A New Volume Rendering Algorithm of Data Field
Xiaofeng Feng, Xiong Shi, Jun Chen · 2010
Through constructing an average opacity buffer with the same size of opacity buffer, the visibility of data cell could be estimated by the value of gravity center of this data cell in average opacity buffer. That could make the data cell which completely located in the average opacity buffer cut during the process of volume rendering in object space sequenced irregular data field and could dramatically reduce the data volume and accelerate the rendering process.
