CAD2Mesh

This project contains matlab script for conversion of CAD model to manifold surface mesh. Parts of the code have been taken from the following repositories:

• Learning Geometry Images
• Skeleton3D

Usage

Download

git clone https://github.com/hrdkjain/Matlab-Functions.git
git clone https://github.com/hrdkjain/CAD2Mesh.git

Environment Requirement

The project has been tested on Ubuntu 20.04 with following requirements:

• Matlab (tested on version R2021a)
• meshlabserver (tested on version 2020.09)

Project Dependencies

This project depends on Matlab-Functions.

Execution

• Copy include.m.example to include.m and modify the paths.
• The main.m script reads CAD models stored in srcDir, converts them to CAD to mesh and saves them to dstDir.
• After performing the processing, there might be few non-manifold edges left in the surface mesh, which are removed by meshlabserver.
• Often to run meshlabserver from Matlab, LD_LIBRARY_PATH environment variable needs to be set to qt library path. Use this command to find the qt tool path qtchooser -print-env | grep QTTOOLDIR.
