.a3dw), and a rendered JavaScript file, you can only export the a3dw file by specifying the Aspose3DWeb as the export type, and reuse the javascript file within your own HTML page.

Sample code:

 Scene scene = new Scene();

Node node = scene.getRootNode().createChildNode(new Cylinder());

LambertMaterial mat = new LambertMaterial();

mat.setDiffuseColor(new Vector3(0.34,0.59, 0.41));

node.setMaterial(mat);

Light light = new Light();

light.setLightType(LightType.POINT);

scene.getRootNode().createChildNode(light).getTransform().setTranslation(10, 0, 10);

scene.save("test.html", FileFormat.HTML5);

Due to the browser’s security limits, the exported HTML file cannot be opened directly, you need to open it through a web server, if you have python3 installed, you can start the webserver in the command line in the exported directory

 python3 -m http.server

Then open it http://localhost:8000/test.html. The web renderer uses WebGL2, you can use https://get.webgl.org/webgl2/ to check if your browser supports it or not.

Added new class com.aspose.threed.HTML5SaveOptions

This allows you to customize the exported 3D HTML page

Sample code:

 Scene scene = new Scene();

Node node = scene.getRootNode().createChildNode(new Cylinder());

LambertMaterial mat = new LambertMaterial();

mat.setDiffuseColor(new Vector3(0.34,0.59, 0.41));

node.setMaterial(mat);

Light light = new Light();

light.setLightType(LightType.POINT);

scene.getRootNode().createChildNode(light).getTransform().setTranslation(10, 0, 10);

HTML5SaveOptions opt = new HTML5SaveOptions();

opt.setShowGrid(false); // Turn off the grid

opt.setShowUI(false); //Turn off the user interface

scene.save("test.html", FileFormat.HTML5);

Added new property FileFormat in class com.aspose.threed.IOConfig

 /**

 * Gets the file format that specified in current Save/Load option.

 */

public FileFormat getFileFormat();

Added new method evaluateGlobalTransform in class com.aspose.threed.Node

 /**

 * Evaluate the global transform, include the geometric transform or not.

 * @param withGeometricTransform Whether the geometric transform is needed.

 */

public Matrix4 evaluateGlobalTransform(boolean withGeometricTransform);

The difference between Node.GlobalTransform.TransformMatrix is that it allows you to get a transformation matrix with a geometric transform, which only affects the attached entity and keeps the child nodes unaffected.

Added new getter/setter getGeometricTranslation/setGeometricTranslation/getGeometricScaling/setGeometricScaling/getGeometricRotation/setGeometricRotation in class com.aspose.threed.Transform

 /**

 * Gets the geometric translation.

 * Geometric transformation only affects the entities attached and leave the child nodes unaffected.

 * It will be merged as local transformation when you export the geometric transformation to file types that does not support it.

 */

public Vector3 getGeometricTranslation();

/**

 * Sets the geometric translation.

 * Geometric transformation only affects the entities attached and leave the child nodes unaffected.

 * It will be merged as local transformation when you export the geometric transformation to file types that does not support it.

 * @param value New value

 */

public void setGeometricTranslation(Vector3 value);

/**

 * Gets the geometric scaling.

 * Geometric transformation only affects the entities attached and leave the child nodes unaffected.

 * It will be merged as local transformation when you export the geometric transformation to file types that does not support it.

 */

public Vector3 getGeometricScaling();

/**

 * Sets the geometric scaling.

 * Geometric transformation only affects the entities attached and leave the child nodes unaffected.

 * It will be merged as local transformation when you export the geometric transformation to file types that does not support it.

 * @param value New value

 */

public void setGeometricScaling(Vector3 value);

/**

 * Gets the geometric euler rotation(measured in degree).

 * Geometric transformation only affects the entities attached and leave the child nodes unaffected.

 * It will be merged as local transformation when you export the geometric transformation to file types that does not support it.

 */

public Vector3 getGeometricRotation();

/**

 * Sets the geometric euler rotation(measured in degree).

 * Geometric transformation only affects the entities attached and leave the child nodes unaffected.

 * It will be merged as local transformation when you export the geometric transformation to file types that does not support it.

 * @param value New value

 */

public void setGeometricRotation(Vector3 value);

Sample code:

 Node n = new Node();

n.getTransform().setGeometricTranslation(new Vector3(10, 0, 0));

System.out.println(n.evaluateGlobalTransform(true));

System.out.println(n.evaluateGlobalTransform(false));

The first print statement will output the transform matrix that includes the geometric transformation while the second one will not.
