Center FBX Model in Scene

Aspose.3D Product Family
1

Hello,

I am working on a little solution for loading a fbx file into Aspose. Center it in the scene and render the result to an png image.

Rendering the Image is no problem, but I can not find a way in the documentation for center the Object in the middel of the scene.
I know that my test file have a pivot point that is not in the center of the object.

In Unity I can get the boundingbox of the Mesh and calculate the different between the center of the boundingbox and the scene origin.

Can anybody tell me how to do that in Aspose.3D on the RootNode or direkt access the pivot point?

best regards

@JogiG,

The first node is not located at the world’s origin, so look at the origin will get the picture that the object is not in the center. You need to change the LookAt of camera from the Origin to the object will get the correct picture:
C#

var center = (boundingBox.Minimum + boundingBox.Maximum) * 0.5; 
camera.LookAt = center;

In order to get the bounding box from a geometry in object space coordinate system, please use the following lines of code.
C#

Geometry geometry = (new Sphere()).ToMesh(); 
var bbox = BoundingBox.FromGeometry(geometry);
