Hey Guys, I've run into some problems regarding the textures in a Direct3D-Application. For the sake of simplicity I'm using a surface which contains 4 vertices and 6 indices. The surface is built with 2 triangles. The exact coordinates of the two triangles can be found here: http://gyazo.com/2b9...8179f3a8e95063d / http://gyazo.com/9b6...a5791bd547c93ce I can't make out any mistakes concerning the position-coordinates and UV-coordinates (at a first glance). This is the Texture I'm using: http://gyazo.com/12d...2f7cada915f3b3e Let's get to my Question: Why is the pixel-shader mapping the texture like this? http://gyazo.com/1de...4aeb5c0713c2729 I'm suspecting the UV-Coordinates because they are most likely causing my problem. What do you think? I would be very happy to read a few suggestions regarding my problem solution.
