Mobile device-oriented multi-point touch gesture interaction three-dimensional modeling method

Abstract

The invention discloses a mobile device-oriented multi-point touch gesture interaction three-dimensional modeling method. The method mainly comprises the steps of initializing a three-dimensional modeling space; defining a three-dimensional modeling operation function set in the three-dimensional modeling method, wherein the function set comprises generation, control and editing function operation subsets, and multi-point touch gesture behavior subsets corresponding to function operations; performing single-finger or multi-finger gesture interaction operation and monitoring on a touch screen supporting multi-point touch; and identifying gesture operations, mapping identified gesture operation behaviors to a three-dimensional modeling function and performing calling. According to the method, the corresponding three-dimensional modeling operation can be performed on a mobile device by combining multi-point touch gestures, so that the shortcomings of finite screen space and inaccurate clicking of the mobile device are overcome; the method has the advantages of quickness in modeling, low learning cost and intuitiveness in use; and a three-dimensional modeling system solution suitable for a mobile platform is given.

Description
