Texture, Colour, and Tilings

Tiling textures
An introduction to texture tiling using characteristics of the texture itself. A general method is presented that converts any texture into one that tiles without seams. Illustrates the most common texture mapping methods in use by rendering applications. The mathematics of how to map a rectangular texture onto a sphere, creating a textured mesh in OpenGL and how to correct for polar distortion of texture maps on spheres.

Random space filling tiling of the plane
Space filling tiling of a plane (and a line or 3D) with an arbitrary shape.

Tiling on the plane
Includes Truchet tiling in 2D and 3D, Regular pentagonal tiles, block tessellation, weaving, and more. Non periodic (aperiodic) tiling of the plane: Methods of tiling that are never periodic, for example, Penrose tiles, Danzer tiles, Chair tiles, Trilobite tiles, Pinwheel tiles. Most of the tiles are presented accurately and large enough to be printed and cutout.

No amount of genius can overcome a preoccupation with detail. Law 8, Marion Levy Jr.

Texture Library

These textures may be freely used as backgrounds, textures in 3D scenes, parts of images, etc but they may not be redistributed as (or part of) a texture collection. The textures are divided into the following categories and an attempt has been made not to burden any single page with too many images. Be aware that some textures can be interpreted in a number of ways. If you find any of these textures useful then why not improve the collection by contributing some of your own. In order to submit your textures to this collection, email myself for further details or simply attach the texture images in an email.

Note: Not all of these textures tile (at least not automatically). By clicking on any texture you will be given a page with the texture as a tiled background image where you can visually inspect the result of a straightforward tiling. Mirror tiling will need to be arranged by yourselves, ie: WWW browsers don't yet support it.

Perlin noise and turbulence
Creating arbitrary dimensional textures and other natural effects using techniques credited to Ken Perlin.

I wanted to persuade myself that these flaws were only apparent flaws, that they were all part of a much vaster regular structure in which every symmetry we thought we observed really corresponded to a network or symmetries so complicated we couldn't comprehend them all. Italo Calvino

Edge blending
Edge blending two (or more) images using commodity projectors. Blending across left/right edge of a 360 degree panoramic image.

Image histogram matching
Modifying one imag so its historgram matches that of another, includes histogram normalisation (also known as equalisation).

All that glitters has a high refractive index. Anon

Description of various colour spaces
Including the RGB colour values for "familiar" named colours, the X-Windows named colours, the Resene RGB Values List, and traditional WEB browser palette. Resene RGB Values List formatted for POVRay. Converting between various colour spaces. YCC colour space and image compression. Colour ramps: Mapping some scalar value onto RGB colour space with applications in data visualisation, a simple storage format, a HSV colour ramp/selector, and index colour tables. Brief description of gamma correction. Colour space images (Note: these are not corrected for display gamma) Hue/intensity colour circle, Grey diagonal ramp, Colour mixtures, Wavelengths, Colour bands: Red = 700nm, Green = 546.1nm, Blue = 435.8nm

Various simple image processing techniques
Including Bicubic image interpolation: The standard method for scaling an image up or down.
