      • Hi, I've read a few things about needing to load up all resources up front, and avoiding dynamic loading in order to keep performance up - if that's true I guess it applies to mid-game loading and not per-level loading I'm used to using various states to load up resources (e.g. models etc.) for a level, then play the level and when we trash the level (either quit/die/finish-level etc.) we trash t

      • Apologies in advance if this question has been covered elsewhere. I've searched through literally hundreds of posts here, but couldn't find anything relevant to my issue. I'm working on some code to simultaneously display a 3d model from several different camera angles in several different viewports. Unfortunately, I've run into a rendering problem whenever I draw the model in a viewport. For refe

      • Hi, I was just wondering, what is the easiest method of generating tangents for use in xna I recall there being a function in the mdx(or maybe dx C++) that could generate tangent based on a set of arbtiary vertex data. Does Xna have this If I have to manually create them, are there any C# samples for doing this Even if it's not for xna, I can always port.

It doesn't exhibit this behavior on the pc solution and they are using all shared components so the code is identical. It seems ok when I run it without debugging. Any ideas

I can't push code to my Xbox 360 from GSE.  This issue has been reported by other people and their problems boil down to either having entered the 25-digit code incorrectly or, in one case, that their router didn't properly support UPnP.

      • I think I'm being dense today, but I can't figure this out for the life of me. I have a model that I want to rotate across the X and Y axis. My issue is that when I rotate across the Y axis, I always want the rotation to occur as if the axis was vertical in terms of world space. If I multiply by my X rotation first, obviously the Y axis moves with it, so rotating about the Y axis will rotate it ab

      • Just me, or are the models used in spacewar needlessly huge in dimenisons and in vertex count In wireframe render mode it's easier to see - the ones with gun barrels that have cooling holes are individually modeled that way - it's not like you can see that level of detail. The flying saucer one has an enormous number of verticies can could have been welded away. I haven't seen anything as to

If for instance I wanted a plane located at 0,0,0 and is pointing straight up (+Y ), what would the correct values be for the constructor The d component I ASSUME(probably wrong) is the distance from world 0,0,0.
