The invention provides an access memory method for realizing shear wave data three-dimensional visualization by aiming at parallel volume rendering. According to the access memory method, four-based access memory optimization strategies including texture memory strategies, global memory strategies, global and share memory strategies, constant memory strategies designed by aiming at a visual angle matrix frequently invoking shear wave data, and rendering quality evaluation method and criterion are provided. Through the access memory method, the rendering efficiency for realizing the shear wave data three-dimensional visualization by adopting a volume rendering method on the basis of a CUDA (compute unified device architecture) can be improved. Therefore, the access memory method perfectly helps scientific research personnel to accurately know the plate tectonics, the dynamics process, the earthquake generation mechanism and the like, and further, the fields of geological exploration, continental plates, seismic interpretation and the like are favorably developed.
