They mean, "this location has a recognized pattern of walls/floors/ceilings." I define the patterns I care about in data, and the system assigns a random color to each one.

For example, there's a unique color for "walls on all sides, no floor or ceiling; i.e. part of a vertical shaft".

No doubt. The PCGEx library has some great pathfinding that supports waypoints and I have a toy setup that let's me create point actors in a volume and solve a route through them.

I can also see it informing content synthesis algorithms like WFC.

I also want to see if I can aggregate it to better reason about interesting topologies, e.g. "this is the start of a bottomless pit that extends 12 cells downward," or "these locations could accommodate a prefab of size x/y/z".

I think I want to use it to inform placement of environmental decorations, interactables, and metadata volumes that will influence PCG generation at those locations.

Been working on how to tease interesting environmental data out of my dungeon generator, like whether a location does/not meet certain criteria for nearby floors and walls. #procgen #screenshotsaturday #unrealengine #pcgex #dungeoncrawler

There are lots of gamers who love game developers, too.

Adapted some of PCGEx's pathfinding algorithms to my dungeon's corridors, which are more rectilinear now and feel more structural. #ScreenshotSaturday #DungeonCrawler #PCGEx #UnrealEngine #procgen

IIRC Dreams solved it by packing volumes with spheres, based on a technique published by NASA(?). You could actually see a brief visualization of it if you tweaked an object's physics accuracy.

Really slick. For the visualization, did you roll your own solution for "morphing" between the steps?

My favourite thing I heard of like this is a debugging feature in Alien Isolation where instead of hissing the Alien states aloud what it's thinking about.

"I heard you. I am hunting you. I am hunting you. I am hunting you. I have found you."

This is cool to see; this β€œroller spline” approach is how we modeled deformable half pipes in THPS Remastered Create-A-Park. We also had to solve lots of math knots.

What workflows do you think have the biggest gaps? Modeling? Blockout? Environment art? Lighting?

The morphs in Keeper use distance fields as an (implicit) surface representation, which makes it possible to control the distance at which the surface should lie. In other words, it’s easy to deflate or inflate objects, and meshes become easily β€˜moldable’.

Made it to Ultimate Vault Hunter level 5 in #Borderlands4, the first time I've ever reached max endgame in a Borderlands title. Maybe now I'll get back to the other games on my backlog.
