TRAINING RESOURCES
Software
1. MATLAB: https://www.mathworks.com/campaigns/products/trials.html
- Trial version is good for 30 days. Requires you to create an account
- PIVlab requires the Image Processing toolbox so select the Image Processing and Computer Vision package for download
2. PIVlab: https://www.mathworks.com/matlabcentral/fileexchange/27659-pivlab-partic...
- Download the zip file (not the toolbox) and unzip
- Install the app (PIVlab.mlappinstall file) in MATLAB (APPS -> Install App)
3. CloudCompare: https://www.danielgm.net/cc/
- Download and install the newest version available for your computer under the download tab.
