Adición de transformación al nodo

Aspose.3D for Python via .NET ofrece rotar objetos en el espacio 3D. Hay tres formas de definir la rotación de un objeto en el espacio 3D, ángulos de Euler, Quaternion y Custom Matrix, todos ellos son compatibles con la clase Transform.

TSR (Traducción/Escalado/Rotación) se usan más comúnmente en el escenario 3D, proporcionamos una clase Transform para acceder a estos en Aspose.3D. Las transformaciones afín incluyen:

• Traducción
• Escala
• Rotación
• Mapeo de cizalla
• Mapeo de apretar

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

Girar por el cuaternión

from aspose.threed import FileFormat, Node, Scene
from aspose.threed.utilities import Quaternion, Vector3

#  For complete examples and data files, please go to https:# github.com/aspose-3d/Aspose.3D-for-.NET
#  Initialize scene object
scene = Scene()
#  Initialize Node class object
cubeNode = Node("cube")
#  Call Common class create mesh using polygon builder method to set mesh instance
mesh = Common.CreateMeshUsingPolygonBuilder()
#  Point node to the Mesh geometry
cubeNode.entity = mesh
#  Set rotation
cubeNode.transform.rotation = Quaternion.from_rotation(Vector3(0, 1, 0), Vector3(0.3, 0.5, 0.1))
#  Set translation
cubeNode.transform.translation = Vector3(0, 0, 20)
#  Add cube to the scene
scene.root_node.child_nodes.append(cubeNode)
#  The path to the documents directory.
output = "out"  + "TransformationToNode.fbx"
#  Save 3D scene in the supported file formats
scene.save(output, FileFormat.FBX7500ASCII)

Girar por ángulos de Euler

from aspose.threed import FileFormat, Node, Scene
from aspose.threed.utilities import Vector3

#  For complete examples and data files, please go to https:# github.com/aspose-3d/Aspose.3D-for-.NET
#  Initialize scene object
scene = Scene()
#  Initialize Node class object
cubeNode = Node("cube")
#  Call Common class create mesh using polygon builder method to set mesh instance
mesh = Common.CreateMeshUsingPolygonBuilder()
#  Point node to the Mesh geometry
cubeNode.entity = mesh
#  Euler angles
cubeNode.transform.euler_angles = Vector3(0.3, 0.1, -0.5)
#  Set translation
cubeNode.transform.translation = Vector3(0, 0, 20)
#  Add cube to the scene
scene.root_node.child_nodes.append(cubeNode)
#  The path to the documents directory.
output = "out"  + "TransformationToNode.fbx"
#  Save 3D scene in the supported file formats
scene.save(output, FileFormat.FBX7500ASCII)

Matriz de transformación personalizada

También podemos utilizar la matriz directamente:

from aspose.threed import FileFormat, Node, Scene
from aspose.threed.utilities import Matrix4

#  For complete examples and data files, please go to https:# github.com/aspose-3d/Aspose.3D-for-.NET
#  Initialize scene object
scene = Scene()
#  Initialize Node class object
cubeNode = Node("cube")
#  Call Common class create mesh using polygon builder method to set mesh instance
mesh = Common.CreateMeshUsingPolygonBuilder()
#  Point node to the Mesh geometry
cubeNode.entity = mesh
#  Set custom translation matrix
cubeNode.transform.transform_matrix = 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.root_node.child_nodes.append(cubeNode)
#  The path to the documents directory.
output = "out"  + "TransformationToNode.fbx"
#  Save 3D scene in the supported file formats
scene.save(output, FileFormat.FBX7500ASCII)
