[osg-users] How to draw 3D pipe?

[Trajce Nikolov NICK]

Hi Daven,

you can try
gl_FrontColor = vec4(clr,clr,clr,1.0)*vec4(1,0,0,1);

It will color it in red. The "shading" is calculated in the color -
actually it is not shaded properly, you might want to use some lighting for
more proper results. Here is a link for some inspiration:

Hope this helps

Cheers!
Nick
