Hello, On the Status page should I go with this Doc url: http://www.gamedev.net/reference/articles/article869.asp That has many links and one that points to: http://iki.fi/sol/tut2.html Or just go with: http://msdn.microsoft.com/archive/default.asp?url=/archive/en-us/dnardir3d/html/d3dim.asp Anyone care to say wich of the two are better? Tom
