Process and Generate 3D Assets for Scenario Simulation
R2026bThe 3D Asset Processing Library for MATLAB® support package enables you to create, import, transform, and export 3D assets for use in driving scenario simulations and other 3D applications. The support package provides an end-to-end workflow for working with 3D geometry, AI-based asset generation, mesh manipulation, and file I/O across industry-standard formats.
Create and Import
Generate 3D meshes from images or text prompts using AI-powered deep learning models to produce textured 3D assets.
Read 3D mesh and scene data from one of these common file formats: STL, OBJ, PLY, OFF, DAE, 3MF, FBX, USD, USDA, USDC, USDZ, glTF, and GLB.
Visualize and Segment
Visualize assets in an interactive 3D viewer or convert them to patches of colored polygons for custom rendering.
Segment meshes into subparts based on shape thickness, visualize, and label the segmentation results.
Edit and Transform
Represent 3D geometry with editable vertices, faces, UV coordinates, colors, and PBR material properties.
Build hierarchical scenes by adding meshes as named nodes with parent-child relationships and per-node transforms.
Apply spatial transformations to meshes and scenes, including rotation, translation, scaling, resizing, and arbitrary homogeneous transforms.
Interactively create and edit 3D assets using the Asset Generator app.
Export
Write 3D mesh and scene data to one of these common file formats: STL, OBJ, PLY, OFF, DAE, 3MF, FBX, USD, USDA, USDC, USDZ, glTF, GLB, and URDF.
To process and generate 3D assets, you must download the 3D Asset Processing Library for MATLAB support package from the Add-On Explorer. For more information on downloading add-ons, see Get and Manage Add-Ons.
