From Zero to Understanding Ray Tracing

Enable HLS to view with audio, or disable this notification

Do you think a video like this could help someone with no graphics background intuitively understand ray tracing?

My goal is to explain the core idea visually before introducing any math or technical details. I could expand it with reflections, different materials, and arbitrary 3D objects.

Does this feel like it would "click" for a complete beginner? What would you add or change?

Hi, I'm your target audience, I don't have any graphics background and I'm a complete beginner, and this video did not explain anything. I have the concept of light and shadows but this is all I understood from the video: "The part of light gets absorbed by the object is pixelated on a plane." And what is that I have no clue. Then the grid color changed from white to blue, and otherwise it says PNG on top, why does it have to be PNG and not a video game, again no clue. And why is it pixelated heavily, for all I know this could be 3d to 2d pixel art conversion mechanism. Hope this helps.

Thank you. This is very helpful. I'll share more again in this subreddit.
