Generate UV

Generate UV

Aspose.3D for .NET offers PolygonModifier class which exposes GenerateUV method, with which you can manually generate UV and associate it with the mesh. Following code snippet shows complete functionality to generate and associate it:

// For complete examples and data files, please go to https://github.com/aspose-3d/Aspose.3D-for-.NET
Scene scene = new Scene();
//since all primitive entities in Aspose.3D will have builtin UV generation
//here we manually remove it to assume we have a mesh without UV data
var mesh = (new Box()).ToMesh();
mesh.VertexElements.Remove(mesh.GetElement(VertexElementType.UV));
//then we can manually generate UV for it
var uv = PolygonModifier.GenerateUV(mesh);
//generated UV data is not associated with the mesh, we should manually do this
mesh.AddElement(uv);
//put it to the scene
var node = scene.RootNode.CreateChildNode(mesh);
//then save it
scene.Save("Aspose.obj");
