3D fluid scene synthesis and animation

Realistic fluid scene modeling is necessary for virtual reality application. Large 3D fluid scene modeling in low performance computer with real time remains a challenge. Here we present an approach for synthesizing large 3D fluid scene with example of frame in video. Both rich of realistic texture in video frame and height field of fluid surface are employed to study. Realistic textures can enhance the synthesized fluid appearance, whereas the height field of fluid surface enables the generation of complex geometry and stochastic movement on the surface. We take advantage of fluid wave theory to study and extract wave elements from fluid surface of example frame. The extracted wave elements are clustered and rearranged into the synthesized result. MST (Minimum Spanning Tree) of wave element classes is constituted to keep local continuity to fluid surface. We demonstrate our synthesis results for different scales and different types of large 3D fluid scenes synthesis in several challenging scenarios.
