      • Hi all, im having about 650 polygons, rendering in the code below, the problem is that on the XBOX it runs in about 25 FPS, and hack when it gets rotated. Hope someone has a idea to how I can speed it up: private void DrawModel( Model m) { Matrix [] transforms = new Matrix [m.Bones.Count]; float aspectRatio = 640 / 480; m.CopyAbsoluteBoneTransformsTo(transforms); Matr

      • Is there a way using the sprite batch object that you can render several rectangles, but when alpha blended, it looks like the entire object was rendered first as a single opaque image, and then that image was alpha blended, such that you would never have known it was several smaller pieces assembling the final object Instead of normally seeing each rectangle blended as it overlays another rectan

      • XNA Brains; I created some code that converts a BSP file into an XNA-renderable map file. It was on the xbox360homebrew.com site. I had everything working in the code, and then I decided to port it over to the ContentPipeline. (I'm liking the pipeline more and more now). Long story short, I've run into a few nasty bugs introduced while trying to improve my code. I've found debugging to be a

      • Hi - simple problem here - I've got a cube, to which I apply a texture made from the backbuffer - so far so fairly straightforward. However I want to only use a part of the Texture2D I've created - how do I apply a texture transformation to a Texture2D before mapping it over my cube I assume this is the way to change UV coords. Sorry if this is a chump level question - I'm not quite ready yet for

      • After some fruitless searching I have found no clear answer to a multitexturing problem I have. I figure it must be so straightforward that no one has bothered to write it down. How can I apply multiple textures to a mesh, with different textures associated with different vertices My particular problem is related to a terrain engine, but I will reduce it to a simple example.

But nothing really soaks in till you try it yourself and rewatch/reread everything. What I want to know is how to do it with XNA What do I thread and how do I thread it To test it out I wanted to build 2 programs, one single threaded and one multithreaded. Th

      • XNA uses Collections for a lot of things: ModelMeshCollection, ModelEffectCollection, EffectPassCollection, ModelMeshPartCollection, etc. which results in a lot of foreach iteration in code. I recently discovered the CLR Profiler and started poking around. It appears that using foreach on these Collections results in creation of SZArrayHelper and Enumerator helper objects. Most other systems are d

But when I display the textures on an Xbox 360, I get serious color banding. These issues are most pronounced when my Xbox is set to output at 720p or higher resolutions, but the color banding is still there even
