View Full Version : How to model large scale projects
16th Dec 2002, 01:44 am
Hi guys, just pondering the following,
i am fairly involved in 3d modeling and rendering when it comes to exhibition displays and furniture,etc. what i would like to know is
what meathods are used when it comes to photomontages of architectural buildings. i know the basics when it comes to photomontages, but what modeling meathods are used when it comes to 3d presentation of buildings and large scale projects.
obviously you dont model the whole building with all internal floors and walls, it would just take too much time. and do you model the fiirst floor and copy that floor up a few times to get your levels?

Well, quite obviously it's only worth modelling what you are going to see. So there's no point building an interior if all your views are external. As far as the rest goes. If your building is modular, just build one module and copy it then add any other detail. You should always aim to be as efficient as possible.

However, when doing exterior work, sometimes you're able to see through glass, so it can be advised to put something inside, maybe just some dummy-walls...

tell me if im wrong, but i would think the process below
would be used.
would you draft the walls in 2d, and extrude them into 3d,
assign your layers,e.g glass,aluminum,concrete,etc
then bmake the wall section,and array the block (if its a high rise).
assign materials to layers
render to file
import into photoshop and overlay over digital image.
i was wondering if there were any shortcuts that you usually discover by mistake around the 3rd or 4th job, that makes life easier.
thanks for your feedback by the way

That looks about right to me - in general.
Of course there are always the curved balls that every project thows at you but you seem to have the basic outline sorted out. Let us know how you get on.

There are some cool building/room renders at www.cgarchitect.com particularly the bathroom one, with blinds showing a good use of shadows.
I would have some interior renders as well as exteriors, this way the model has more depth and scope. Viewports are ideal for this.
I would import the background into autocad rather than into Pshop.
If you want to tweak the viewing camera, perspective etc then you would have to re-import it into pshop.
