• Raju Sreenivasan TextureLoader gone? Alternatives?

  Hi, I'm new with DirectX and I'm starting with the December 2005 SDK.  It seems like almost every tutorial or sample I've run into uses TextureLoader to retrieve textures.  From what I've seen, and I've looked pretty hard, TextureLoader doesn't exist in Microsoft.DirectX.Direct3D anymore contrary to any documentation that I can find. Well, instead I've been using Texture.FromBitmap to load textures, which I guess is okay... But I can't ...Show All

• Jan van Casteren Thread safety and graphics device

  I am experiencing errors in the form of a locked application when I have a device (with two backbuffers) in one thread which i use for rendering while another thread attempts to lock and read the other backbuffer. I get no error. The application just freezes on the call to getBackBuffer. I attempt to lock buffer 1 while rendering into buffer 0. How is the graphics device working in relation to threads Can you work on a buffer while renderi ...Show All

• M Popiela Loading .X meshes

  How do you load a DX8 .x mesh file   My 3D modelling program (Blender) exports to DX8 format or just .X.  I don't know what the difference is. I tried it with the same code as for one of the meshes that came with the SDK, but it just gives an error. The model is a simple cube.  I am using the february SDK. I tried using the Meshviewer but it can't open them either, so I guess its just not a very good export script. I tri ...Show All

• Mar G Early Out

  Hi. I tried at the "regular" DirectX forums but since there was no answers or even faint ideas I am gonna post my question here. I have a fairly simple shader which loops over a numer of calculations. With ps_3_0 can we exit an loop and the fragment program early on if a certain condition is obtained for( ... ){ if( b > constant ) return Output; } } return Output; An alternative that ...Show All

• teacake.the.cat Transformation of a single object

  Hi! I just started learning directx and here is the first of probably many newbie questions. Please, be patient :) How can i transform a single object I used Sample Framwork to load a "tiny.x" mesh and created simple triangle. I can rotate them together (by rotating the whole world) but how can i transform only one object I've got also small problem with my "tiny.x" mesh. It's not so tiny after all :) If i move my camera, so i can see ...Show All

• ampersandz Render final scene to Texture in Shader [FX Composer]

  I want to save the final rendering of my shadowed scene to a texture (see below). I would like to know how to render to an 800x600 texture directly in the shader. I am using the FX Composer from NVIDIA. I would've thought I could simply add the following as the final pass of the shader: pass Bg < string Script = "RenderColorTarget0=TexFinal;" "RenderDepthStencilTarget=TexFinalDepthMap;" "RenderPort=;&quo ...Show All

• Iza SoftwareVertexProcessing is leaving some part empty

  I have been banging my head on the wall over my codee which doesn't seem to be working fully. I am displaying Sprite's, text, backgrounds and you name it (all 2D) on the screen, the only thing that is not working is the text. The code works on some computer and others not, which was a really big mystery to me. After some serious debug of each and every line, I found out that the code is doing it thing, there was nothing wrong with it (I am displ ...Show All

• Ashish757 Miller & Weller

  Now that our David has toddled off to Microsoft is there a possibility of a joint book between Miller and Weller  I certainly hope so, an awesome combination! Well, the "Weller" half has been at Microsoft for over 3 years now, so I'm not sure how I've "toddled off" :-) To be more specific though, I doubt Tom and I will jointly collaborate on a book, because I hate Tom thoroughly...... just kidding :-)&nbs ...Show All

• Turbosolo Why so many big structures in managed directx?

  I was told to ask this question here to get an answer: struct Caps 304 bytes struct Material 68 bytes ... These big structures are used as properties and passed here and there. Isn't this a big performance penalty I checked the generated asm code, and it seems these's no optimization to remove the overhead. So anyone knows why Just to add to what Tom has said... You really need to look at some instrumentation ...Show All

  Q1 : As far as I have understand, current version of XNA Build isn't the final one.

  I've created a model with 3ds max 5 and I've exported to .x fileformat. I used Manged DirectX to load the file and render it, but all the materials are rendered in white color.

• Crof Lighting Question/Problem

  I am attempting to light a square.  The square is made up of 4 vertices having a position and a normal.  The normal for all the vertices is pointing towards the user(0.0f, 0.0f, -1.0f).  I have applied a material with the diffuse and ambient color set to Red. I am using a directional light which has a direction of (0.0f, 0.0f, 1.0f).  If I set the diffuse color to White, the square shows up Red as I would expect.&nb ...Show All
