This lapped texture model renders at 25 frames per second at a
resolution of 1024x1024 pixels using ordinary texture mapping
hardware on a PC. It is created by covering a 15,000-triangle
mesh using 282 overlapping copies of the inset texture patch.
The user spent 15 minutes specifying the desired texture
direction over the surface. Then, automatic placement of the
texture patches took 2 minutes of computation. Due to the
overlapping texture patches, each face of the original mesh is
rendered 1.6 times on average. Lapped textures allow large,
arbitrary surfaces to be covered with a compact texture
footprint. Emil Praun, Adam Finkelstein, and Hugues Hoppe.
