Texture and Colour

Tiling textures on the plane 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.

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

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.

Various periodic tilings Includes Truchet tiling in 2D and 3D, Regular pentagonal tiles, block tessellation, weaving, and more..... Hexagonal tiling and SHM Calculator Including MacOS-X and Linux software for experimenting with transformation in the Spiral Harmonic Mosaic.

Texture Library [These textures are available on DVD]

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.

Texture mapping 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.

I don't do drugs. If I want a rush then I getout of the chair when I'm not expecting it.

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

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.

Colour space images (Note: these are not corrected for display gamma) Hue/intensity colour circle, Grey diagonal ramp, Colour mixtures, Wavelengths, Colour bands.

YCC colour space and image compression A simple compression scheme for 24 bit colour images that takes advantage of our preference for intensity differences rather than colour.

All that glitters has a high refractive index.

Do not try to teach a pig to sing hymns. It wastes your time and annoys the pig.

I have a stepladder. It's a very nice stepladder, but it's sad that I never knew my real ladder.
