Practical overview
When it fits
Use it when you want a code-level MeshGPT implementation and can supply mesh data and undertake model training before generating assets.
Who it is for
- Developers and researchers prototyping 3D mesh-generation models in PyTorch.
- Teams exploring a mesh-generation component for a 3D content workflow.
- Practitioners comparing attention-based approaches to mesh generation.
Documented uses
- Train an autoencoder on vertex and face data.
- Train a transformer to model mesh sequences and generate new asset geometry.
- Condition transformer training and generation on text descriptions.
- Tokenize mesh data for use in a multimodal transformer.
Requirements & limits
The public GitHub repository identifies the project as MIT-licensed and documents installation with pip.
- The documented workflow requires training the autoencoder and transformer before generation.
- Variable-length face data should be padded with -1.
- Generated face coordinates and masks need post-processing into an asset.
- Text conditioning is available through the transformer’s documented
condition_on_textandtextsarguments.
Check current requirements in the official documentation. Source-based guidance does not mean OpenViST has run or independently tested this project.
Install the package and begin a mesh-model workflow
Install the library and identify the documented classes and data inputs for training a mesh autoencoder and transformer.
Before you start
- Python environment with pip
- PyTorch
- Vertex and face data; variable-length face data should be padded with -1
Steps
Install the package with the command below.
pip install meshgpt-pytorchImport
MeshAutoencoderandMeshTransformerfrommeshgpt_pytorch.Create an autoencoder and pass vertex and face tensors to it.
Create a transformer using the autoencoder and pass mesh data to its forward call.
Expected outcome
The package is installed and the documented model workflow is set up to calculate training losses; generation follows after training.
Guide limitations
- The README says generation follows substantial training of both stages.
- Generated geometry requires post-processing.
- The installation example does not specify a full environment or hardware requirements.
