View Patent ↗A system for rendering virtual terrain includes an Internet-connected server and software executing on the server from a non-transitory physical medium, the software providing a first function for building a basic terrain from geometric blocks, a second function for analyzing surrounding terrain properties, a third function for adding or subtracting blocks from the terrain, and a fourth function for smoothing the final terrain surfaces.
1. A system for rendering virtual terrain, comprising:
an Internet-connected server; and
software executing on the server from a non-transitory physical medium, the software providing:
a first function for building a basic terrain from geometric blocks;
a second function for analyzing surrounding terrain properties;
a third function for adding or subtracting blocks from the terrain by at least analyzing the surrounding terrain and selecting blocks to add by appropriate shape and orientation for placement; and
a fourth function for smoothing the final terrain surfaces.
2. The system of claim 1 , wherein the geometric blocks are symmetrical portions of a cube.
3. The system of claim 1 wherein the geometric blocks are wedges or triangles.
4. The system of claim 3 , wherein the geometric blocks are vertical or corner wedges.
5. The system of claim 1 , wherein the geometric blocks are rectangular portions of a cube.
6. The system of claim 1 , wherein the terrain surface comprises ground and grass surfaces.
7. The system of claim 1 , wherein the blocks are stored on a voxel grid.
8. The system of claim 1 , wherein scalar motions with a computing input device are used to build terrain or to remove terrain.
9. The system of claim 1 , wherein physical impact simulations are programmed to destroy specific amounts of terrain creating destruction zones characterized by an impact signature.
10. The system of claim 9 , wherein the impact signature is a crater and the simulation is that of a bomb dropping on the terrain.
11. The system of claim 9 , wherein the impact signature is a tunnel and the simulation is that of a laser beam.
12. The system of claim 1 , wherein terrain features include one or a combination of hills, mountains, cliffs, plateaus, canyons, vertical formations, caves, arches, tunnels, and craters.
13. The system of claim 1 , wherein the Internet-connected server is a game server.
14. The system of claim 1 , further including an interface for building terrain, the interface including at least one slider control for characterizing at least one terrain property.
15. A method, provided by an Internet-connected computerized server, for adding terrain to a virtual world terrain simulation with the aid of a computing appliance having access to the simulation and software executing on the Internet-connected computerized server from a non transitory physical medium, the software performing the steps of:
(a) determining a portion of terrain for modification;
(b) inputting information, the information characterizing at least the amount of terrain to be added.
(c) analyzing the terrain surrounding the terrain portion of step (a) in light of the information provided in step (b);
(d) selecting blocks to add to the terrain based on the analysis of step (c), the selection process including selection of block shape and orientation; and
(e) placing the blocks according to their selection order and orientation.
