ChangeLog 3

Back

[02/03/94] RS pixutils.c
Improved the efficiency of the RasMol polygon rendering.
[02/03/94] RS command.c tokens.h
Added the "colour trace" command (and the "trace" command)
to make "trace" synonymous with the "backbone" command.
[01/03/94] RS abstree.c abstree.h command.c tokens.h
Added the rasmol "define" command to allow sets to be
defined by the user.
[01/03/94] RS command.c tokens.h
Added the RasMol "echo" command.
[28/02/94] RS outfile.c
Improved the implementation of "write vectps" to correctly
handle wireframe intersections with spheres and to draw
cylinder bonds to produce effective ball & stick pictures.
[22/02/94] RS command.c render.c transfor.c
Added nucleic acid ribbon representations. By default, a
nucleic acid ribbon is 720 RasMol units wide. The O5* atom
defines the RNA ribbon plane, and the midpoint between O5*
and O2P defines the DNA ribbon plane.
[21/02/94] RS command.c tokens.h render.h
Added RasMol commands "set axes", "set boundbox" and "set
unitcell" to display additional objects.
[17/02/94] RS transfor.c transfor.h
Added the RasMol command "colour structure" to colour proteins
by secondary structure type. Removed the "user" colour option
from the UNIX menu system and replaced with "structure".
[16/02/94] RS command.c transfor.c
Changed the semantics of "ribbons 0" and the RasMol "ribbons"
menu option to display ribbons whose width varies by secondary
structure type.
[15/02/94] RS rasmol.c raswin.rc
Changed the menu item "Save" to "Export" which makes more
sense for generating image files.
[14/02/94] RS raswin.c x11win.c graphics.h command.c tokens.h
Added the "set mouse" command to RasMol to allow the RasMol
mouse bindings to emulate other packages. RasMol currently
supports "set mouse insight" and "set mouse quanta".
[13/02/94] RS rasmol.1 rasmol.hlp rasmol.html raswin.hlp
Completed work on the RasMol "on-line" help preparation
system. Now the UNIX man pages, Microsoft Windows help,
Mosaic HTML and RasMol/RasWin online help is prepared from
the same source. All these files are now up to date.
[10/02/94] RS command.c tokens.h molecule.c molecule.h
Added the rasmol "show symmetry" command.
[27/01/94] RS rasmol.c
Improved command line editting under VAX VMS. Fixed VMS bug
that caused the process to "crash" after RasMolExit().
[26/01/94] RS rasmol.c
Extended VAX VMS port of RasMol using ASTs to allow the
asynchronous receipt of characters from SYS$INPUT:
[26/01/94] RS graphics.h command.c
Allow the command line state (prompt) to enable/disable
the menu buttons, this solves a GUI style flaw/bug.
[07/01/94] RS molecule.c transfor.c
Corrected potential bugs when detailing with upper and lower
bounds on Main and Heta residue numbers and temperatures.
[07/01/94] RS x11win.c
Made the second and third mouse buttons synonymous.
[07/01/94] RS molecule.c molecule.h command.c tokens.h
Added the RasMol "renumber" command to ensure sequential
residue numbering alongs macromolecular chains.
[07/01/94] RS transfor.c transfor.h command.c tokens.h
Added the RasMol "centre" command to allow rotation of a
molecule about the centre of gravity of a given set of atoms.
[06/01/94] RS x11win.c
Solved colourmap problem on Silicon Graphics machines that
caused some colours to be displayed incorrectly!
[06/01/94] RS abstree.c
Corrected bug in ParsePrimitiveExpression that caused general
wildcards (i.e. "*" and "*.*") to be treated incorrectly.
[05/01/94] RS x11win.c
Renamed the variable "shminfo" to avoid a name clash when
compiling on the DEC Alpha using OSF/1 and Ultrix. Thanks
to Dan Jacobson.
[04/01/94] RS !Started visiting research post with the
Protein Biochemistry group at Glaxo Group Research,
Greenford, Middlesex.
