OpenVCAD is volumetric multi-material modeling language and compiler developed by the Matter Assembly Computation Lab at the University of Colorado Boulder. OpenVCAD is an automatable volumetric design framework that can fully leverage multi-material fabrication. OpenVCAD provides a scriptable suite of constructive solid geometry and functional design methods that enable the representation of complex objects with hundreds of materials. OpenVCAD allows for full spatial control over the material composition of an object. Additionally, it provides functional grading and convolutional blending techniques to generate parts with dynamic mechanical characteristics. This research tool is intended to be used for the design and development of new meta-materials, digital allows, and compliant mechanisms.

Installing OpenVCAD

OpenVCAD can be either installed from precompiled binaries for your system, or built from source.

Pre-compiled OpenVCAD binaries

Pre-compiled binaries of the OpenVCAD compiler can be found in releases. These include two versions:

1. IDE-like program with UI and OpenGL-based rendering preview
2. Standalone command-line application that compiles .VCAD scripts into PNG stacks, OpenVDB grids, or binary voxel files.

Building from Source

See building instructions for more information.
