3D场景的比例几何

单个3D节点或3D场景的所有节点的缩放几何形状

开发人员只能缩放3D节点的几何形状或3D场景的所有节点。为了实现这一点，开发人员可以调用PolygonModifier类实例的多个规模成员。这是缩放所有节点或单个节点的代码示例:

Python

from aspose.threed.utilities import Vector3
from aspose.threed.entities import PolygonModifier, Box
from aspose.threed import Scene

# scale the model in huge-scene.obj by 0.01 and save it to another file:

scene = Scene.from_file("huge-scene.obj")

# create a Box instance

box = scene.root_node.create_child_node("box", Box())

# scale geometries of a single node

PolygonModifier.scale(box, Vector3(0.01));

# scale geometries of all nodes

PolygonModifier.scale(scene, Vector3(0.01));

scene.save("scaled-scene.obj", FileFormat.WAVEFRONT_OBJ)
