Resampling is that every image element in the screen gives off one ray according to the planned observing orientation. this ray penetrates 3d data sets, and to chooses k sampling dots of equidistance along with it, and does three linear insert values according to color and opacity values of eight data dots that mostly close to certain sampling dot, then evaluate the opacity value and color value of it
重采樣，是從屏幕上的每一個象素根據設定的觀察方向發出一條射線，這條射線穿過三維數據場，沿著這條射線選擇k個等距的采樣點，並由距離某一采樣點最近的8個數據點的顏色值和不透明度值做三次線性插值，求出該采樣點的不透明度值及顏色值。 -
