Hi all,

I have a scene with about 30.000 hexagonal-Z prisms which in their turn
generate one large hexagonal-Z prism (i.e. a hexagonal-Z lattice from a
numerical calculation). Each small prism has its own color based on the
results from the calculation. If I just render this scene with the large
prism a union{ prism ... prism... prism ..} of the small prisms, it takes
about 10 seconds in total (parsing+rendering). However, when I use a
clipped_by {plane {-z,0}} to cut the large prism in half to see the inside,
rendering time becomes 10 hours. Is there a faster way (clipping each small
prism seperately, specifying the bounding box by hand,...) to do this?


thanks,

gert
