公共API和向后不兼容的更改

请参阅对公共API所做的任何更改的列表，如添加、重命名、删除或不推荐使用的成员，以及对Aspose.3D for Java所做的任何非向后兼容的更改。如果您对列出的任何更改有疑问，请在Aspose.3D支持论坛。

添加了新的文件格式HTML5/ASPOSE3D_WEB

 /**

\* Aspose.3D Web format.

*/

public static final FileFormat ASPOSE3D_WEB;

/**

\* HTML5 File

*/

public static final FileFormat HTML5;

当您将场景导出到HTML5文件时，实际上会有3个文件，一个HTML文件，一个Aspose3的DWeb文件 (*.a3dw) 和一个渲染的JavaScript文件，您只能通过指定Aspose3的DWeb作为导出类型来导出a3dw文件，并在您自己的HTML页面中重用javascript文件。

示例代码:

 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);

由于浏览器的安全限制，导出的HTML文件不能直接打开，您需要通过网络服务器打开它，如果您安装了python3，您可以在导出目录中的命令行中启动网络服务器

 python3 -m http.server

然后打开它http:// localhost:8000/test.html。web渲染器使用WebGL2，您可以使用https://get.webgl.org/webgl2/检查您的浏览器是否支持它。

添加了新类com.aspose.threed.HTML5SaveOptions

这允许您自定义导出的3D HTML页面

示例代码:

 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);

在类com.aspose.threed.IOConfig中添加了新的属性文件格式

 /**

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

 */

public FileFormat getFileFormat();

在类com.aspose.threed.Node中添加了新方法evalateglobaltransform

 /**

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

 * @param withGeometricTransform Whether the geometric transform is needed.

 */

public Matrix4 evaluateGlobalTransform(boolean withGeometricTransform);

Node.GlobalTransform.TransformMatrix之间的区别在于，它允许您获得具有几何变换的变换矩阵，该变换矩阵仅影响附加实体并保持子节点不受影响。

在类com.aspose.threed中添加了新的吸气剂/setter getGeometricTranslation/setGeometricScaling/setGeometricRotation/setgeometrication

 /**

 * 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);

示例代码:

 Node n = new Node();

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

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

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

第一个print语句将输出包含几何变换的变换矩阵，而第二个则不输出。
