• clark121121 Pick-Through Multiple Selection

  Hi! I'm developing a 3D scene arrangement tool in C# and I want to implement a feature for users where you can select objects behind other objects. I've searched the web for examples on how to get all of the meshes gathered from a pick ray (instead of only the nearest) but I haven't found any references on how to get or store that information. Are there any resources for this that I might have missed If not, may I get some advice or (bless ...Show All

• DanaDBA Problem with setting Mouse Position with SendInput()

  Hi, I have an OpenGL Application and want to use the mouse for a Free-Flight Camera. The mouse should not be restricted to the Monitor boundaries... I get the mouse-position with WM_MOUSEMOVE and stuff. Because of the requirement of no boundaries i have to use a different system of saving my Mouse Position. I want to save an absolute position of the mouse x and y. To calculate the x and y I want to get a relative mouse movement each frame. ...Show All

• John Rice 3d Mesh background with sprites on top

  Ok, so i'm a complete noob to Directx. But the basic idea is to create a background ( I am assuming at this point a mesh with texture mapping) that is zoomable and scrollable (no need to rotate, although that may be added in the future) with simple 2d objects on top of the background ( right now I was planning on using sprites) I am using directX 9 and programmingin c#. Right now the problem is the sprites and the map are bei ...Show All

• RosarioCappello Create Displacement from Normal Map

  This is a general graphics question. I was wondering if anyone knew a way to create a displacement map from a normal map. Any and all help would be appreciated. Thanks, Charlie In general, that can't be done, because the specific displacement is not part of the normal (the normal is normalized). You can do a crappy job by starting in one corner, and walking scanline by scanline, adding or subtracting a delta based on what the normal is d ...Show All
