In 1974 Catmull developed a new algorithm for rendering images of bivariate surface patches. This paper describes extensions of this algorithm in the areas of texture simulation and lighting models. The parametrization of a patch defines a coordinate system which is used as a key for mapping patterns onto the surface. The intensity of the pattern at each picture element is computed as a weighted average of regions of the pattern definition function. The shape and size of this weighting function… 
Texture mapping and distortion in digital graphics
TLDR
A method for mapping complex polygonal geometries is presented and enhancements to the basic unfolding algorithm either control the location of map distorition introduced at areas of severe curvature or average distortions over a larger area.
Texture Mapping and Resampling for Computer Graphics
TLDR
This thesis is the adaptation and implementation of two recently published high-quality, space-variant, constant-time ltering techniques into the author's NuGraf-3d scanline rendering system, providing a thorough overview of all phases of the texture mapping process.
Rendering Of Texture On 3D Surfaces
This paper presents a novel and computationally efficient model based algorithm for artificially rendering textures on a 3D surfaces. We use a Gaussian Markov Random Field (GMRF) for modelling the
Real-time manipulation of texture-mapped surfaces
TLDR
A system for real-time texture mapping was constructed which enables interactive manipulation of texture-mapped free-form surfaces and various application software has been developed taking advantage of this ability.
Interactive texture mapping
TLDR
An interactive texture tool is constructed, which is fast and easy to use, to manipulate atlases in texture space, and the tool’s large set of interactive operations on mapping functions are presented.
A visibility algorithm for hybrid geometry- and image-based modeling and rendering
TLDR
An object-space algorithm for computing a visibility map for a set of polygons for a given camera viewpoint and supports efficient determination of silhouette edges, which allows an image-based modeling and rendering system to avoid mapping pixels along edges whose colors are the result of averaging over several disjoint surfaces.
