• SDavis7813 mipmapping

  Hi, i've loaded some fbx models via the content pipeline with integrated textures. can i tell the loader routine to auto-generate mipmaps when loading textures integrated in fbx models or how can i postgenerate the mipmaps out of the models. sorry for my english ;) thx #pragma oh ok :) thank you The content pipeline will create mipmaps by default: you only need to do anything special if you don't want them to be generated for you. It will create all the way down to a 1x1 size. There's very little reason ever to do anything other than that, because the last few mipmap levels occupy almost no memory compared to the full texture and first mip, so once you've paid th ...Show All

• LeahGarrett Why my Device is slow than SDK

  Hi everybody, I want to build a simple directx form (window), but its so slow. I have some examples from "Direct3D sample from DirectX 9.0 SDK April 2006". They are super fast and i dont want to use "DXUT Units" (I want to create my own window and stufs). Here is my code (in Delphi): ////////////////////////////////// var D3D: IDirect3D9 = nil; D3DDevice: IDirect3DDevice9 = nil; function InitD3D(hWnd: HWND): HRESULT; var d3dpp: TD3DPresentParameters; begin Result:=E_FAIL; D3D := Direct3DCreate9(D3D_SDK_VERSION); if (D3D = nil) then Exit; FillChar(d3dpp, SizeOf(d3dpp), 0); d3dpp.Windowed := True; d3dpp.SwapEffect := D3DSWAPEFFECT_DISCARD; d3dpp.BackBufferFormat := D3DFMT_UNKNOWN; d3dpp.EnableAutoDepthStencil ...Show All

• LRA HLSL - do all my matrix math inside shader?

  Hi All, Just getting into HLSL, and was wondering if someone can advise if there's any drawbacks or problems doing my matrix math inside the shader, like world * view * projection, offloading it from the CPU. Specifically, I want to pass in my world transform matrix for the object into the shader, and have it do: objectWorld * commonView * commonProjection thx, p. That's actually a bad thing to do on the shader, because it will be executed again and again for each vertex (or pixel). Actually, if you do this with a modern DX SDK, the HLSL compiler will take out these calculations and turn them into pre-shaders that are executed on the CPU once prior to sending the results as constants to the GPU.

  Hi, I am trying to compile a DX10 program with a LCC based C99 compatible compiler. It works fine with DirectX 9, but with DirectX 10 I get an error message in the dxgi.h header in line 287 that says: "Missing Parameter type '__RPC__deref_out'" This error repeats then a couple of times, because it is quite often in the file. In d3d10.h I get an error message in line 865 saying: Syntax error: found 'ID3D10Device' - expecting ')' and missing parameter type __in later in line 879 I get a "Duplicate field name 'guid' in [incomplete] struct ID3D10DeviceChildVtbl' ... and there are others as well. If there is a way to fix this easily in my headers, I would appreciate your advice, - Wolfgang ...Show All

• Wil Burton Serializing CustomVertex

  Microsoft.DirectX.Direct3D.CustomVertex is not marked as Serializable, so an array can not be Serialized. Is there any way to overcome this Thanks. Your array of vertices will be of an specific type, not only CustomVertex but CustomVertex.PositionNormalTextured or something. CustomVertex is nothing more than a static class storage for all that bunch of pre-defined structures of custom vertex specs, and a struct of basic types (as in the case) is indeed serializable. Hey man! please stop laughing at the people who’s trying to help you. After all, It is you who is asking for help. Have your extra intelligence ever put it’s hands on the fact that the CustomVertex is just an st ...Show All

  How can i obtain extra information from a File using Content importer Now i already have made a content importer for my ownfile format, that is ok because i se the importer to extract the texture Infromation from my file...

• yjacket2006 Animation Transform Question

  Hey, in XNA I am doing animation by  finding a bone's final transform for a given animation frame. I do this by first finding the transform of the bone for that frame through interpolation or direct keyframe data, then finding the absolute transform of the bone for that frame, and finally multliplying it with the matrix that transforms a vertex to the local space of the bone. Since the bind pose in XNA is stored in the bones, unlike in directx, I get it by multiplying the absolute mesh transform by the inverse absolute bone transform. This seems to work fine for all .X files, but for .FBX files, it seems to not work sometimes. Is this algorithm not compatible with .FBX files, or is this probably a bug in my code/invalid fbx file ...Show All

• Delphieur TorqueXNA

  I had a look at the XNA version of the Torque 2d engine and noticed that it converted 4mb worth of png files into over 60mb of xna files; Is this a Torque issue or xna as its a massive increase and would make releasing any games online a virtual impossibility. The Tank Buster starter kit has a little under 10MB of png files that turn into 87 MBs of xnb's. Thanks Shawn, but I'm not sure if that answered the question. For example, I have a splash screen that goes from 5.21kb in PNG format to 1.10MB (1126.4kb) in XNB format - over 216 times bigger. Is there something I have to change in the properties for that file to keep it from getting inflated It's not Torque that's doing it. It uses the d ...Show All

• Florian 0. Saving backups, refactoring, & other newb questions

  Hi, I have a specific, minor question, and a general, major question. :) First the simple question. Is there any way within GSE to save a backup or earlier version of the file you're modifying, other than simply to "Save As..." I dimly recall that Word has some sort of version-saving feature; does GSE or VS have this I actually find it easier to use Windows Explorer to copy the file to a new folder, but that seems kludgy. Now the bigger question. I'm fairly new to coding, and while I can get things to work, I don't love the style in which my code evolves. I try my best to create classes and objects to do relevant work, and I try to keep methods short and specific. Still, inevitably I seem to end up with one class with ...Show All

• GAtkins Best coding practises with ContentManager and GraphicsDeviceManager ?

  I hope someone can give me a decent explanation of this as it's something which I would of thought is pretty essential to writing anything in GSE but makes no mention of it in the documentation. I'm trying to understand the best way for any game elements to access the main games graphics and device, these need to be written in a way that I can give this routine to someone else and they work without the other person having to hard code aynthing in the code I give them. I believe there may of been a more obvious way to do this in beta 1 but I picked things up from beta 2 so some of the examples and documentation is referencing things which have since been taking out. My main confusion comes from the differences in the Windows Game and Spacew ...Show All

• Pixelpands Content Pipeline Assembies

  So I created a separate project to hold my custom importers, and added that to my game project's list of "XNA Framework Content Pipeline Assembies" (Project Properties > Content Pipeline). Here's my problem: the 'Configuration' and 'Platform' drop downs are greyed out (disabled) so I can only add one reference to the project and have to choose to add either the Release version or the Debug version. I've got the importer library setup as a dependency of the game project, so if I make a change to my importers, it automatically recompiles them first, then compiles the game (repacking the content with the new assembly). The problem though is if I add the Release assembly to my game project, but have the solution set to Debug, i ...Show All
