In the thesis a volume rendering algorithm is put forward using shear - warp factorization of the viewing transformation and two - pass classification, it utilizes the coherence of volume data, classifies the data for the first pass and encodes the volume data using a run encoding, the encoded data is classified for the second pass when it is rendered. using the feature for two pass classification, it uses octree data structure speed up the rendering, realizes a very good volume rendering algorithm
本文提出了兩次分類錯切變形體繪制演算法，該演算法充分發掘體數據的一致性，首先對數據進行第一次分類，對第一次分類的結果進行行程編碼，實現了數據的壓縮，對壓縮的體數據進行第二次分類繪制；同時依據兩次分類的特點，利用八叉樹進行加速，實現了有效的體繪制演算法。 -
It operates by factoring a projection to form an intermediate. therefor it can run better. this paper deeply investigates the shear - warp algorithm. but two factors caused the distortion of the final image in this algorithm
本文對這一演算法進行了深入的研究，並針對shear - warp演算法產生圖像失真的兩種原因，提出了一種改進方法。 -
This method got the final image by computing two different groups of resample points and projecting them. the first group of resample points is computed in the way just like the ray - casting method. and the second are gotten like the ones getting by shear - warp algorithm, so the new method can run better and rather fast
該方法是通過兩步求取采樣點來合成最終圖像，即先按光線投射的辦法求出一部分正確的采樣點，然後按shear - warp演算法求剩下的采樣點，這樣既提高了最終圖像的質量，又確保了演算法的運行速度。
