中文摘要:随着大气科学相关技术的高速发展,基于软件图形显示功能的更高展示要求在气象行业中被不断提出。人们在持续追求更加逼真视觉上的渲染效果:一方面保证稳定高效地渲染海量数据,另一方面,同时保证高质量图像文件的生成。为此,提出了一种针对海量气象数据的快速显示方案。通过有效压缩传输数据,并利用GPU显卡资源进行数据的渲染和数据的时间插值,能够有效提高数据显示渲染和交互的效率。实践应用表明,该方案能够较好地解决海量数据快速显示的问题,在针对气象大数据进行实时渲染动画播放之时,其播放展示速度可以高达30帧+(每秒),能够较好地满足实际业务需求。 |

Abstract:With the rapid development of atmospheric science and technology, higher display requirements based on software graphic display function are constantly proposed in the meteorological industry. People continue to pursue more realistic visual rendering effect: on the one hand, to ensure stable and efficient rendering of massive data, on the other hand, to ensure the generation of high-quality image files. To solve this problem, a fast display scheme for massive meteorological data is proposed. By effectively compressing and transmitting data, and using GPU graphics card resources for data rendering and data time interpolation, the efficiency of data display, rendering and interaction can be effectively improved. Practical application shows that the scheme can better solve the problem of rapid display of massive data. When the real-time rendering animation for meteorological big data is played, the display speed can be as high as 30 frames + (per second), which can better meet the actual business need. |
