Embodiment Construction

[0015] The following description sets forth exemplary methods, parameters, etc. It should be recognized, however, that the descriptions herein do not limit the scope of the invention, but illustrate exemplary embodiments.

[0016] Using character rigs to model computer-generated characters complicates support for computer animation systems. Viewers of computer animation typically expect computer-generated characters to move in unison with connected body parts. To achieve this effect, when a computer animation system determines the motion of one part of the computer-generated character, it must take into account the influence of other parts of the computer-generated character on the specific motion being modeled. The movement of one part of the character skeleton may be restricted by other parts.

Abstract

Orbital manipulators indicate one or several ranges of motion for a part of a computer-generated character in a computer animation system. The orbital manipulator takes a computer-generated character model. The model may be an articulated skeletal structure, where interconnected bones may restrict each other's motion. When the artist chooses to move one of the bones, the orbit manipulator determines the range of motion for the selected bone. This decision can be based on the position and / or range of motion of other bones in the skeleton. The range of motion is displayed on-screen to the artist along with the computer-generated character. In this way, the orbital manipulator directly informs the artist of the range of motion that the artist can move for the selected parts of the computer-generated character.

Description

technical field [0001] The present invention relates generally to computer graphics and, more particularly, to tools for rigging computer-generated characters in computer animation. Background technique [0002] In computer animation, a computer-generated character can be modeled by a character skeleton. Typically, a character skeleton defines the different parts of a computer-generated character, as well as their respective characteristics. For example, some parts of a computer-generated character may be flexible while other parts are rigid. In addition, compared with the various parts, some parts may have more freedom of movement, while others may be restricted. The computer-generated skin layer overlays the character skeleton to give the computer-generated character the desired visual appearance, which may include, clothing, skin, hair, etc. The movement of the character skeleton between successive animation frames causes the corresponding deformation of the skin layer...
