Re: shadow for model The software used by EADS for the presentation at Paris air show 2011 don't use shadow effect, it use a mirror effect.
To do that, you just have to render your scene in 2 pass with different point of view. (It's not a GLC_lib built in function). @+ |

Just change the current OpenGL view matrix before the call of GLC_World::render(...); Something like that : Code: glScaled(NewPlaneNormal.x, NewPlaneNormal.y, NewPlaneNormal.z); glTranslated(PointOnTheMirrorPlane.x, PointOnTheMirrorPlane.y, PointOnTheMirrorPlane.z); To create shadow effect, you can disable lightning before rendering the mirror. Tips : mirror must be render before normal scene... Recommended reading : More OpenGL Game Programming. It's not a GLC_lib built-in function... It's a pure OpenGL. @+ |
