New in version preview.2009-Oct-23 (October 24th, 2009)

  • new input parameters enhance screenshot from the command line:
  • mindens : set minimum density threshold
  • maxdens : set maximum density threshold
  • com : boolean to center according to the center of mass
  • cmapindex : give the colormap index
  • colormap can be selected directly from the user interface
  • experimental temperature display
  • bugs fixed

New in version preview.2009-Jul-16 (July 17th, 2009)

  • Glnemo2 gets accelerated !!!
  • huge speed up on the rendering engine (up to 1000% !), thanks to :
  • vertex buffer object
  • vertex and pixel shader (via glsl)
  • density rendering engine, to display and color particles according to their
  • density and the distance of their Kth neighbours. It works with gadget2
  • snapshots with gas components, and with NEMO snapshots with density field.
  • offscreen rendering, using frame buffer object, to take screenshot from the command line and from the GUI
  • new input file format phiGRAPE
  • possibility to record and display orbits
  • list of files does not need header anymore
  • camera path using b-splines, to fly over the simulation
  • **TONS** of bugs fixed
