A Geometric Control of Fire Motion Editing
Xiaobing Feng, Dengming Zhu, Zhaoqi Wang · 2015
In this paper, we present a control technique to editing the fire motion with the geometry goal shape, which is designed without connection to physical parameters and physical equation solving. To fulfill this, controlling elements are extracted from the input curves conveying the target shape of fire animation. Then a force field is obtained according to these controlling elements, which would drive the fire towards the target shape. Moreover, to optimize the particles' position, a geometric topology model is proposed to maintain the visual details while generating the fire motion under the external force field frame by frame. Experimental results show that our method can generate desirable fire shape under simple interaction.
