Hello Lego Fans, Today I want to present something for all football-fans among lugnet. I hope everyone enjoys the World Cup in South Africa so far. We Germans definately do :) By using Ldraw I build severel known players of the teams particapating (...) (14 years ago, 16-Jun-10, to lugnet.announce.moc, lugnet.cad, FTX)

(...) <snip> (...) Wow, this is amazing. I had no idea you could do these kinds of things with shaders. Like Don I too think it's time for me to get a good book/document on using shaders in OpenGL. Thanks for the revelation. Roland (14 years ago, 16-Jun-10, to lugnet.cad.dev)

(...) Hoo...that takes me back! :-) Doing the second shader was a bit of a blast from the past, actually - it's over 10 years since I last wrote assembler in anger! Alex (14 years ago, 16-Jun-10, to lugnet.cad.dev)

(...) ... Wow, that is simple. It looks just like the description of the algorithm in the LDRAW specs. I haven't felt this old since manipulating the colormap for animation went outta style. :^) Thanks for sharing, Don (14 years ago, 16-Jun-10, to lugnet.cad.dev)
