3D fluid scene synthesizing based on video

Abstract

We present an approach for synthesizing larger 3D fluid scene with frame example of video. Both rich realistic texture and height field of fluid particles are employed to study. Realistic textures can enhance the synthesized fluid appearance, whereas the height field enable the generation of complex geometry and stochastic movement on the surface. Our method achieves a good trade off between the visual quality and the production cost. It includes four steps of height field calculating, belt areas clustering according to main components of height field histogram, 3D fluid scene constituting, and transition smoothing both in geometry and appearance. To generate temporally coherent 3D fluid scene over a fluid sequence, we transport fluid video information of colors, height values and particle texture coordinates over fluid sequence. We demonstrate our synthesis results for different scales of larger fluid scenes in several challenging scenarios and provide qualitative evaluation to our method.
