The Matrix Awakens: An Unreal Engine 5 Experience

No, but it is a full time job. It's getting much more complicated. Here's an hour long talk on how Unreal Engine 5's Nanite works.[1] This is a huge breakthrough in level of detail theory. Things that used to be O(N) are now O(1). With enough pre-computation, rendering cost does not go up with scene size. See this demo.[2] You can download the demo for Xbox X/S and PlayStation 5, and soon, in source form for PCs. Explore 16 square kilometers of photorealistic city in which you can see a close-up view of anything. The format of assets in memory for Nanite becomes far more complicated. GPUs need a redesign again; UE5 has to do more of the rendering on the CPUs than they'd like. What they need to do is simple but not well suited to current GPU designs. It's such a huge win this approach will take over, despite that. New game engines will need to have something comparable. Maybe using the same format. Epic doesn't seem to be making patent claims, and the code for all this is in the Unreal Engine 5 download. (Basic concept of how this works: A mesh becomes a hierarchy of meshes, allowing zoom in and out of on level of detail. The approach to subdivision is seamless. You divide the mesh into cells of about 20 triangles. Then, each cell is cut by one or two new long edges across the cell. These become the boundaries of a simpler cell with about half as many triangles, but no new vertices. The lower-resolution cell has no more edges than the higher-resolution cell. There's a neat gra
