Tiny Texture Tumbler

A small JS library to create textures. Mainly useful for file size restricted competitions. Used with much success in Q1k3.

Example

Editor

Usage

Include the ttt.min.js into your project.

The ttt() function takes an array of texture definitions and returns an array of canvas elements. You can use the canvas element as the source for ctx.drawImage(), to create WebGL textures with gl.texImage2D() or to just add them to your HTML.

// Example texture 32x32 pixels with a pink background
ttt([[32, 32, 0xf0ff]]).map(canvas => document.body.appendChild(canvas));

Notes

  • Colors are saved as 16bit values. Each nibble (that is each 4 bit value or each character in hex) correspondes to an r,g,b,a value.
  • The library currently has very few different drawing operations. Don't be afraid to extend those to whatever else you need. But keep in mind that you can draw circles and many shapes with the text function and a single letter or emoji :^)
  • The rectangle function actually draws 3 rectangles with different colors at 1px offsets. This is useful to create insets or bumps. You can set the alpha of the top/bottom to 0 if you don't need it.
  • You can draw a texture onto itself. If you modify the x/y position and the alpha value, you can get some cool effects.
