Hallo!
ich beschäftige mich nun seit 3 Tagen mit Direct3D und haben ein Problem mit der Position der D3D Lichtquellen. Die Lichtquelle (hier Nr.1 *) beleuchtet nicht den Bereich um Ihre Position in der Welt, sondern scheint sich irgendwie mit der Camera zu bewegen.
Kann mir jemand sagen, ob ich hier irgendetwas falsch mache? (Den relevanten Quellcodebereich habe ich unten angehängt und ein wenig mit Kommentaren versehen)
Danke!
