      • Hello, I have an application that has a function that emulates the DrawPrimitivesUp() function without actually calling DrawPrimitivesUp() for educational/debug purposes (it actually does the vertex shading and outputs the vertices to see whether they're correct output). In this function, this is what I do (input parameters are parameters to DrawPrimitiveUp): 1. Get the FVF via GetFVF() and store

      • 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

      • Hi. Still working on my 3D playing cards class. I know how to set the textures of the front and back of the card independently now, but I don't know how I can use a single texture sheet (comprising of 52 fronts of cards and a few back face images) in this process. The BasicEffect takes a Texture2D format for the texture, and of course setting it to a single texture image is fine. But how to set th

Sticking with the game component idea for the moment, all the objects in my scenegraph are currently DrawableGameComponents. Using the nifty XmlSerializer class I can easily store my scene graph with all its children and load it at a later time. However, this requires every class being seriali

I'd like to be able to dispose of the one large terrain texture image and use tiling and different layers for different tiles. (Texture splattering, I think this is called). However, for now I'll be happy with just tiling m

In every example I have seen, the world, view, and projection matrices must be assigned to each effect of each mesh of each model, each frame. For a scene with say, 100 models, this could easily result in tens or hundreds of thousands of completely
