Aspose.3D for .NET offre la possibilità di ruotare gli oggetti nello spazio 3D. Esistono tre modi per definire la rotazione dell’oggetto nello spazio 3D, angoli di Eulero, Quaternion e Custom Matrix, tutti supportati dalla classe
Transform.
TSR (Traduzione/Scaling/Rotazione) sono più comunemente utilizzati nello scenario 3D, abbiamo fornito una classe Transform per accedere a questi in Aspose.3D. Le trasformazioni affini includono:
- Traduzione
- Scalatura
- Rotazione
- Mappatura del taglio
- Spremi la mappatura
L’oggetto della classe
Mesh viene utilizzato nel codice. Possiamo Creare un oggetto classe Mesh come narrato lì.
