Aspose.3D for .NET propose de faire pivoter des objets dans un espace 3D. Il existe trois façons de définir la rotation de l’objet dans l’espace 3D, les angles d’Euler, Quaternion et la matrice personnalisée, toutes sont supportées par la classe
Transform
.
Les TSR (Translation/Scaling/Rotation) sont les plus couramment utilisés dans le scénario 3D, nous avons fourni une classe Transform
pour y accéder dans Aspose.3D. Les transformations affines comprennent:
- Traduction
- Mise à l’échelle
- Rotation
- Cartographie de cisaillement
- Cartographie à presser
L’objet de classe
Mesh
est utilisé dans le code. Nous pouvons Créer un objet de classe Mesh tel que raconté là-bas.
