摘　　要：传统显示设备难以满足大规模复杂数据可视化结果显示的需求,而VR多投影环幕显示设备提供的沉浸式显示环境可以良好地应对复杂数据可视化显示的使用情景。提出一种面向VR多投影环幕设备的可视化结果显示方法,通过设计多投影环境中兼容2D与3D显示的渲染流程,解决了传统方法中出现的画面渲染模糊问题。同时,该方法通过3D运动模拟计算以及交互射线计算解决了在新渲染流程下的立体显示和交互坐标转换问题。实验结果表明,该方法有效地提高了多投影环境中可视化结果画面的清晰度,并支持立体显示与交互。Traditional display devices are difficult to meet the needs of complex data visualization.The VR multi-projector cylinder screen device is suitable for complex data visualization by providing immersive experience.This paper proposes a visualization result display method for VR multi-projector cylinder screen device.It solved the image blur in traditional methods by designing a 2D-3D compatible display render process in multi-projector environment.In addition,it solved the problem of stereo display and interaction coordinate transforming by 3D movement simulation and interaction ray calculation.The experimental results show that our method can effectively improve the sharpness of visualization result image in multi-projector environment,and supports stereo display and user interaction.
