• Advait Supnekar Rotation matrix: absolute rotation instead of relative?

  Hi, When multiplying rotation matrices for rotating around x, y and z-axes R = Rx * Ry * Rz ( http://en.wikipedia.org/wiki/Rotation_matrix ), I get a relative rotation matrix, meaning that rotation around Y is not the original Y-axis, but the new axis that has "occured" after rotating around X. What I want to do, is to have absolute rotation, so that the Y-rotation is performed around the original Y-axis, and not the new one (abs ...Show All

• LJry 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

There ya go, PIX , XACT , XInput , OK fair enough, but this isn't really what people are waiting for when they talk about XNA. CDX/CDXUT , DXUT/DXUTGUI.... also the n ...Show All

• BavBoy Pixel shader 3.0 constant indexing

  Hi. I wanted to perform some deferred shading using pixel shaders 3.0 and DirectX 9.0c in a GeForce 7800. All was fine until I tryed to change the "stencil light volumes" for an unique pixel shader... Noticed the FXC ( effect compiler ) has two HEAVY problems: 1) Doesn't allow texture arrays. For example, you cant do "shared texture tex [ 8 ]". 2) Doesn't support pixel shader constant indexing. Surfing the Internet I found this http://www.o ...Show All

• FollowerOfTheWay DirectX Area inside a CLR/WFA or MFC window?

  Hello! I'd like to write an application which should use DirectX, but not in the whole window, only a part of the window. In the other parts of the window there should be buttons and input areas to controll what is happening inside the DirectX area. So appart of the DirectX part, that looks like a normal CLR windows forms application or a MFC application. My questions are: Is it possible to include such a DirectX area in a windows forms applic ...Show All

When I try to resize the rendering window, The resizing operation was too fast and catching up my mouse pointer inspite of it's speed, This is good. But this happens only in Debug or in Release mode while Visual Studio is open!!. If I closed the ...Show All

• Jair Priori Minharo Junior Forms.Keys vs DirectInput

  I know its probably just me, but is there any reason that OnKeyDown can only process one key down at a time I should add that I am used to using DirectInput for this kind of thing, but I see that it's being recommended not to use it any more, so I tried using OnKeyDown, but when I hold down 2 keys at once, only one gets processed even though my code looks like: if (e.KeyCode = Keys.W) moveforward(); if (e.KeyCode = Keys.A) moveleft(); ...Show All

• GradyMeng Paint Texture

  hi, in my game i want that some pc screens show dynamic graphics, there is a way to paint lines, points, texts, or other sort of things in the texture how There are a few methods you should check out: 1. Render to texture - you can rener 3D geometry to the texture instead of to the screen, and then use the texture in a subsequent render. 2. GDI - you can get the texture's surface and then use GetDC, which you ...Show All

• Damir Dobric 'culture demo from GDC2006

  @ the Microsoft booth last week, GDC 2006, a small cellular automata game called 'culture was on display. It was described as "a visually stimulating 3D floral simulation of cellular automata." This was apparently a promotional project to show how fast a C++ programmer could learn C# and the XNA framework and produce something visually interesting. I found this small XNA application to be a beautiful interactive toy, and would enjoy ha ...Show All

• Avitus Unable to load Microsoft.DirectX.dll in Visual Studio 2005 Pro Ed

  I recently installed Visual Studio 2005 Pro Ed.

• Teo DirectX Versioning

  Hello, I have heard a lot of talk about "which version of DirectX that is going to be used as" DirectX 9.0b, c, whatever. The problem is that through all my research I see no indication that the SDK coresponds to a version a, b, or c at all. It seems to me that SDK versioning is dependent upon release date, for example, DirectX SDK December 2005, whereas the a, b, or c only indicates the runtime version and has absolutely nothing to ...Show All

  I can not see the MC2 Editor being part of the XNA project. When I build/rebuild MC2 the editor files are not updated. What do I do wrong or How can I make changes and updates to the MC2 editor Sorry for the really long delay with this but I have the proper solution now. In EditorInterface.cpp go to line 1734 you should see this line of code: TCHAR *curDirStr = new TCHAR[curDirStrSize]; C ...Show All
