[osg-users] osgShadow question

Hi Wyatt,

Depends on whether your object has a texture or not. Although now, since 
texture lookups are so cheap these days, I would suggest you save 
yourself some aggravation and just apply a white 1x1 texture to the top 
of your scene graph (which will thus apply to all untextured objects but 
won't change anything in their appearance) and use only one shader, the 
withBaseTexture one.

See the code for osgShadow::ShadowMap for an example of such a texture 
set up.

What do HUDs have to do with this?

Hope this helps,
