A 3D image animation engine

Abstract

The invention provides a 3D (Three-Dimensional) graphic animation engine. The 3D graphic animation engine comprises a 3D graphic processing module and an OpenGL (Open Graphics Library) bottom layer, wherein the 3D graphic processing module can provide a large amount of geometric calculations and is used for establishing and leading in various meshing models, and the OpenGL bottom layer is used for realizing the drawing and the rendering of a graph; the 3D graphic processing module and the OpenGL bottom layer are encapsulated; the 3D graphic processing module comprises a view, a module and an iterator; the view is an interface which is used for connecting the module and the iterator; the module comprises a public data area, a data interface and a graph drawing interface, the public data area is used for storing public data of the module, the data interface is used for providing a method for a mobile phone operation system and / or a parent module of the module to modify the public data in the public data area, and the graph drawing interface is used for realizing module drawing by the mobile phone operation system during a drawing thread according to the public data of the public data area. The 3D graphic animation engine provided by the invention is suitable for mobile phone operation systems and can be used for effectively and smoothly displaying all kinds of two-dimensional or three-dimensional graphic animations.

Description

technical field [0001] The invention relates to a drawing device and method suitable for displaying various two-dimensional or three-dimensional image animations and graphic effects on a mobile phone operating system, specifically, a 3D image animation engine using OpenGL bottom layer rendering. Background technique [0002] Mobile phone operating systems are mainly used on smart phones, and mainstream smart phones include Android and Apple's iOS. [0003] At present, the display of images or animations on the mobile phone operating platform is based on the UI engine display that comes with the mobile phone platform, but the UI engine that comes with the mobile phone operating system is over-encapsulated, and its animations and views are in one-to-one correspondence. In the case of too much, the memory overhead occupied by the animation and the engine-driven calculation overhead increase, which reduces the speed of displaying images or animations. Moreover, the built-in UI ...

[0003] At present, the display of images or animations on the mobile phone operating platform is based on the UI engine display that comes with the mobile phone platform, but the UI engine that comes with the mobile phone operating system is over-encapsulated, and its animations and views are in one-to-one correspondence. In the case of too many, the memory overhead occupied by animation and the overhead of engine-driven calculation increase, which reduces the speed of displaying images or animations

Moreover, the built-in UI engine of the system can only display simple two-dimensional animations with a small number of simultaneous running per unit time, let alone display three-dimensional animations. In addition, the components of the built-in UI engine are more complicated, which increases the number of developers. Difficulty with custom components
