[05/05/95] RS render.c
Corrected 16bit precision problem with cartoons on PCs and
Macintoshes. These caused rounding errors in `ribbons'.
[02/05/95] RS INSTALL
Added additional build info for RasMac on the PowerPC using
Metrowerks C++ v1.2. This requires additional files to v1.1.
Special thanks to Graham Palmer.
[03/04/95] RS pixutils.c pixutils.h render.c command.c
Added the ability to display dashed "strands" ribbons.
[03/04/95] RS render.c
Modified the handling of the first and last residue in
a chain to only extend to the alpha carbon except when
the last residue is an arrow head.
[27/03/95] RS render.c
Fixed bug in cartoon representation when final residue in a
chain is a beta-sheet. Improved "CalculateInten" performance.
[27/03/95] RS rasmol.c
Made several changes to rasmol.c to allow RasMol to compile
with DEC C (on AXP and VAX) without /standard=vaxc. Special
thanks to Martin Zinser.
[26/03/95] RS render.c render.h pixutils.c pixutils.h command.c
tokens.h
Added the new representation "cartoon" which represents a
protein as a Richardson-style cartoon. The width of the
cartoon is given as a parameter, the depth of the ribbon
and use of arrow heads may be changed using "set cartoon".
[25/03/95] RS render.c command.c transfor.c molecule.h
Changed the semantics of the "trace" command and added a
new representation, "trace" which displays a cylindrical
spline representation of "backbone".
[22/03/95] RS render.c render.h command.c tokens.h transfor.c
script.c
Added the "Monitor" representation to RasMol as an dashed
line between two atoms, optionally labelled by the distance
between the atoms (the default).
[16/03/95] Makefile
Added comments about use of +O4 optimisation using HPUX 9.05
on the native PA-RISC compiler. Thanks to Richard Mathar.
[13/03/95] RS outfile.c
Implemented dashed lines in RasMol's vector PostScript output.
This now includes the ability output of hbonds and ssbonds.
[13/03/95] RS script.c
Fixed bug when generating RasMol scripts caused by overlapping
datum type masks. This caused errors with dashed vectors.
[12/03/95] RS x11win.c
Fixed a problem using scroll bar arrows to spin a molecule
with three-button emulation on XFree (Linux and NetBSD).
[07/03/95] RS render.c
Improved performance of "isqrt" routine, the most frequently
called function when rendering ribbons.
[06/03/95] RS render.c
Implemented the routine "InitialiseTables" to avoid using
"isqrt". This drastically reduces the start-up time.
[06/03/95] RS render.c
Improved rendering of double & triple bonds.
[03/03/95] RS command.c render.c render.h pixutils.c
Added the ability to display double and triple bonds as
two and three lines using the "set bonds true" command.
[03/03/95] RS command.c tokens.h render.c transfor.c script.c
rasmol.c
Added the ability to display bonds and backbones as dashed
lines using either the "dashes" command or the "dashes"
parameter to the "wireframe" and "backbone" commands.
[03/03/95] RS command.c
Modified 'FetchFile' to display explicitly specified
hydrogen bonds by default.
[03/03/95] RS pixutils.c
Improved quality of dashed lines.
[02/03/95] RS render.c molecule.c transfor.c transfor.h
Ported RasMol to compile under Borland's Turbo C/C++. This
required rewrite of ClearBuffers to avoid "_fmemset" bug.

Tidied up many of the image file output routines.
[28/02/95] RS molecule.h abstree.c abstree.h
Improved handling of RNA bases and conversion of non-standard
nucleotide atom names. Thanks to Hans Hoppe.
[17/02/95] RS molecule.c
Finally implemented internal to cartesian co-ordinate
conversion for MOPAC internal input files. Very special
thanks to Klaus-Peter Gulden.
[16/02/95] RS molecule.c
Added detection of MOPAC file types, and added support
for MOPAC cartesian co-ordinate input files.
[15/02/95] RS molecule.c
Added support for reading MOPAC output files including
charge information (provided the job doesn't use the
"NOXYZ" keyword as an option).
[14/02/95] RS render.c
Added "X", "Y" and "Z" axes labels to the "set axes on"
command.
[13/02/95] RS render.c render.h command.c

Improved performance of function DisplayString avoiding
clipping and reduced intensity of atom labels.
[09/02/95] RS abstree.c
Implemented function 'CalcTorsion' for "set picking torsion".
[06/02/95] RS render.c
Increased the maximum sphere rendering radius within RasMol.
This is the first step to producing high-resolution output.
[02/02/95] RS abstree.c abstree.h command.c tokens.h
Added support for selecting individual models in "nmrpdb"
files, either use "model=25" property or expression "::25".
RasMol also now allows chains to be specified ":a" and ":1".
[01/02/95] RS outfile.c
Modified the vector Postscript output routines to saturate
sphere colouring following "set ambient 100".
[23/01/95] RS abstree.c
Added the "%m" label format specifier for amino acid codes.
[20/01/95] RS render.c render.h rasmol.c x11win.c

Made functions CalcAngle and CalcDistance more robust.
[18/01/95] RS transfor.c transfor.h command.c command.h
Modified the RasMol "restrict" command to disable the display
of backbone, ribbons and strand representations. Labels??
[18/01/95] RS script.c
Corrected bug in Kinemage format output that occurred when
bonds were displayed in some chains but not in others. Also
fixed potential problems with backbone DNA hydrogen bonds
in Kinemage files. Thanks to Piotr Zimniak.
[18/01/95] RS command.c render.c x11win.c rasmac.c raswin.c abstree.
Added the options "distance", "angle" and "torsion" to
the RasMol "set picking" command to inspect geometry.
[17/01/95] RS command.c tokens.h render.c render.h
Added the RasMol command "set picking" with options "none",
"ident" (default) and "label". The final option toggles the
display of atom labels on the picked atom.

Added the "set write" command to allow "write" and "save"
commands to work from the command line.
[13/01/95] RS command.c tokens.h x11win.c
Added "refresh" command to update screen from script file.
[12/01/95] RS render.c

placed different residues in separate chains. Thanks to
Stefan Fischer.
[15/12/94] RS script.c
Fixed bug in WriteMolScriptFile that occasionally resulted
in all residues additionally being displayed as coil.
[13/12/94] RS molecule.c molecule.h command.c rasmol.c raswin.c
Added the "nmrpdb" file format to allow all NMR conformations
to be loaded into RasMol into different `models'.

[08/12/94] RS rasmol.c
Corrected bug in RasMol performance profiling routines.
[08/12/94] RS x11win.c
Improved support for monochrome X. The improved performance
algorithm now performs bidirectional error diffusion and
correctly handles Black/White bit variations (e.g NEC & SUN).
[30/11/94] RS molecule.c
Modified LoadAlchemyMolecule and ConnectAtoms to enable
hydrogen bonding to be specified in Alchemy format files.
Fixed bug with bond types. Thanks to Chris Wilson.

the Mac to 'vgrd' and 'TEXT' respectively. This enables
printing by Apple's PostScript utility. Thanks to Tom Jovin.
[29/11/94] RS x11win.c
Added support for Monochrome only X Windows displays by
dithering 8bit images before calling XPutImage. The current
error term diffusion algorithm may have to be improved for
wireframes and dot surfaces. Thanks to Cheuk-san Edward Wang.
[28/11/94] RS molecule.c
Made several changes to RasMol to account for unconventional
atom naming in PDB files, such as strange hydrogens 'HD',
'HG' and 'HH' and cysteine sulphurs ' SB1'. Thanks to Bruce
Livett.
[28/11/94] RS rasmol.doc
Added "primitives" to the keyword list in the on-line help
documentation to solve xref `bug'. Thanks to Steve Brenner.
