      • Hi, I'm still trying to draw large gridmap terrains on the 360 and so far am having a lot of success. Performance seems to be a lot higher than my 6800GT, perhaps by about a factor of about 4. The issue I'm having though is really rather strange and I've been wondering for the last couple of hours quite how it could be happening. I create a huge vertex buffer (as big as XNA allows before thr

      • Hi all. First of all, I'm new to DirectX. I'm trying to load an image into a PictureBox component (C#) using DirectX. The problem is that I'm working with large pictures (for ex. 4021x3123) and can't use the Windows GDI, because the picture takes a lot of memory and it flickers when I move the scrollbars. That's why I was thinking of using DirectX. I've linked the DirectX Device with the PictureBo

      • Something strange is happening in my ConvertMaterial override. Here's my build process in pseudo code: I place the normal texture in the same directory as the diffuse texture with a simliar naming convention (eg. diffuse=BumpWall01_rgb.png normal=BumpWall01_nrm.tga) My ConvertMaterial override scans the directory of each diffuse texture it converts to find whether it has a normal file.

      • I'm trying really hard to enjoy XNA. It seems like a clean break from native programming. I enjoy the innovation that MS gave, but maybe its just their docs that are just annoying right now. I read the docs and when I try to follow something on the Windows development side, it goes right into the XBox code and doesn't give me the source code I need for Windows. I thought I was reading a

      • I've created a basic skybox by building a box out of 6 basic vertex buffers and loading a 2d texture onto each one, and placing the camera in the middle. I am assuming that this texturecube enables you to do this better, but the help documentation doesn't really define what this is. Thanks for the help.

      • I'm just surprised to find that XNA is using clockwise vertex ordering by default. Well, when I'm told it uses right-handed system, I thought it should be counter-clockwise just like OpenGL with no doubt. However, after double checked, I'm sure it is clockwise, the same as old DX. So now there will be a new widely used convention created: right-handed but clockwise vertex ordering. All I want to s

Identical code on the XBox 360 shows no difference in calculation speed. Does the XNA Framework actually distribute the processing, or is it serially multitasking on a single core
