Thanks!<p>to answer a few of the suggestions:<p>* There is in fact nothing really new about it. I know it exists and It was mainly me being interested in that topic. And I don&#x27;t know, if I am ready to actually invent or think of something really new :)<p>* Right now, there is no time left to look to DirectX. I might go for it later but for the moment I feel more like doing stuff that looks cool&#x2F;good or has interesting mathematical background than going for other system&#x2F;DirectX.<p>* Yes, good point. I will have a look at lighting the next weeks!<p>* OK, removing typos is probably the first step ;) I&#x27;m on it!<p>* Also good point. Will do that!<p>* The reflection is technically correct, but I kinda cheat a little by lowering the reflection-vector to get a little more reflection out of the scene. It hides a bit, by reflecting also part of the scene which is normally cut off.<p>Thanks for the suggestions and critic :)
