[Aqsis-development] Rendering meshes ?

[Mikael A. <mik...@ma...>]

Hi !

Maybe some one can enlighten me on a thing, lots of objects cannot be
rendered as parametric objects, take for example if we want a box that we
twist a bit along an axis, this would mean that we must create a mesh of
polygons for it, but in the renderman spec you only supply the vertices for
each polygon, no vertex normals, so far so good, they can be calculated by
the renderer, but as we break down the polygon into micropolygons, they will
all have the same normal (for one single poygon), we might want a "smooth"
surface where we interpolate between vertex normals to get a smooth surface,
how is this done in a reyes renderer ?, it would mean that we need to pass
around the vertex normals (and interpolated ones) to the micropolygons or
something....
