The program consists of a main window and an additional sidebar for entity-selection.
Because DINO is still in its early stages, the GUI isn´t very sophisticated and most of the interaction has to be done via the terminal Dino is being run from.
The graphics are handled by OpenGL, so it looks good but is quite slow (as usual) if you don´t own an SGI or a new hardware-accelerated Linux-box.
The most annoying glitch is, that I can´t edit the command line (but this might be a bug or wrong configuration of my SuSE-Linux-setup), which would be very helpful. There is a history function but no editing or auto completion.
Despite this , Dino seems to be quite stable and the graphics look quite good.
It is the only program, which can explicitly read in data from AFM-microscopes (if you need that)

DINO is a real time 3D visualization program running under the X-windows system and using the powerful OpenGL library.
There are five data-types supported: structure (atomic coordinates and trajectories), surface (molecular surfaces), scalar fields (electron densities and electrostatic potentials), topographs (surface topography scans) and geom (geometric primitives such as lines).
Supported input file formats are PDB (coordinates), X-PLOR/CNS (coordinates and electron densities), CHARMM (coordinates and trajectories), CCP4 (electron densities), UHBD (electrostatic potentials), DELPHI/GRASP (electrostatic potentials), MSMS (surfaces), MSP (surfaces), MEAD (coordinates and electrostatic potentials) and greyscale TIFF (surface topographs).
Output can be written as TIFF, RGB, Postscript, Raster3D or POV-ray.
