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

|
|
|
+
|
|
|
+ <p>Please be patient while the mesh is loading. It may take a while, it's 4.5MB file.

|

|
|
|
+ <p>Best viewed in Chrome 8/9 or Firefox 4 using WebGL renderer.
|
|
|
+ <p>Canvas renderer is very slow for this demo and only diffuse material works there.
