Due to the dimension of 8K image, the remote micro and macro images are considered appropriate for visualization with scientific and educational purposes. This article describes the implementation of the 8K video plug-in to play UHD videos into the SAGE, a collaborative environment for the advancement of scientific research and education developed by EVL (Electronic Visualization Laboratory), upgrading its current resolution for video playing. It also presents the challenges of producing 8K content, the development of the code and introduces the features to view 8K ultra high definition videos in multiple tiles through the use of low cost computer clusters. The SAGE 8K video plug-in implementation was made possible because of the previous development of the Fogo Player, a system to run 4K and 8K content. The results were successfully presented at the CineGrid International Workshop 2013 in San Diego.展开更多
