sketch to CG

[kicks]

 

Thanks for any ideas.

I'd be very wary of doing this without plans.

 

But.........most 3d apps allow you to put a background image in the modelling viewports and this is the only way I can think of to get a good match.

I once had somebody show me something like this done, but i never had the chance to ask how they did it. I don't know how long it took but it was neatly made.

This is what I was thinking of.......

If you have no plans and dimensions, it's all going to be guesswork but getting the proportions right is half the battle.

perhaps it's easier to do it the other way around.

Make a cg that's close enough to the sketch and then let them sketch over the CG image, because you never know how accurate the perspective is in a sketch, but with cg it's perfect.

 

but maybe im missing a point here.

I have done this before, never for a client all just myself studying, but you just have to become a good estimator to get this done. Estimate the size of one object which you are pretty sure of the size of like a window or the a tree or something, then use that size as reference estimating distance from view and stuff... Good luck!

If it is just a sketch done freehand (without first setting up the perspective), then it will never match. However, if it's a sketch created from a properly set up perspective, then you can recreate the same viewpoint position.

From a long history of hand perspective, I 100% agree.

 

However--look at the SketchUp site. They have some tutorilal videos, one or two show how to make a model out of a photo (your sketch instead). Its camera mapping, do-able in other apps, easily in SU.

that's what i was thinking of. that bird house demonstration they have. not totally accurate, but i think you can get good results out of the approach. i usually just eye-ball it with the masses, then compare in ps, and make the adjustments. then add the detailed stuff.
