VITESS 3.0  Release Note
------------------------

Visualization:
--------------
A framework for the visualization of the instrument geometry and neutron trajectories
has been implemented. Modules produce individual output files in special exececution
modes which are gathered in another step and transformed to X3D (3 dimensional virtual reality)
or SVG (2D vector graphic) files then, under control of the GUI.
Virtual reality scenes may be examined with external viewers then, as 2D graphics
may be shown by means of a browser.
The framework has been filled for the following modules yet:
Source, guide, chopper_disk, space, spacewindow, slit, supermirror ensemble, guide_elliptic and detector
and is considered "beta".

Pipe import:
------------
Simulation pipes with VITESS modules may be (re-)imported to a GUI representation
of the instrument, the input file may be any text file with a line containing 
the pipe command.

The maximal number of modules in the pipe has been extended to 100 now.

New modules:
------------
elliptic guide: Represents a guide with a true elliptic shape, opposed to the regular guide module, which approximates a curved shape by segmentation and interpolation.
mon_brilliance: Displays the brilliance distribution
monitor1D     : A generic 1D monitor

Source characteristics:
----------------------
- FRM-2 included as source
- New ESS cold source
- New HZB cold and bi-spectral source

Bug fixes, improvements:
-----------------------
- monitor1D & 2D  : Color as filter variable introduced
- monochr_analyzer: Transition mode added
- sample_reflectom: Incoherent scattering added
- monitor1        : option to writeout files for colour 0, 1, 2, ... simultaneously (max. 10)
- eval_inelast    : calculation of energy transfer and restriction of ang. range corrected
- guide           : counts reflections separately in hor. and vert. direction
- sm_ensemble     : counts also reflections
- ...
