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 .NET. If you have concerns about any change listed,

#### Saving a 3D Model in Google Draco (.drc) format

The recent release of Aspose.3D for .NET API has added support of exporting 3D
models to Google Draco (.drc) formats. Developers can import any supported 3D
files, and then save in a Google Draco format.

This code example demonstrates how to export a 3D model to a Google Draco file
format:

**.NET, C#**

#### Adds Aspose.ThreeD.Formats.Draco.DracoCompressionLevel Enum

DracoCompressionLevel Enum helps in defining a compression level before saving
a 3D model in the Google Draco (.drc) format.

The following complete code of the Enum demonstrates various compression
levels with description:

**.NET, C#**

### Adds Aspose.ThreeD.Formats.Draco.DracoSaveOptions Class

DracoSaveOptions class allows developers to apply settings before saving a 3D
model in the Google Draco (.drc) format.

The following complete code of the class demonstrates all properties with
description:

**.NET, C#**

#### Adds Aspose.ThreeD.Formats.DracoFormat Class

This **Encode** method of the DracoFormat class allows developers to encode a
single mesh instead of the whole scene, which is more efficient.

The following complete code of the class demonstrates Encode method with
description:

**.NET, C#**

#### Encode a Mesh in Google Draco (.drc) Format

The Draco file does not have support for hierarchical scene, each .drc file
represents a mesh, so saving the scene will merge the whole scene into a
single mesh, which may lose information.

This code example demonstrates how to encode a Mesh in Google Draco (.drc)
format:

**.NET, C#**

#### Adds RotationMode member to Aspose.ThreeD.Entities.Frustum (Base class of
Camera and Light) Class

The default value is RotationMode.FixedTarget, makes it compatible with old
code in real time rendering.  
If the Frustum's rotation mode is FixedTarget, the orientation of the frustum
is specified by its LookAt property which is an absolute position in the world
space, in this mode you can always get different Direction property when its
position get changed.  
If the rotation mode is FixedDirection, frustum will no longer look at a
target, but keep the same direction (specified by its Direction property)
relative to its position, this is useful in designing tool like CAD or FPS
game, in this mode you can always get different LookAt property when its
position get changed.

This code example demonstrates how to set the rotation mode of a Camera:

**.NET, C#**

#### Adds Maginification member to Aspose.ThreeD.Entities.Camera Class

The default value is (1, 1), change this value can make the rendered image
scales in horizontal/vertical direction in orthographic camera.

This code example demonstrates how to set the rotation mode of a Camera:

**.NET, C#**
