Animation processing of linked object parts

摘要

The invention relates to a method and system of forming an animation of a virtual object within a virtual environment, and a storage medium storing a computer program for carrying out such a method. The virtual object comprises a plurality of object parts, and one or more predetermined object part groups each being a sequence of linked object parts. The method includes generating a target configuration for the parts of the object part group, using a scale factor to scale the target configuration.

1. A method for forming an animation of a virtual object within a virtual environment, the virtual object comprising a plurality of object parts, there being one or more predetermined object part groups, each object part group being a sequence of linked object parts of an animated limb, the virtual object having, in respect of one or more properties for the virtual object, a respective scale factor specifying a value of a property for the virtual object relative to a reference value for the property, the method comprising, for each object part group of the one or more predetermined object part groups:
providing a first set of one or more parameters including a user input from a user input interface, relating to a next step of the animation, to a predetermined function, wherein a particular object part from the object part group is flagged according to a collision flag denoting whether the particular object part passes through other objects or collides with other objects; the predetermined function determining, based on the first set of one or more parameters including the user input from the user input interface, a configuration for one or more object parts of the object part group; generating a time factor specifying a value of a time taken for the virtual object to fall from a height of the virtual object under influence of a predetermined acceleration relative to a reference time taken for a reference object to fall from a height of the reference object; and generating a target configuration based on utilizing one or more scale factors including the generated time factor, the scale factors being used to scale the one or more object parts to the target configuration according to values of the one or more properties for the virtual object including the generated time factor.
