Seamless Texture Atlas system pipeline.

Abstract:

Texture atlas parameterization provides an effective way to map a variety of color and data attributes from 2D texture domains onto polygonal surface meshes. However, the individual charts of such atlases are typically plagued by noticeable seams. We describe a new type of atlas which is seamless by construction. Our seamless atlas comprises all quadrilateral charts, and permits seamless texturing, as well as per-fragment down-sampling. We demonstrate the use of this atlas for capturing appearance attributes and producing seamless rendering.

Some figures from the paper:

	Rendering normal-mapped Igea model. (a) Seams introduced because of interpolation across adjacently-packed chart boundaries. (b) Our correct boundary filtering and lookup eliminates these seams.
	Texture-mapped Bunny model and its flat seamless atlas. (a) A close-up on a part of Bunny with a patch boundary (with the patches shown next to it). (b) Seamless texture-mapped Bunny. (c) The flat atlas.
	Normal-mapped Teeth model with varying level of detail. (a) Seamless rendering with LOD. (b) Rendering the corresponding mesh without normal map.
	One-million-triangle Cuneiform tablet model, rendering at several of its individual mip-map levels to illustrate the seamless filtering.
