API changes

Added class aspose.threed.formats.JtLoadOptions

The new added JtLoadOptions allows you to instruct Aspose.3D to parse JT file’s meta data and save it as standard Aspose.3D’s properties.

Sample code

    opt = JtLoadOptions()
    opt.load_properties = True
    s = Scene.from_file("test.jt", opt)
    
    for prop in s.root_node.child_nodes[0].properties:
        print(f"{prop.name} = {prop.value}")

Added members to class aspose.threed.AxisSystem:

        def transform_to(self, target_system : aspose.threed.AxisSystem) -> aspose.threed.utilities.Matrix4:
                ...

        @classmethod
        def from_asset_info(clz, asset_info : aspose.threed.AssetInfo) -> aspose.threed.AxisSystem:
                ...

Sample code

The new added method allows you to create a transformation matrix to convert vector from one axis system to another axis system.

    scene = Scene.from_file("test.fbx")
    # Create a new axis sytem with up vector to +Y axis and front to +X axis.
    target = AxisSystem(CoordinateSystem.LEFT_HANDED, Axis.Y_AXIS, Axis.X_AXIS)
    # Create a transform matrix from scene's current axis sytem to our custom axis sytem
    transform = AxisSystem.from_asset_info(scene.assetInfo).transform_to(target)
    # Apply the transform to all geometries in the scene.
    PolygonModifier.apply_transform(scene.root_node, transform)

Added members to class aspose.threed.Entities.PolygonModifier:

        @classmethod
        def apply_transform(clz, node : aspose.threed.Node, transform : aspose.threed.utilities.Matrix4) -> None:
                ...

This new method allows you to apply a matrix to all control points of all descendent geometries.

Sample code

    scene = Scene.from_file("test.fbx")
    # Create a new axis sytem with up vector to +Y axis and front to +X axis.
    target = AxisSystem(CoordinateSystem.LEFT_HANDED, Axis.Y_AXIS, Axis.X_AXIS)
    # Create a transform matrix from scene's current axis sytem to our custom axis sytem
    transform = AxisSystem.from_asset_info(scene.assetInfo).transform_to(target)
    # Apply the transform to all geometries in the scene.
    PolygonModifier.apply_transform(scene.root_node, transform)
