We are pleased to announce the availability of new version 17.4.0 of Aspose.3D for .NET API. The new version of the API adds support of converting 3D models to the Google Draco (.drc) format. Developers can import any supported 3D file, and then export in DRC format. All 3D import formats are listed on this page: Import an Existing 3D File. The Draco saving options of the API allow to specify the compression level. This help topic shows how to specify Draco saving options: Use of the Google Draco (.drc) Save Options
Developers can also encode a Mesh in the Google Draco file. All other regular fixes and improvements are also included. Developers can install Aspose.3D Nuget package in their .NET applications because we publish each version as a NuGet package on the NuGet gallery. We recommend our clients upgrade old version of the Aspose.3D API to this latest one. For details on API fixes, please check Release Notes having a complete list of the features, enhancements and bug fixes.
Retrieve Mesh of a 3D Shape to Encode in Google Draco File
3D meshes are widely used in computer graphics applications for approximating 3D models. When representing complex shapes in raw data format, meshes consume a large amount of space. Using Aspose.3D for .NET API, developers can retrieve a mesh of any 3D shape, and then encode it in the Google Draco (.drc) file. This help topic will help to know the way of encoding a mesh in DRC file: Encoding a 3D Mesh in the Google Draco File
Improved Camera Movement and Magnification Support
Using Aspose.3D for .NET API, developers can already place a camera in 3D scene to define a view as narrated in this help topic: Take a Picture of 3D Model from the Camera. Developers can now find improvements in the Camera and Light movements with orthographic projection mode. There are two rotation modes as below:
FixedTarget mode is compatible with old code in real time rendering. The orientation of the Frustum (base class of Camera and Light) is specified by its LookAt property which is an absolute position in the world space, in this mode developers can always get different Direction property when its position get changed.
FixedDirection mode is useful in designing tools like CAD or FPS game. It will no longer look at a target, but keep the same direction (specified by its Direction property) relative to its position. In this mode, developers can always get different LookAt property when its position gets changed.
Developers can also zoom out camera to quickly magnify the view. The following source code demonstrates how to set the rotation and magnification of a Camera object:
// initialize a Camera object Camera camera = new Camera(); // set the rotation mode camera.RotationMode = RotationMode.FixedDirection; // Gets or sets the magnification used in orthographic camera camera.Magnification = new Vector2(2, 2);
Public API Changes
The following API changes in the new version are also worth noting:
DracoCompressionLevel Enum has been added. It helps in defining a compression level before saving a 3D model in the Google Draco (.drc) format.
DracoSaveOptions class has been added. It helps to apply settings before saving a 3D model in the Google Draco (.drc) format.
DracoFormat class has been added. It helps to encode the mesh of 3D shape to Draco mesh (raw data).
RotationMode member is added to Aspose.ThreeD.Entities.Frustum (Base class of Camera and Light) Class. It helps in Camera and Light movement.
Magnification member is added to Aspose.ThreeD.Entities.Camera Class. It helps in magnifying a view.
