A motion picture presents a continues phenomena as a sequence of frames. We perceive continuity by "filling in the gaps" and "smoothing out " the missing information. While faster motion requires more frames during a given time period, there is a point where more frames per second yield no further improvement. The "sampling speed" must be fast enough to allow "appropriate averaging of dead times between frames", but need not accommodate motion too fast to be seen by a human. The above description is somewhat analogous to sampling of audio signals. The sampling rate depends on how fast the signals vary (the highest frequency we hear). Nyquist showed that sampling frequency exceeding twice the audio bandwidth is sufficient to include all the signal information, preserving the finest details up to half the sampling rate

平截头圆锥体划分为三个辐射面—火焰侧面、火焰顶面及火焰底面。基于微元思想进一步对喷射火辐射表面进行了合理的离散化，对喷射火平截头圆锥体的视角因子进行研究。 (To simplify the view factor calculation process, the cone frustum with a certain angle is transformed into the vertical cone frustum and the transform parameter formulas are achieved.)
