I guess you know what Octrees and Quadtrees are so wont go into too much detail on them here, but they are basically a great way to hold static (none moving) game objects in groups for the use of culling and the like. As stated this is great for game objects that don't move, terrain, buildings and...

[youtube]http://www.youtube.com/watch?v=1ajrL-iORZk[/youtube] Well here is my rolling fog. The sample download has two projects, one for XNA 1.0 Refresh and the other for XNA 2.0. I got it up and running on my 360, but for some reason on there the textures got mashed, the fog was fine though. I will...

[youtube]http://www.youtube.com/watch?v=_sx0KDO-ZbA[/youtube] Well as mentioned in my previous post, here is the 3D particle system again only this time the particles are scaled. Now I didn't think that you could scale pointsprites, but it turns out you can :P I found out after going to an XNA meeting...

[youtube]http://www.youtube.com/watch?v=1WAP0em8Zzk[/youtube] I have altered the shader a bit since my last post. I now only use a single cloud texture, sample that three times and rotate each sample over the other and add the result to the sky color. I have done this as passing more was having an impact...

Well this is the source post for my terrain and road map stuff. I will briefly describe what I have added and then onto where the source download is. So all I have done is add another Vector4 to the vertex element that holds the weight of the given road texture to be drawn. This then needed a new string...

I know, how many times can a guy extend a terrain class!!!!? Lots I guess, this extension to the class and shader adds another map image that I call a road map. As you can guess this image holds a map of where I want to draw roads on my terrain. It is made up of four colors, Black (no road), Red (road...

I am posting the source to this now as I have a project at work that is going to take up my time over Christmas and into the new year and also have to start studying if I am going to get anywhere with my Microsoft Certification :( I am not going to have chance to add any more to it. So this is the project...

I guess this started out as a bit of a toy. Using my old skybox code, I thought it would be a good idea to have the shader manage the lighting of the sky, you know have like a nice sun rise/set, have the color of the sky slowly change over time. But as I was using a box it meant that you got some corners...

Well thanks to Ultrahead and his blog he gave me, I have been able to put this example up of a OOBB (Object Orienated Bounding Box). Using the same code from the last project I have added the source from Minh at Channel 9 . Took me a while to get it integrated as he is creating the roataiton from a vector...

[youtube]http://www.youtube.com/watch?v=mqVB8BmVTYc[/youtube] The idea for this post came from a thread I spotted on the XNA Creators Club Forum . I read in the thread that you can't have your bounding box's rotate, now when I debug my collision stuff I tend to draw my bounding box's so I...
