It will.

Allegro already supports gouraud shaded polys (linear interpolation of color between the vertices), with the POLYTYPE_GCOL and POLYTYPE_GRGB drawing modes. If you are talking about phong shading (interpolation of the surface normal, and doing lighting calculations for each pixel), I'm not planning to add that myself but anyone who fancies it is of course very welcome to give it a go... -- Shawn Hargreaves - shawn AT talula DOT demon DOT co DOT uk - http://www.talula.demon.co.uk/ Beauty is a French phonetic corruption of a short cloth neck ornament.
