sim-asset-tools 0.4.0

Portable tools for preparing simulation-ready mesh and model assets

sim-asset-tools

sim-asset-tools prepares portable assets for robotics and physics simulation. Its sim-assets CLI provides standalone mesh processing, object-bundle generation, and reusable primitives for higher-level asset workflows.

Installation

Add the CLI and library to a project:

uv add sim-asset-tools

Project wheels support CPython 3.10–3.13 on Linux x86_64 or ARM64, Windows x86_64, and macOS 12 or newer on Apple Silicon.

Supported workflows

Command family	Support
mesh	Normalize, OpenVDB SDF, ACVD remeshing, CoACD decomposition
prepare object / prepare objects	GLB, OBJ, PLY, STL to MJCF and/or URDF bundles
check object	Object-bundle integrity

See the runnable examples for CLI commands and uv run sim-assets --help for all available options.
