      • I'm trying to create references to .fx files from my Content Pipeline types (my writer). When I build my level objects, I want the references to textures and effect files to be baked into the object so that you don't have to add .fx and .png files to your project, just add the file that processes into a level. (A .bsp in my case). My problem is that I used this thread to create external referen

The hexagonal plane mesh will be rendered with a texture (grass, road, water, etc) and 3d objects (buildings, characters) will be rendered above the tile.

      • Hello... I'm writing an app in native C++/win32. It has a complex GUI that I have created with bitmaps. Since it has to be very fast I'm thinking about making it using direct3d (or Directdraw). I don't want to use controls, just a window where I paint in it's client area. Do you think I can have performance increasing over GDI If so is it better to use direct3d or directdraw Thanks!

If they don't, I want to display a message to that effect.
