If you can, do the picking on the CPU by calculating a ray from the eye through the mouse pointer and intersect it with your models. If this isn’t an option I would go with some type of ID rendering. Assign each object you want to pick a unique color, render the objects with these … Read more
You install a system wide hook. (SetWindowsHookEx) With this done, you get to be loaded into every process. Now when the hook is called, you look for a loaded d3d9.dll. If one is loaded, you create a temporary D3D9 object, and walk the vtable to get the address of the EndScene method. Then you can … Read more

The way they do this is by editing the d3d/opengl DLL at the process memory level, like injecting assembly jumps. I know this because their method was causing my mod to crash, and … Read more
If you’re actually good at writing unmanaged code, then you’ll probably be able to write a faster graphics engine on top of DirectX. However, for the hobbyist, XNA has plenty of performance, both for 2D and 3D game development. Here is a good Channel 9 video where they run an XNA-built racing game on Xbox … Read more

It organizes the still-usable ideas from other posts and adds a few novel ideas. None of this behavior is at all documented on Microsoft’s … Read more
The model, view and projection matrices are three separate matrices. Model maps from an object’s local coordinate space into world space, view from world space to camera space, projection from camera to screen. If you compose all three, you can use the one result to map all the way from object space to screen space, … Read more
