 ### `//floodfill [<replace_node> [<radius>]]`
 Floods all connected nodes of the same type starting at _pos1_ with <replace_node> (which defaults to `water_source`), in a sphere with a radius of <radius> (which defaults to 50).

+### `//ellipsoid <rx> <ry> <rz> <node_name>`
+Creates a solid ellipsoid at position 1 with the radius `(rx, ry, rz)`.
+
+```
+//ellipsoid 10 5 15 ice
+//ellipsoid 3 5 10 dirt
+//ellipsoid 20 10 40 air
+```
+
+### `//hollowellipsoid <rx> <ry> <rz> <node_name>`
+Creates a hollow ellipsoid at position 1 with the radius `(rx, ry, rz)`. Works the same way as `//ellipsoid` does.
+
+```
+//hollowellipsoid 10 5 15 glass
+//hollowellipsoid 21 11 41 stone
