GreedyMeshing
GreedyMeshing is a rendering optimization mod for Fabric 1.21.11 that experiments with greedy meshing techniques for chunk geometry generation.
Overview
In vanilla Minecraft, block faces are typically generated individually during chunk mesh building. GreedyMeshing attempts to merge adjacent faces of the same block type into larger quads during mesh generation. This can reduce the number of faces generated for flat or uniform surfaces.
For example, a flat wall made from many identical blocks may be represented by fewer quads when possible.
Features
Greedy meshing algorithm Uses a sweep-based approach to merge adjacent block faces during chunk mesh generation.
Experimental performance optimization In some scenarios, reducing the number of generated faces may decrease geometry complexity and GPU workload.
Debug tools Includes a wireframe/debug mode for visualizing generated chunk meshes.
Compatibility
- Designed for Fabric 1.21.11
- Because it modifies parts of the rendering pipeline, it may conflict with other rendering or shader-related mods.
Status
This project is experimental and intended primarily for testing greedy meshing techniques in Minecraft’s rendering pipeline. Performance improvements may vary depending on hardware, world geometry, and mod combinations.
