Neural Networks Using Doom Level Creator Like It’s 1993

Readers of a certain vintage will remember the glee of building your own levels for DOOM. There was something magical about carefully crafting a level and then dialing up your friends for a death match session on the new map. Now computers scientists are getting in on that fun in a new way. Researchers from Politecnico di Milano are using artificial intelligence to create new levels for the classic DOOM shooter (PDF whitepaper).

While procedural level generation has been around for decades, recent advances in machine learning to generate game content (usually levels) are different because they don’t use a …read more

Hack Excel for 3D Rendering

[C Bel] teaches Excel and he has a problem. Most of us — especially us Hackaday types — immediately write a VBA (Visual Basic for Applications) macro to do tough things in Excel. Not only is this difficult for non-technical users, but it also isn’t as efficient, according to [C Bel]. To demonstrate that VBA macros are not always needed, he wrote a 3D game engine using nothing but Excel formulae. He did have to resort to VBA to get user input and in a very few cases to improve the performance of large algorithms. You can see his result …read more

Doomed Incandescent Light Blinker

[Jānis]’s entry for the Flashing Light Prize was doomed from the start. Or should we say Doomed? It was a complicated mess of Rube-Goldbergery that essentially guaranteed that he’d have no time for making a proper video and submitting and entry. But it also ran Doom. Or at least ran on Doom.

(Note: [Jānis] sent us this hack in the e-mail — there’s no link for this blog post. You’re reading it here and now.)

It starts with a DC motor salvaged from a DVD player that spins a wheel that flips a switch back and forth, which in …read more
