Abstract

Computer-simulated three-dimensional environments include automatable and/or constrainable camera control, for video gameplay, real estate and/or landscape demonstrations, or any other digitizable environment. In gameplay applications, the system can be customizably programmed to automatically adapt to the environment based on the player'"'"'s location within the virtual environment, information about what the programmer believes is relevant (or wants to make relevant) in the scene being displayed, and other factors. Certain embodiments of the inventive apparatus and methods generally automatically incorporate and honor the “rules of cinematography,” but also preferably include other “action video game” principles that can override or trump those rules.

Claims

1. A computer system for facilitating human interaction in a virtual environment, the system comprising:

an algorithm-driven camera system, programmed to operate in a fast paced dynamic environment without modifying the state of the objects in that environment, said system using the human'"'"'s input of movements and actions within the virtual environment to determine and frame a camera view for display to the human, without any need for separate input from the human to operate the camera.

2. The system of claim 1, in which at least one algorithm takes into account cinematographic or other “

rules”

that can be created and/or selected by a programmer, and then automatically controls the camera view experienced by the human according to said rules.

3. The system of claim 1, in which at least one algorithm takes into account cinematographic or other “

rules”

that can be created and/or selected by the human, and then automatically controls the camera view experienced by the human according to said rules.

4. The system of claim 1 or claim 2 or claim 3, in which the system includes a human-controlled main character, and at least one algorithm takes into account and analyzes relevant information in the virtual scene such as the position of the human-controlled main character, the position of other characters in the scene, environmental features, various special effects, and the occurrence of special events during the human'"'"'s use of the system.

5. Apparatus for providing interaction between one or more humans and a 3D virtual environment, including:

a 3D virtual environment, said environment including a plurality of points of interest that are preselected and weighted in importance by a programmer;

at least one main character within the environment;

a display device for displaying the environment to said one or more humans;

a control device by which said one or more humans can control said character, including moving said character within the environment;

a plurality of cameras that are programmed to travel with the main character as that character moves within the environment; and

a modifier stack module, said module including the ability to automatically select from among said cameras the one that will be displayed on said display device to said one or more humans.

6. The apparatus of claim 5, in which said modifier stack module uses said plurality of weighted points of interest in the automatic camera selection process.

7. The apparatus of claim 5, including a dampening module to smooth transitions in the virtual camera movement displayed to said one or more humans.

8. The apparatus of claim 5, including means for dampening the virtual camera movement displayed to said one or more humans.

9. The apparatus of claim 5 or claim 6, in which said dampening involves an iterative algorithm using at least three points within said virtual environment.

10. A method for selecting a camera view within a virtual 3D environment, including:

providing a virtual 3D environment having programmed therein points of interest (POIs) identified as having relative degrees of importance;

providing a plurality of camera views into that virtual world;

using said relative degrees of importance of said POIs to select from those camera views the camera view to be displayed to a human interacting with the virtual environment, without requiring human control of said camera view.

11. A computer-readable storage medium having stored therein instructions capable of causing a computer to perform the method of claim 10.

12. A method for controlling the simulated movement of a camera through a virtual 3D environment, including:

providing means for determining an ideal viewpoint to display from the virtual environment;

providing means for determining the camera viewpoint current being displayed;

providing means for smoothly transitioning the viewpoint being displayed from the current viewpoint toward the ideal viewpoint.

13. The method of claim 12, including using a dampening algorithm to help accomplish the step of smoothly transitioning the camera viewpoint.

14. A computer-readable storage medium having stored therein instructions capable of causing a computer to perform the method of claim 12.

15. A computer-readable storage medium having stored therein instructions capable of causing a computer to perform the method of claim 13.
