Hello. As prompted by your hasty and wrong edits (which you surely noticed), may I suggest you think about something you don't clearly understand before editing ("correcting") a correct article (eg your edits on refraction or phong shading). This isn't meant to be harsh, but it seems you hastily assume the error is in a wiki page with a good history, instead of in your own reasoning, which leads me to think that you come to edit these entries having just enthusiastically learned (but not mastered) new stuff :-) 70.81.15.136 ( talk) 11:14, 10 February 2009 (UTC)
