[osg-users] Render normal vectors to image

[Han Hu]

Hi,

Thanks!

I can use osgUtil to compute the normal vectors on the fly. My question is how to render the per-vertex or per-triangles to the image, e.g. the color is the (x,y,z) of the normal vector, rather than the color of texture.

Cheers,
Han
