- I wish someone would remake this weird game from the C64 that has stayed in my head since forever: Scarabaeus https://www.youtube.com/watch?v=FusuIst21E4by Scapeghost
- Ah yes, Lode's raycaster tutorial, the classic writeup keeps generating interesting projects. Such as this one.
The human ingenuity never ceases to amaze me. Take what's essentially a pong machine with a few extraneous bits and almost no memory, what you can do with it? Apparently racing games, building games, maze games, even honest to god space sims.
by krige - This looks very similar to the Doom fire algorithm (later), except that one is applied to a fixed buffer over and over again every frame.
> it is tempting to view the algorithm as based on cellular automata (Sarkar 2000), yet the lack of parallelism and the strange shape of the 'neighbourhood' of cells surrounding X makes the cellular-automata notion contrived.
If you consider rows as time then dependence is local rather than global. It looks like a 2D automata with a temporal neighbourhood component. And IMO asymmetric or nonuniform neighbourhoods dont necessarily exlude it from the definition, but affects its classification.
Does anyone with deeper academic overview of CA have any insight here? I find many things can look like CA if you stare at it right, but am never sure where to draw the line (maybe there isnt one)
