Aspose.3D for Python via .NET 22.7 Release Notes
This page contains release notes information for Aspose.3D for .NET 22.7.
Improvements and Changes
| Key | Summary | Category |
|---|---|---|
| THREEDNET-1166 | Switch to USDZ as HTML5’s default internal format | New Feature |
| THREEDPYTHON-17 | Mesh’s control points are not exposed in python version | Improvement |
API changes
The old A3DW format was used as HTML5’s internal format, now it’s obsoleted and replaced by the USDZ, which can provide more features and extensibility.
Since 22.7 the aspose.threed.entities.Mesh will have a property control_points, it can be used to manually define the vertices of the Mesh.
Sample code:
from aspose.threed.entities import Mesh
from aspose.threed.utilities import Vector4
controlPoints = [
Vector4( -5.0, 0.0, 5.0, 1.0),
Vector4( 5.0, 0.0, 5.0, 1.0),
Vector4( 5.0, 10.0, 5.0, 1.0),
Vector4( -5.0, 10.0, 5.0, 1.0),
Vector4( -5.0, 0.0, -5.0, 1.0),
Vector4( 5.0, 0.0, -5.0, 1.0),
Vector4( 5.0, 10.0, -5.0, 1.0),
Vector4( -5.0, 10.0, -5.0, 1.0)
]
# Initialize mesh object
mesh = Mesh();
# Add control points to the mesh
for pt in controlPoints:
mesh.control_points.append(pt)
# Create polygons to mesh
# Front face (Z+)
mesh.create_polygon(0, 1, 2, 3);
# Right side (X+)
mesh.create_polygon(1, 5, 6, 2);
# Back face (Z-)
mesh.create_polygon(5, 4, 7, 6);
# Left side (X-)
mesh.create_polygon(4, 0, 3, 7);
# Bottom face (Y-)
mesh.create_polygon(0, 4, 5, 1);
# Top face (Y+)
mesh.create_polygon(3, 2, 6, 7);
