The obvious next step is to read chunks from disk and generate geometry for them... which is going to be a bit annoying so I might put it off for a bit.

Expanding the renderer a bit more. Some placeholder for water that looks less ugly than before, better transparency support in general, and I've stopped generating meshes for occluded faces. Generating geometry in about 2ms on this machine which is close enough to my performance goals for nowSwapped out my GPU earlier which is why this dropped to 30 FPS while recording, the performance is still fine

It took me a long time to realize that the "temperature" that goes into the sky color calculation was not the "temperature" of the biome itself but rather the "temperature" of the noise function that Minecraft uses to pick the biome. Also it's *not* HSL, it's HSV.

Some stuff to look forward to nearish term:- Models for stairs, "twoquads" (e.g. flowers) and "onequads" (e.g. ladders)- Animated textures- Finalizing the lighting system and day/night cycle- Stars in the night sky- Particle effects for e.g. torchesAfter that it will probably make sense to pause rendering to flesh out the chunk manager and connect it to a server

Had a lot of Real Work to do today so that's probably all for betamine today. Tomorrow I might do "onequads" (like rails and ladders) and set it up to fetch chunks from regions dynamically (and explore the whole world).

Terrain renderer's back, now integrated into a dynamic chunk manager!Watch that FPS counter drop like a rock -- there are still a number of performance improvements I have to do (e.g. frustrum culling) and chunks are never actually *un*loaded once loaded

Added some key performance indicators to the debug overlay: (C)hunks rendered, (V)erticies rendered, and the ratio (V/C). The goal is to bring all of these number down.63M verticies is entirely too many for the scene shown here -- the tesselator needs to find more opportunities to reduce the V/C count, and frustrum culling needs to reduce the number of chunks rendered as well.

For culling I'm going to start with culling entire chunks but I have a few reasons to suppose that splitting chunks into 16x16x16 cubes would have performance gains in frustrum culling but also in a few other places as well, like re-tesselation when a chunk is changed (e.g. by placing/removing a block)

Back up to a more reasonable framerate with unloading of distant chunks and frustrum culling in place (note C is given as a ratio now)However, lots of verticies still need to go by making chunk tesselation aware of neighboring chunks (and not unconditionally rendering faces on chunk boundaries).

Happy enough with this performance to move on from optimization for now, but for future reference I have noted a few low-hanging fruits: splitting chunks into smaller pieces (16x16x16 being obvious) for better frustrum culling and faster tesselation updates; reducing the size of vertex attributes and offloading some additional computation to shaders; and possibly moving tesselation off of the main thread

Oh, and at some point I plan on reducing the average tesselation load by caching more tesselated chunks than are actually being rendered, so that the tesselation distance exceeds the render distance under normal conditions

Implemented chunk re-tesselation, performance is quite good. FPS about double that of vanilla Minecraft on my machine. Here's a short video walking around my test server near sunset for your enjoyment.I removed the ability to run betamine without connecting to a server, so all future screenshots/videos will be of betamine connected to a vanilla Minecraft server (until I implement a server myself).I think #harelang is pretty good for game development 😃
