Ray tracing in excel, a user adds technology in spreadsheets

Ray Tracing, which Nvidia is driving with its new RTX cards, is a method of simulating the way light interacts with objects. Green team powered technology, and its reach is reaching unsuspected places.

A user named s0lly has successfully added Ray Tracing to Excel spreadsheets

s0lly presented his 'crazy' demo in a Reddit post. "Using my pseudo and 'real' 3D Excel models, I have made a Ray Tracing model in Excel that I hope will demonstrate the fundamentals of Ray Tracing for any of you who are interested in learning, " they say, with a link to download the sheet. GitHub calculation. It was apparently inspired by Jamis Buck's Ray Tracer Challenge.

The last step is to go to the '' screen '' tab and press 'Animate' so that the animation runs along a fixed track or “play” to control movement with WASD.

Excel doesn't seem like the best tool to demonstrate Ray Tracing, but it's funny what the community can do with some ingenuity (and a lot of free time). S0lly also created, a while ago, a curious 3D engine with Excel, you can see that video here.
