I’ve built a cavern generator, and then put together a simple space partitioning thing to fill a world with caverns Next come the interconnects between caverns!
Here’s a shot of what it looks like – this is a lot smaller than it will be, the world is only 800×800 pixels in this image. The procedural generation will produce approximately the same set of caverns regardless of scale though – I’m pretty proud of it.
(I’m using my desktop rendering windows for debug windows in this entry 😛 ah well, maybe next LD will give me an opportunity to use them to their full potential)
