• VeePee Sprite Problem

  I'm trying to do some simple 2D graphics with DirectX 9.0 (April version), so the first step is to display bitmaps. I found a tutorial that applies a texture to a rectangular triangle fan (quad), and that works perfectly. However, when I try to display a bitmap with the ID3DXSprite object, it looks a little blurry, as if the bitmap is offset from the screen coordinates by some fraction. When using the texture-quad method, apparently you must ...Show All

• Eric Feunteun Multiple windows by one device

  Hi! I'm looking for some easy way to render into multiple widows by only one device. I'm using managed directX in C#, there's an overload of the Present method that takes a control and claims that it will draw onto the control, but I can't make it work.

• cycledesign The never ending pain that is my 2D tile texture problem.

  I want to make a nice 2D tile game - I can plot 2D tiles fine as 3D textured quads, pixel perfect. But when I move the camera by translating the view matrix - the pixel on the border of the tiles sometimes dissapears and sometimes it thickens to two pixels worth. This is the original plot. Then when I move the camera down a bit, the last line of pixels on the textures is gone :( Here's the very concise source illustrating the problem (C# Vs ...Show All
