Lägga till omvandling i noden

Aspose.3D for .NET erbjuder att rotera objekt i 3D mellanslag. Det finns tre sätt att definiera objekts rotation i 3D utrymme, Euler vinklar, Quaternion och Custom Matrix, Alla stöds av klassen Transform.

TSR (översättning/skalning/rotation) används oftast i 3D scenario, vi tillhandahöll en klass Transform för att komma åt dessa i Aspose. 3D. Affina transformationer omfattar:

• Översättning
• Skalning
• Rotationer
• Skjut avbildning
• Tryck på kartläggning

The Mesh class object is being used in the code. We can create a Mesh class object as narrated there.

Rotera med kvittering

// For complete examples and data files, please go to https://github.com/aspose-3d/Aspose.3D-for-.NET
// Initialize scene object
Scene scene = new Scene();

// Initialize Node class object
Node cubeNode = new Node("cube");

// Call Common class create mesh using polygon builder method to set mesh instance 
Mesh mesh = Common.CreateMeshUsingPolygonBuilder(); 
           
// Point node to the Mesh geometry
cubeNode.Entity = mesh;
// Set rotation
cubeNode.Transform.Rotation = Quaternion.FromRotation(new Vector3(0, 1, 0), new Vector3(0.3, 0.5, 0.1));            
// Set translation
cubeNode.Transform.Translation = new Vector3(0, 0, 20);            
// Add cube to the scene
scene.RootNode.ChildNodes.Add(cubeNode);            
   
// Save 3D scene in the supported file formats
scene.Save("TransformationToNode.fbx");

Rotera med Euler vinklar

// For complete examples and data files, please go to https://github.com/aspose-3d/Aspose.3D-for-.NET
// Initialize scene object
Scene scene = new Scene();

// Initialize Node class object
Node cubeNode = new Node("cube");

// Call Common class create mesh using polygon builder method to set mesh instance 
Mesh mesh = Common.CreateMeshUsingPolygonBuilder(); 
           
// Point node to the Mesh geometry
cubeNode.Entity = mesh;
// Euler angles
cubeNode.Transform.EulerAngles = new Vector3(0.3, 0.1, -0.5);            
// Set translation
cubeNode.Transform.Translation = new Vector3(0, 0, 20);            
// Add cube to the scene
scene.RootNode.ChildNodes.Add(cubeNode);            

// Save 3D scene in the supported file formats
scene.Save("TransformationToNode.fbx");

Egen omvandlingsmatris

Vi kan också använda Matrix direkt:

// For complete examples and data files, please go to https://github.com/aspose-3d/Aspose.3D-for-.NET
// Initialize scene object
Scene scene = new Scene();

// Initialize Node class object
Node cubeNode = new Node("cube");

// Call Common class create mesh using polygon builder method to set mesh instance 
Mesh mesh = Common.CreateMeshUsingPolygonBuilder(); 
           
// Point node to the Mesh geometry
cubeNode.Entity = mesh;
// Set custom translation matrix
cubeNode.Transform.TransformMatrix = new Matrix4(
1, -0.3, 0, 0,
0.4, 1, 0.3, 0,
0, 0, 1, 0,
0, 20, 0, 1
);        
// Add cube to the scene
scene.RootNode.ChildNodes.Add(cubeNode);            
   
// Save 3D scene in the supported file formats
scene.Save("TransformationToNode.fbx");
