      • Is there a way using the sprite batch object that you can render several rectangles, but when alpha blended, it looks like the entire object was rendered first as a single opaque image, and then that image was alpha blended, such that you would never have known it was several smaller pieces assembling the final object Instead of normally seeing each rectangle blended as it overlays another rectan

      • Hi, at the moment i am wondering how to deal correctly with a terrain in XNA. For now i just have a static terrain model loaded from file. So i have an object (a buggy for example) and want to get some physics on it, therefore i need to check for collision with the underlying terrain. The collision with the buggy could be done with a boundingbox, but the terrain needs to be checked per face (3

      • Hi; I'm currently doing my programming on a 37 inch Sharp Aquos TV. My game is loading a moderately large mesh (64x64 triangles) and displaying it on screen in wire-frame mode. The strange thing is, when I rotate the mesh .....the mesh dims! At a rough guess, it's only 50% of the brightness it's displayed at when not being rotated. Because I run my apps at full speed for performance testing (abo
