• PabloL 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. It does not fail, but neither does it draw anything. Could you please tell me what I'm doing wrong, or maybe weather there's some easier way to do that Thanks Libor ...Show All

• Robert te Kaat - IS What the heck has happened to utility.timer and directxtimer?

  I've been working through an introductory Managed DirectX book and there is some code that refers to a thing called "utility.timer" and a call to "DirectXTimer.GetElapsedTime". Neither of these things compile for me in VS.NET 2003 with DirectX 9. I can't seem to find anything at all on the utility function, and damn little on DirectXTimer. Obviously these things have become defunct, but what has taken their place Where should I be looking ...Show All

• PaoloTCS Specular reflections aren't working right

  I'm having a problem with specular reflection.  It flickers as I move around my object. Sometimes when I'm looking at a face, and I swivel the camera just a few degrees, I get specular reflection.  When I swivel a few more, the reflection is gone - leading to the flicker. But specular reflection is only based on the position of the camera, not the direction it's lookin ...Show All

• Mans 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
