SDvision display of HERACLES simulations of ISM turbulences on a slice.
SDvision display of RAMSES simulations SDvision display of HERACLES simulations of ISM turbulences.
The SDvision widget used to visualize a surface of the density distribution in the Interstellar Medium obtained in an HERACLES simulation. The navigation capabilities of the widget make it possible to rotate, displace and scale the scene at will through mouse actions. The distribution is also projected onto an image on which profiles can be interactively obtained. Menus are used to modify the attributes of the objects on display (palette, shading, texture, lighting). Sliders can be used to scan through the volume in either direction.
The SDvision widget provides simultaneous access to the N-body data and the complex AMR octree structures generated by RAMSES. In the example above, the 128´128´128 Dark Matter particles are viewed together with an image of the hydrodynamical baryon density. An histogram of either the DM density or velocity is displayed, used to select a subset of the full particle complement. On the left-hand side, an interface is dedicated to loading data and select higher resolution levels. The highest resolution is reached at level 14 of the AMR, equivalent to that of a 8192×8192×8192 Cartesian grid and 4.1×10E7 cells . The AMR data are projected onto regular Cartesian grids. The SDvision widget allows to visualize complex, composite scenes. The graphical objects lifecycles are managed through the use of controllers (displayed on the right hand side). Such controllers are implemented for « data objects » (isosurface, volume projection, image, vectors, streamlines), « geometry objects » (boundaries, axis), and « scene objects » (illuminations). Objects are configured through dedicated interfaces. In the example above, obtained in a 200´200´200 regular-grid HERACLES simulation, the scene includes two isosurfaces, one image and one streamline objects. Isosurfaces are 3D contours. An histogram of the associated data is displayed and can be used to set interactively the desired contour value.
