Previous Work: Previous Work Stochastic Motion Textures [Chuang et al. 05] Image-based rendering [Chen et al. 95, Gortler et al. 96, Kang and Shin 04, Hoiem et al. 05] Extension of TIP [Kang et al. 01] Tour Into the Picture [Horry et al. 97]Overview: Overview a still picture an animation 3D Scene Construction: 3D Scene ConstructionEstimation of Scene Parameters: Estimation of Scene ParametersConstrained optimization problem: Constrained optimization problem user-provided m pairsThree Types of Maps: Three Types of Maps Texture map Mask map Reflection Map 3D Scene DecorationReflection Map: Reflection Map Pixel by pixel correspondence Stochastic motion texture for passive objects: Stochastic motion texture for passive objects Animating Pictures with Stochastic Motion Textures [Chuang et al. SIGGRAPH 05] Motion GenerationSlide12: Water Surface Movement approximated objects Interaction with objects such as ground, rocks, and boats geometry of water surface and interacting objects RealFlowSlide13: Rendering For each pixel, one ray is shot Intersection check order Foreground (lower depth => higher depth) Background, Ground plane Water plane : reflection map Foreground background image ground water camera RaytracingExperimental Results: Experimental Results Intel Pentium PC P4 3.0 GHz, 2.0 GB RAM, GeForce FX 5950 More than 10 frames/secConclusions: Conclusions Generalization of TIP with water surface reflection and object movements - semi-automatic 3D scene modeling - water surface reflection You do not have the permission to view this presentation.
