What This Means for Your Design

Imagine building a 3D model of a construction site, but instead of just surfaces, it's made of tiny, smart cubes (voxels). These cubes know what material they are, where they are, and how they should behave. This makes the model super accurate for tracking progress and simulating how diggers and trucks will interact with the ground, especially when the ground is constantly changing.
