摘　　要：着眼三维虚拟场景装备功能展示及操作使用训练的实际需求,在自主研发的视景仿真软件平台中设计实现了自定义关键帧动画。在自定义关键帧动画中,可以定义虚拟实体的动作组合、第一人称视点变化、烟火、爆炸等特殊效果以及场景光照变化等内容,表现复杂的动态场景。系统实现了自定义关键帧数据"所见即所得"方式的编辑处理,并提供了关键帧数据辅助生成功能,为基于自定义关键帧动画建立各种动态场景提供了支撑。Focusing on the training requirement of equipment operating in 3-D virtual scene,a kind of key frame animation was designed in scene simulation software platform which was developed independently.Movement of virtual entities and camera,changing of lighting,creating of special effects about smog and blast,etc in 3D scene could be defined in the custom key frame animations.WYSIWYG developing environment of the key frame animation was realized,and the function of computer aided generation of key frame animation data was provided,so many kinds of dynamic 3D scene could be built based on it.
