- <p>Lucy model from <a href="http://graphics.stanford.edu/data/3Dscanrep/">Stanford 3d scanning repository</a>

- (decimated with <a href="http://meshlab.sourceforge.net/">Meshlab</a>).
|
|
|
-
|
|
|
- <p>Please be patient while the mesh is loading. It may take a while, it's 2 MB file.
|
|
|
-
|
|
|
- <br/>
|
|
|
- <p>Best viewed in Chrome or Firefox using WebGL renderer.
|
|
|
- <p>Canvas renderer is very slow for this demo and only diffuse material works there.
|
|
|
- <p>Use the flag --allow-file-access-from-files if working localy in Chrome.
