webgl-texture-utils

Utilities for working with WebGL textures with an emphasis on loading compressed formats.

dds.js

Currently the only file in the library, contains functions for processing DDS texture files.

Simplest usage is as follows:

var s3tcExt = gl.getExtension("WEBKIT_WEBGL_compressed_texture_s3tc"); // Substitute MOZ_, etc depending on browser
var ddsTexture = loadDDSTexture(gl, s3tcExt, "lena.dds", function(texture) {
    // Called when texture is finished loading
});

loadDDSTexture returns a new WebGL texture and populates it with the DDS image data when it has loaded. For more advanced loading see uploadDDSLevels in the source file.

Thank you to Rich Geldreich for developing the Crunch texture compression library and Evan Parker for porting it to Javscript via Emscripten
