The current progress includes rendering only visible faces, skipping those blocked by cubes. An initial coding error was corrected, which caused an issue with rendering back faces when front faces were exposed to air. After fixing this, the rendering appeared normal, but a new problem arose with mesh edges being incorrectly culled when viewed from below. The plan is to investigate the culling logic further. Additionally, setting the Y-axis height for natural terrain generation too high creates odd gaps, becoming more pronounced at extreme heights. Once these issues are resolved, the next steps will involve adding grass block textures and implementing destruction and placement functions, followed by multiplayer capabilities.

2025.1.24:

Currently, the effect of rendering only visible faces has been achieved, and the faces blocked by cubes are skipped in rendering.

The code condition was written incorrectly the first time; it checks if the front face is in contact with air, then adds a back face.

This led to this appearance.

After fixing it, it looks more normal.

However, there is still a problem that I don't know how to handle. After I used chunks to piece together the meshes, it looks like this from below. I don't know how the edges of each mesh were culled on these four sides:

Currently, I plan to investigate whether the culling logic needs to be modified.

Also, if the Y-axis limit for natural terrain generation height is set too high, there will be some strange gaps, such as the various holes in the image below: Y = 320

This situation becomes more pronounced as the Y-axis increases; if set to 20480, only strips of cubes remain, and the terrain is no longer visible.

After fixing it, I can try applying the grass block texture to see what my world looks like with only grass blocks.

Additionally, I need to implement destruction and placement functions, and plan to add multiplayer functionality after all of the above are achieved.
