For these applications, artists are often requested to achieve the desired visual appearance by adjusting some parameters for rendering them. However, this is extremely difficult and tedious, due to the complexity of these phenomena and the expensive computational cost for the rendering. This paper presents an interactive system that assists this adjustment process. Our method allows the user to interactively change the ratio of smoke and flame regions, the emissivity of the flame, and the optical thicknesses of the smoke and flame separately. The image is updated in real-time while the user modifies these parameters, taking into account the multiple scattering of light. We demonstrate the usefulness of our method by applying our method to editing of the visual appearances of fire and explosionsI.3.7 [Computer Graphics]Three Dimensional Graphics and RealismVolume Rendering10.2312/egsh.2015101249-52
