Projection Mapping

Recommended Posts

Guest Sao_Bento

Are you referring to the graffiti / street art trend? Around here, most people will think you mean the process of projecting an image onto geometry inside a 3D application. I've done plenty of projecting onto real world things as a basis for painting - can't say there are many tricks other than making sure you can control the ambient lighting. Obviously the color of what you're projecting and the surface you're projecting onto play into it as well. Plan for contrast.

yea i meant real world projection. I have seen videos of projections on sculptures, shoes, and even people. I was just wondering if there were any specific techniques to map my "canvas object" in a 3D program. So far im stuck with guessing and checking, which is really hard to do when i want crisp, accurate edges.

Ironically, doing it in the computer might be the best way to plan - measure out the environment you're working with and re-create it in a 3D app or After Effects, then you can test more easily. Profiling the projector seems like a good idea as well - get to know it's limitations, max distance, etc.

Most of what I have done is just projecting artwork created in Illustrator onto an object, then using as a tracing pattern for paint. I remember an interesting discussion with some guys who were doing projected set elements for dance companies, but I don't remember the specifics at the moment.

Check out some mapping software and their tutorials >> http://madmapper.com / http://meshwarpserver.org ( free ) http://hcgilje.wordpress.com/vpt/ ( free ) or do some searches for projection mapping tutorial..

Good luck!

I have done a handful of projection mapping for live events and onto complex 3d objects. I would give different tips based upon how complex the object is that you want to project on, how powerful your projectors are, if you are projecting inside a studio environment or outside and what your point of view is when projecting. But initially we always bring the object into a 3d program and lock the camera to align the projectors to. If it's a building structure for example, we will take a super high resolution digital scan of the surface. If it's a product such as a car we will usually be provided with the 3d model to align the deigns to.

@dbrodi -- ok i see, i have been making progress with 3d programs and recreating what ever object it is i wanna project onto.

 

@jean poole -- wooooow that helps tons!! soo much good info!

 

thanks to all!
