Methods for optimizing THREE.js performance

I'm currently working on developing a basic Minecraft-inspired game using THREE.js.

Unfortunately, the performance of my project is not as smooth as I'd like it to be.

My approach involves using box geometry for creating voxels, but I'm facing challenges with deleting blocks when they are broken and implementing mouse picking functionality.

I've heard that combining geometries can improve performance, but this might limit our ability to remove individual voxels or utilize mouse picking features.

Are there any alternative strategies for optimizing performance in THREE.js?

Answer №1

It's not efficient to render each voxel as a separate box, even if you were to code it in assembly language.

A better approach is to organize your world into manageable chunks, such as 48x48x48 unit sections, and create a mesh that represents all the voxels within that chunk. This way, when a user makes changes, you update the vertices of the mesh rather than adding or removing individual Box objects.
