As one of the most successful and popular toys, LEGO bricks have great appeal to both adults and children. But there are so many kinds of LEGO parts, it is not easy to store and manage so many parts and freely build the creations in mind. So back in 2002, LEGO started developing LEGO Digital Designer, whose original vision was to allow people to build bricks on a computer, have fun and share their creations.

Voxel (short for voluempixel) refers to the smallest unit of the world that is made up of objects rendered in three dimensions, which can be cube, sphere, cylinder and many other basic geometries, as well as the iteration forms of complex geometry. When it comes to voxel games, the representative work is of course the well-known sandbox game Minecraft, in which the entire game world was created using voxels.
