AI-generated summary

The current implementation only renders visible faces, skipping those blocked by cubes. An initial coding error caused back faces to be added incorrectly when front faces were in contact with air, but this has been fixed. However, there are still issues with mesh edges being improperly culled when assembled using chunks. Further investigation into the culling logic is planned. Additionally, setting the natural terrain generation height too high leads to strange gaps, becoming more pronounced at higher Y-axis values. Once these issues are resolved, the next steps include applying grass block textures and implementing destruction and placement features, followed by adding multiplayer functionality.

2025.1.24:

Currently, only the visible faces are rendered, and the faces blocked by blocks 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 resulted in 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 height for generating natural terrain 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 height increases; if set to 20480, only strips of blocks 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 after all of the above are achieved, I plan to add multiplayer functionality.
