3D Wire Frame/Grid Help
Hi,
I am looking for a tutorial or some helpful hints to taking a shot of a car or person and then I want to animate the real photo into a wire frame/grid overlay version . Like the car/person grid is scanning object to get it’s information.
The MTV show Room Raiders uses an effect that is very close to the same thing I wanna do. Please let me know if someone can help me out with this.
Thanks

First, you need a wireframe image and a normally rendered image of a 3D object, created in a real 3D application. You might just need the 3D wireframe object, if you freeze your footage and use it as a guide for creating the wireframe object. This is not a quick, automatic process, and it requires a real 3D app.
There’s no way to use software to create a wireframe from a movie or photograph, unless the movie is a shot of the object rotating on a turntable, and the software is reeeeally expensive. And the object already has wireframe lines marked on it. 🙂
Once you have the wireframe image layer that matches the other image layer, you can animate the shape of a mask applied to the wireframe layer so it gradually reveals the wireframe layer and hides the other one.
Basically, the transition from one image to the other is very easy … but getting the wireframe images of the object is the 3D challenge.
Anybody else?

Essentially what you are asking about is something called Photogrammetry – do a google and you’ll find lots of links.
Software avaialble for our type of work can be found here ImageModeller from Realviz.
