Aspose.3D for .NET logo

We are pleased to announce the availability of new version 18.3.0 of Aspose.3D for .NET API. The new version 18.3 of the API has been released with the support of retrieving the bounding box of entities in 3D model. Developers can find improvement on applying transparency to the materials as well as the compatibility support among 3D formats with new APIs. The recent version 18.3 also covers enhancements and regular bug fixes. We recommend our clients to incorporate the latest upgrade of Aspose.3D for .NET API to take benefit of improved functionality and bug fixes.

Apply Texture-Transparency with Per-Pixel Alpha Channel

With the help of Aspose.3D for .NET API, developers can apply a material using per-pixel alpha channel defined in the diffuse/albedo texture. In order to achieve this, we have added Alpha and AlphaSource members. These members make it compatible with texture-transparency in 3D formats like U3D/FBX and these are also supported in Aspose.3D API renderer, since LambertMaterial, PhongMaterial, and PbrMaterial classes have transparency factors.

// define a box node with alpha channel defined in albedo texture:
var node = new Node()
    Material = new PbrMaterial()
        AlbedoTexture = new Texture()
            AlphaSource = AlphaSource.PixelAlpha,
            Alpha = 1,
            FileName = "window.tga"
     Entity = new Box()

Retrieve Bounding Box of 3D Entities using C#

With the recent version 18.3 of Aspose.3D for .NET API, developers can retrieve a bounding box of 3D entities. The GetBoundingBox method has been added to the base Entity class:

var box = new Box();
BoundingBox bbox = box.GetBoundingBox();
