The invention discloses a shear-warp-based parallel volume rendering system. The system is characterized in that: a distributed parallel visualization system is constructed on the basis of a high-speed shear-warp volume rendering algorithm aiming at the data visualization application requirement of a large-scale data field. Load balance between nodes and rendering speed are further improved by a task division method based on a scanning line and a load balance principle and an adaptive frame rate control strategy based on an army integrated air and missile defense (AIAMD) idea on the premise of guaranteeing quality of a visual image.
