【摘要】 随着消费类电子的应用和普及，嵌入式图形界面的设计将直接决定用户的体验效果，三维控件作为未来立体图形界面的重要组成部分，具有非常大的潜在价值。选择Android系统作为三维控件开发平台，不仅是因为它具有强大的功能支持，开源的应用许可，而且还考虑到Android系统三维控件的发展现状以及当前的市场需求。通过分析Android图形系统提出三维控件整体设计架构。以Android自带二维控件为基础，概述控件的开发原理及应用需求，并通过比较得出三维控件在功能和性能上的特殊需求。基于Android图形的三维控件的整体设计包括jMonkey的移植、三维场景的实现、三维控件集的设计三个部分。JME的移植主要是根据图形引擎的特性设计其在Android平台上的接口，包括系统接口和应用程序接口两个部分。利用JME移植接口可以创建基于OpenGLES的三维场景，根据场景实现原理，分析并完成场景内节点的设计以及控件模型的创建与加载。重点分析三维控件集各组成部分的实现原理。控件的外观属性配置是控件最明显的可视属性，包括二维控件的外观映射属性、控件在三维场景中的材质属性两部分；控件的动画制作解析是控件交互不可或缺的组成部分，关键帧动画不仅能够提供丰富的动画的资源，而且其动画效果较其他动画类型流畅。它通过第三方软件制作，采用解析类中的方法绑定到jMonkey三维控件模型，响应系统中动画事件；纹理映射完成了Android控件外观与jMonkey节点模型纹理的绑定，通过映射把Android中二维控件绘制的Bitmap以Texture的方式加载到三维控件模型上，实现二维控件到三维场景节点的映射；三维控件的事件交互是设计的重点，分别从线程间事件消息的传递和事件消息的捕获、分发、处理几个方面，详细论述三维控件如何通过监听和回调机制实现事件消息的响应。更多还原

【Abstract】 Along with the application and popularization of consumer electronics, the design ofembedded graphical user interface will directly determine the user experience effect,three-demensional control as an important part if future3D graphical interface, has greatepotential value. Choose Android system as the three-dementional control developmentplatform, not only because it has powerful support, application permission to open source,but also take into account the development status of3D Android control system and thecurrent market demand.Through the analysis of the Android graphics system puts forward the wholearchitecture of the three-dimensional controls. Base on the Android two-dimensionalcontrol, providing an overview of the development principle and application demand ofcontrol, through the comparison to draw three-dimensional control special requirements onthe functionality and performance.Overall design that based in Android graphics includesjMonkey transplants, the realization of the3D scene, the three domensional control setdesign three parts.The transplantation of JME is mainly based on the characteristics of the graphicsengine to design the interface in the Android platform, which including two parts of thesystem interface and application program interface. Based on OpenGL ES using the JMEtransfer interface to create a3D scene, according to the implementation principle of thescene, analysis and complete the scene node design and the creating and loading of thecontrol.Focus on analysis of the implement principle of each component ofthree-dimensional controls. The appearance of attribute configuration control is the mostobvious in visual attributes, it contains the appearance of mapping attribute and thematerial properities in the3D scene.The animation of3D control is a part of an analyticalcontrol interaction, key frame animation can not only provide rich animation resources, butits animation effects is more smoother than any other types, it is made by third partysoftware, using the analytical method in the class to bound to the jMonkey control modelin the3D scene, and respond to the system animation event. Texture mapping is completedby the Android appearance of the2D control and the texture of the jMonkey model binding,with mapping the Android2D control in Bitmap in the form of Texture loaded into the3D control model.3D control event interaction is the focus of the design, separately from twoaspects of the event messages between threads and event capture, processing, distributionto discusses in detail how to respond the event by the methods of monitoring andcallback mechanism to realize the event message.更多还原
