Could you build this?
Partial While rendering basic 3D cubes with CSS 3D transforms can be prompted, building a full-featured DOM-based voxel rendering engine requires sophisticated math, frustum culling, and extreme DOM performance optimization.
What it would actually take: The engine requires JavaScript/TypeScript utilizing CSS 3D transforms (`transform-style: preserve-3d`), custom camera matrices, raycasting for block picking, and occlusion culling algorithms. The hard part is managing browser DOM node overhead—without aggressive chunking, greedy meshing, and face culling, rendering more than a few hundred DOM elements tanks the frame rate.
