We present a flexible interactive 3D morpho-kinematical modeling application for astrophysics. Compared to other systems, our application reduces the restrictions on the physical assumptions, data type, and amount that is required for a reconstruction of an object's morphology. It is one of the first publicly available tools to apply interactive graphics to… (More)
Interactive visualization and simulation of astrophysical phenomena help astronomers and enable digital planetariums and television documentaries to take their spectators on a journey into deep space to explore the astronomical wonders of our universe in 3D.
Poster 5007 Example images of astrophysical nebulae generated in Shape.
We present a powerful new tool to analyse and disentangle the 3-D geometry and kinematic structure of gaseous nebulae. The method consists in combining commercially available digital animation software to simulate the 3-D structure and expansion pattern of the nebula with a dedicated, purpose built rendering software that produces the final images and long… (More)
Based on axi-symmetric hydrodynamical simulations and 3D reconstructions with Shape, we investigate the kinematic signatures of deviations from homologous (" Hubble-type ") outflows in some typical shapes of planetary nebulae. We find that, in most situations considered in our simulations, the deviations from a Hubble-type flow are significant and… (More)
Distant astrophysical objects like planetary nebulae can normally only be observed from a single point of view, which makes deducing plausible 3D models a hard task that usually involves a lot of manual work [Nadeau et al. 2001]. However, additional physical assumptions can be used in order to estimate the missing depth information. In previous work [Wenger… (More)
— Interactive visualization and simulation of astrophysical phenomena enable digital planetariums and television documentaries to take their spectators on a journey into deep space and explore the astronomical wonders of our universe in 3D. When thinking about astronomical objects, the first thing that comes to mind is probably stars. Interstellar space,… (More)
