      • Hello! My application reads information from an OPC server. Each model is a cylinder (Standard Primitives) I have made 1 basemodel of the cylinder that i change the height and radius in runtime by scaling it. My problem is that when the application first time gets information from the OPC server it contains only one cylinder, 2min later it could be 30cylinders. The number of cylinder

      • Hello everyone! I'm rather new to the XNA as well to this Forum, so please don't neglect my tricky thinking and poor language usage abilities :D. I want to take adventages of Content Pipeline, but I'd like to simulate it's work in runtime. I tried to understand the internal mechanism using Reflector, but the code unsuprisingly overhelms me.

I'm currently rewriting Quake 1 in XNA and I got he levels to load fine but its deadly slow. I do not use the vis yet so I render everything but its still should be pretty fast. If i render the level using only a single texture2d its pretty damn fast but for using multiple texture what

      • Before I started using a Z-buffer, I was able to render Jpeg and Bitmaps as textures; instead of using TGAs. Using a 16-bit depth buffer, the bmp and jpg textures appear as vertical strips (hard to descrive) and some of the tga textured materials appear a little jagged round the edges. However, using a 24-bit buffer, the tga textured materials appear nice and smooth... but, the jpg

      • 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
