AssetInfo

AssetInfo — Aspose.3D FOSS for Python API Reference

Overview

AssetInfo is a metadata container attached to a Scene via Scene.asset_info (or to a Node via Node.asset_info). It stores information about the file’s origin: the tool that created it, measurement units, creation/modification timestamps, and optional axis-system settings.

AssetInfo inherits from A3DObject.

Package: aspose.threed

from aspose.threed import AssetInfo

Constructor

Signature	Description
`AssetInfo()`	Constructs with all fields empty/default
`AssetInfo(name)`	Constructs with an optional object name

Properties

All fields are readable and writable properties.

Authoring and Identification

Name	Type	Description
`title`	`str`	Human-readable title of the asset
`subject`	`str`	Subject or topic of the asset
`author`	`str`	Name of the file’s author
`keywords`	`str`	Keywords associated with the asset
`revision`	`str`	Version or revision string
`comment`	`str`	Freeform comment or description
`copyright`	`str`	Copyright notice
`url`	`str`	Source URL or reference URI

Application Information

Name	Type	Description
`application_name`	`str`	Name of the authoring application (e.g., `"Blender"`)
`application_vendor`	`str`	Vendor of the authoring application
`application_version`	`str`	Version string of the authoring application

Timestamps

Name	Type	Description
`creation_time`	`datetime \| None`	Creation date/time of the asset
`modification_time`	`datetime \| None`	Last modification date/time

Units

Name	Type	Description
`unit_name`	`str`	Name of the measurement unit (e.g., `"centimeter"`, `"meter"`)
`unit_scale_factor`	`float`	Scale factor to convert from the file’s units to meters; defaults to `1.0`

Coordinate System (stub properties)

The following properties are present but return None in the current FOSS release. They are reserved for future axis-remapping support.

Name	Description
`coordinate_system`	Handedness convention (right-hand or left-hand)
`up_vector`	Which axis points up
`front_vector`	Which axis points forward
`axis_system`	Combined axis-system descriptor
`ambient`	Scene ambient colour

Example

from aspose.threed import Scene, AssetInfo
from datetime import datetime

# Load a scene and inspect its metadata
scene = Scene.from_file("model.fbx")
info = scene.asset_info

if info is not None:
    print(info.application_name)    # e.g. "Blender"
    print(info.unit_name)           # e.g. "centimeter"
    print(info.unit_scale_factor)   # e.g. 0.01

# Create metadata for an exported scene
out_scene = Scene()
out_info = AssetInfo()
out_info.title = "My Model"
out_info.author = "Alice"
out_info.application_name = "MyPipeline"
out_info.unit_name = "meter"
out_info.unit_scale_factor = 1.0
out_info.creation_time = datetime.now()
out_scene.asset_info = out_info

out_scene.save("output.glb")
