摘　　要：从火焰和水波的视频出发,首先进行时间和空间连续性的拼接,利用光流场计算视频帧之间的相似度,通过相似度矩阵计算实现连续小跳变的火焰合成,采用基于骨架的驱动来实现风力与火的交互,实现了火焰的蔓延和互动等效果;采用一种自适应边界采样方法来实现水面的视频合成,得到了较好的模拟效果。Based on video synthesis technique, the authors proposed an approach for the real-time simulation of flowing water and fire video. From the fire and flow video, the continuity of time and space was implemented by the optical flow field method. The interaction between wind and fire was achieved through the skeleton of fire, including the fire spread and interaction of fire flame. The flow was also synthesized by a method of self-adaptive edge sampling. Finally, by the techniques of 3-dimension simulation with videos from multiple directions, good simulation results were achieved.
