More Fun With Texture Projection

22 Mar 2010

Updated with video (8/25/2010)

Here I'm just expanding upon the 'texture extraction' idea posted before. This version maps video onto 3D objects in a much more direct manner by using ray-casting, like the examples in the last several posts.

Controls:

• Mouse rotates object
• Mouse drag moves object
• [SPACE] remaps the texturing of the 3d object
• [ENTER] cycles through different 3D primitives
• [H] shows full list of kludgey hotkey controls

Although this piece dispenses with the encumbrances of an AR marker or any application-like functionality, I think the method being used here has some potentially interesting uses for an augmented reality-based design application. (Or for more whimsical uses like "upload-your-face" done in 3D). I've disabled backface detection, so the imagery gets mapped on all sides of the object rather than just the camera-facing polys, which makes it more visually interesting. Live demo above requires webcam.
