• Forkbeard Performance problem with Texture.FromBitmap

  I reduced program boot time (when running from within the IDE) from 12 seconds to less than 1 second by re-writing Texture.FromBitmap using unsafe code.  For me it was easy because I'm only using 32 bit textures and 32 bit bitmaps.  It would be nice to see this function optimized in future releases of the SDK.  BTW, Texture.FromStream has the same problem. -Jeremy I'm having the same problem.

• tonda Managed Directx Deployment Problem

  I am making a game using visual studio .net 2003 with directx 9 2005 update.  I create a deployment project with visual studio that includes all directx.dll files and other detected dependancies.  I deploy the game to the computer on which it was developed and it works fine. Now I want to test the networking so I deploy it to a laptop.  The laptop is running windows xp with SP 2 (so .net framework is there obviously)  I ...Show All

• AnnaF Mouse Hit Testing when primatives used not meshes

  I did search the existing threads and have read them - those that I can understand - but they do not seem to apply - at least with my limited understanding. I have a "2D" card game started in DirectX3D using managed C#. I read Tom Miller's book as the basis and starting point. I have several "playing" cards rendered as CustomVertex.PositionedNormalTextured that I add to a VertexBuffer. I draw them with the DrawPrimative ...Show All

• Darryn Lavery Visual Studio C++ 2005 Express + Microsoft Platform SDK install

  I have installed Visual Studio C++ 2005 Express, the Microsoft Platfom SDK and the DirectX SDK. I have also used the " Using Visual C++ 2005 Express with the Microsoft Platform SDK " guide to set directories etc. Include directories for both SDKs are added. When trying to compile any of the example files from the DirectX SDK the compiler is telling me that one of the include files could not be opened (Cannot open include file: 'd3d9.h'). Is th ...Show All

• Real David Players move faster at higher framerates

  Okay, this is really bad. Clearly, a hard-coded "2" that's applied to my character's "Left" property on every frame render isn't going to cut it. Obviously, the game will run slow on crappy hardware, and there's not much I can do to prevent that. But the game shouldn't run faster on really good hardware! How can I cap the movement speed, or better yet, guarentee a certain speed within reason I can already calculate frames per second, and h ...Show All

• Grace Cheng Graphics Engine Design

  I am looking for material on designing a graphics engine. The main purpose of the engine will be tech demo development and function as  shader playground. To start with I have some ideas about decoupling materials and shaders. I would like to have the flexibility that an object can have multiple materials. One part could be a diffuse surface with phong illumination, another part of the same object could be a bump mapped rusty surface w ...Show All

• Ours Prefered Env

  I guess I'm just curious how many of you fair people use solely C++ for your DirectX babies and how many use the managed env Why do you prefer one over the other Could it be that managed env is superseding C++ in DirectX Contribute your opinion! Language/platform of choice can be a fairly "religeous" choice amongst many programmers - so you'll be lucky to get many genuinely objective answers It is worth real ...Show All

• Itzhak Transparent textures again

  Hi, I'm bringing the transparent issue once again to this forum, mainly because after of doing a lot of google searches, forum searches, etc, I still can't get transparency to work. I've created a png file that has transparency. I know it is correct, because I've opened it with the D3d texture viewer, and I can see the alpha channel. I've created a simple object and assigned the texture to it in 3ds max. I've loaded the object but the transpare ...Show All

• William Vaughn 16 channel Real Time signal rendering: Should I go for DirectX?

  I'm refurbrishing an old VB6 application that displays up to 16 signals, at 100 samples per second, along with some icons on the screen. The user decides on the on-screen resolution by means of a zoom function key. Now in the design phase, I need some more information to decide on taking Direct-X or GDI+ path. I've been going through several sample applications, and so far, I've got the feeling that Direct-X is suited to heavily drive the ...Show All

• Dave211 DirectX 10

  How will DirectX10 affect any current ATI Crossfire or NVidia SLI configurations when it's out for d/l I know that with Vista, there are drivers to update that support the new OS. If I built a system now, what can I expect what hardware not to be compatible with any API's Just to clarify, it's not DirectX10 but Direct3D10. No current graphics cards on the market today will be able to run Direct3D10. Due to th ...Show All

• James Woodall Managed wrapper causes OpenGL to crash

  I have a component that contains some 3D graphics written in unmanaged C++ using OpenGL. This component has been incorporated into a Windows form by making it into a Control and there are some crashes happening when OpenGL is called. The OpenGL call that crashes is, as far as I can tell, glTexCoord3f(), and it seems to only happen in release builds and is intermittant. When the component is run in an unmanaged test wrapper it d ...Show All
