it s good for architacture to trender some sections so i wish that there is section cut rendering with M~W cam . so we can render 2d or 3d building in section .

to rendering like that with out cut in the model in half

yeah... that would be REALLY cool. Just have a 'non-render' volumetric surface.. sort of a boolean-subtract rendering object, so you could just create a shape to outline where is NOT visible, then render away...

you could cross-section a complete model of an engine, house, etc. in minutes! I'd hate to imagine how long it would take to make 10 cross-sections without such a tool!

I agree as far as this should be part of the 3d program you use and not a part of the renderer, it makes no sense to waste code on this feature when it can be done faster and easier with current 3d programs and/or plugins for those.

the key here, and what I was trying to get across is the NON RENDER surface... this would allow any application to remove areas for render, kind of a boolean hiding technique. The important thing here is...

non destructive! We don't want be forced to actually SLICE up the model which creates two primary issues, both the lack of flexibility - once sliced... well... it's just plain done - and time. Moving a big cube around in (for example) lightwave then hitting the render button makes a lot more sense to be then slicing the model, saving, fixing errors created in the cut, etc. etc.

it needs to be supported by the renderer and non-destructive to the original geometry.

it would require volumetric surfaces... or not... worst case scenario would be a 'transparent' texture. it would be easier to 'texture' for cross section then to remove geometry.

but a volumetric surface that would make all surfaces transparent would have a lot of value. Bryce does it... can't maxwell? Bryce does it's boolean operations via RENDER, take a few objects, group them together, make one negative, or use two objects to render only the common spaces between the two. Works really well for such things as the Terminator time bubble effect, since you could apply a texture to this 'negative' object and it would take a bite out of another object and leave it's texture in the space carved out.

mmmm... bite of cg object... tasty
