bedrock-viz VS open-builder

You can use Bedrock Viz to get a map of your world to find command blocks. You just have to specify in the config that you want command blocks to be marked on the map.

You could run Bedrock Viz as per its instructions to see where the zombie villager is.

You can use the advanced options in https://chunker.app/ , or for bedrock specifically you can use https://github.com/bedrock-viz/bedrock-viz

As I understand, it isn't straightforward to do in Bedrock Edition. If you want a 2D map, I use bedrock_viz. You need a local web server to use the map's features because browsers no longer allow certain javascript functions to run from local files, the file must be served through a server, which is a hassle, but once you have a web server you can make the map public for others outside your network.

Another method I think I noticed (probably not, not really sure what I'm talking about) is from Hopson97's open-builder game open-builder/chunk_vertex.glsl at master · Hopson97/open-builder · GitHub where texture coords are stored in the vertex shader. Would the idea for other block types for the above method to have a 2d array of the other block types textures like doors etc? Not sure about this method cause doesn't this require a vertex buffer which the "figured out an optimization" guy says is slow. If so that doesn't seem very sustainable.

For example, in this Notch article, he discussed using trilinear interpolation to speed up noise evaluation as well as to smooth out rough parts. But I tested, and both of his problems actually came mostly from using too many noise octaves. Minecraft used 16 octaves for each noise channel, and 8 octaves for the blending noise, when just 5-6 and 2-3 would be enough. The rest of the speed problems could be solved by implementing something to skip noise evaluations when they wouldn't matter, at least above/below max/min biome height if not dynamic octave skipping. See this screenshot difference.
