For creative sandboxes, one recurrent favorite topic is starships, airships and ships in general. It would be very cool if you could actually fly or sail them and, while you do so, continue to build and destroy them.
The clipmap system currently in Voxel Farm sees the entire world as a single monolithic entity. While fragments may be detached from the voxel world, they are kept as meshes and optionally voxelized back into the world when they stop moving.
We are working on a new system that breaks the scene in not only one clipmap, but as many clipmaps as necessary. Here is a video showing the basics of how this works:
The video uses spheres for simplicity. The key here is that each sphere is an object that lives in a different clipmap.
Just like with a single clipmap, portions closer to the camera will get greater resolution, but very unlike the single clipmap, these entities now can be moved around and placed at any arbitrary position, scale or rotation.
Even if the camera is not moving, a given entity may be moving respective to the camera. If the entity approaches it will get higher resolution representation.
I look forward to building a castle, lifting it with massive zeppelin-like devices and exploring the world while comfortably sitting next to a fireplace. Pretty much like Pixar's Up, but with siege weapons.
