His Words? I'm fine with you copying <a href="http://www.realtimerendering.com/blog/gpu-pro3-is-available-for-order/" rel="nofollow">my blog post</a>, but it would have been nice to say "this is a repost of Eric's entry on the absolutely-wonderful, stunningly brilliant, and life-changing <a href="http://www.realtimerendering.com/blog/" rel="nofollow">Real-Time Rendering blog</a>". In academic circles this is called "plagiarism". I'll give you some slack since you did the great task of editing one of the sections of GPU Pro^3 (thanks!). I would appreciate it if you updated your entry and gave credit where it's due - my words aren't deathless prose for the centuries, but they deserve credit. Feel free to remove this comment once you have. “My Life, My Projects…” His Words?

]]> Comment on First Project: Texture Compression and DXTC Transcoding by Sebby http://www.sebbylive.com/2011/07/17/project-texture-compression-dxtc-transcoding/#comment-27 Sebby Tue, 06 Dec 2011 17:19:42 +0000 http://www.sebbylive.com/?p=74#comment-27 I just glanced over the article. Looks like a similar approach to what I take. The idea of my compression is to take the min/max color channels and use color prediction in order to apply a lossless compression to the values. The selector bits are a little more tricky as they are more random in nature. The best I could find is a simple huffman algorithm which does provide some gains depending on the composition of the source image. I just glanced over the article.

I'm not sure how expensive it is to ensure these endpoints are encoded accurately though.
