Realistic Snooker Ball Path Overlay

The goal is to create a lightweight 2-dimensional overlay for Snooker 2009 on www.gamedesire.com that draws a single, continuous and realistic-looking line predicting the cue-ball’s trajectory and, if possible, the cue ball I'll pot. Only the path itself matters—no speed, spin or other data—so the graphic can stay clean and unobtrusive. A “basic line” is enough; it just needs to blend naturally with the game’s existing visuals rather than appearing cartoonish or overly stylised.

I will launch the game in either windowed or full-screen mode and toggle the overlay on demand, so the solution has to sit transparently above the DirectX/OpenGL render (or use any other viable technique) without modifying the original game files. If reading game memory is impractical, a computer-vision approach is fine; whichever method you choose, the result must feel native and lag-free.

Deliverables
• Executable (and, if possible, source code) that renders the real-time trajectory line during live play
• Simple keybind or UI switch to show / hide the overlay
• Brief setup guide covering dependencies, installation and usage

I will test by breaking, lining up a few straightforward shots and confirming that the overlay predicts the ball’s path accurately and stays in sync throughout a full frame.
