The traditional algorithm of volume rendering is ray - casting, not a proper algorithm for the large 3 - d seismic data, referring some improved method and considering the characteristic of seismic data, a new fast ray - casting algorithm of oriented image space and negative - view transform was brought forward. as a result, this algorithm excels the traditional obviously by speed with image quality in experiment
體繪制的傳統演算法是光線投射法，由於地震數據量大而繪制速度太慢，本文在借鑒一些改進演算法的基礎上，結合地震數據的特點，提出了一種基於圖像空間的逆視變換的加速光線投射演算法，實驗結果表明該演算法在保證相同圖像效果的同時，具有明顯的速度優勢。 -
