Installation

Installation of Aspose.3D FOSS for Python

Aspose.3D FOSS for Python is distributed as a pure-Python package on PyPI. There are no native extensions to compile, no system libraries to install, and no Microsoft Office or other third-party runtime required.

Prerequisites

1. Install via pip (Recommended)

The simplest way to install Aspose.3D FOSS is directly from PyPI:

pip install aspose-3d-foss

pip will download and install the package and record it in your environment. No post-install configuration is needed.

To install a pinned version for reproducible builds:

pip install aspose-3d-foss==26.1.0

2. Set Up a Virtual Environment (Recommended for Projects)

Using a virtual environment keeps the library isolated from other Python projects and avoids version conflicts.

Create and activate a virtual environment:

##Create the environment
python -m venv .venv

##Activate on Linux / macOS
source .venv/bin/activate

##Activate on Windows (Command Prompt)
.venv\Scripts\activate.bat

##Activate on Windows (PowerShell)
.venv\Scripts\Activate.ps1

Install the library inside the activated environment:

pip install aspose-3d-foss

Record dependencies for reproducibility:

pip freeze > requirements.txt

To recreate the environment on another machine:

python -m venv .venv
source .venv/bin/activate   # or the Windows equivalent
pip install -r requirements.txt

3. Verify the Installation

After installing, verify that the library imports correctly:

from aspose.threed import Scene

scene = Scene()
print("Aspose.3D FOSS installed successfully")
print(f"Root node name: {scene.root_node.name}")

Expected output:

Aspose.3D FOSS installed successfully
Root node name: RootNode

You can also check the installed version with pip:

pip show aspose-3d-foss

This will print the version, author, and license (MIT).

Quick Start: Load a Scene and Inspect It

The following script loads a 3D file, prints information about every mesh node, and re-exports the scene to GLB format:

from aspose.threed import Scene
from aspose.threed.formats import ObjLoadOptions

##Load an OBJ file with material support
options = ObjLoadOptions()
options.enable_materials = True
options.flip_coordinate_system = False

scene = Scene()
scene.open("model.obj", options)

##Print the scene hierarchy
print(f"Top-level nodes: {len(scene.root_node.child_nodes)}")

for node in scene.root_node.child_nodes:
    if node.entity is None:
        continue
    mesh = node.entity
    print(f"  Node: {node.name}")
    print(f"    Vertices: {len(mesh.control_points)}")
    print(f"    Polygons: {len(mesh.polygons)}")
    if node.material:
        print(f"    Material: {type(node.material).__name__}")

##Re-export to GLB (binary glTF)
scene.save("output.glb")
print("Saved output.glb")

If you do not yet have an OBJ file, the library can also create a scene from scratch:

from aspose.threed import Scene

##Create an empty scene and save it as glTF
scene = Scene()
scene.save("empty.gltf")
print("Created empty.gltf")

Platform Notes

Windows, macOS, Linux: The library is identical on all platforms. There are no platform-specific code paths or binary extensions.

Docker / serverless: Because there are no system-package dependencies, the library works inside slim Docker images (such as python:3.12-slim) without installing any additional apt or yum packages.

CI/CD: Add pip install aspose-3d-foss to your CI pipeline’s dependency step. No additional setup is required.

Conda: If your project uses Conda, install the library from PyPI inside a Conda environment:

conda create -n my-env python=3.12
conda activate my-env
pip install aspose-3d-foss
