Revision
History:
HyperChem 7. 52
Professional Update
HyperChem 7.52 New Features
- Different rendering quality is possible for static and rotating molecules.
This allows one to use a faster, lower quality rendering while rotating
or moving a molecule, and a higher quality for a non-moving molecule.
- Alpha cylinder rendering now has the option to be capped.
- Ball and cylinder renderings now have the option to scale the balls by their
Van der Waals radii. Previously all balls were the same size.
- The width as well as the thickness of ribbons can now be modified.
Changes to HyperChem 7.5
- The red to green to blue rendering of isosurfaces has been reversed to use
red as the positive potential and blue as the negative potential.
- Isolated atom rendering has been changed to fix certain display problems.
- The tube display of double and triple bonds has modified (improved).
- Protein data bank files now use *.PDB as well as *.ENT for file extensions.
Corrections to HyperChem 7.5
- Aromatic rings now displayed correctly
- Dipole moments now displayed correctly
- The Raytrace feature is now compatible with the latest version of
POV-Ray.
- A bug in the QSAR module which incorrectly reported zero for the surface
area of large molecules has been fixed.
- A bug associated with certain graphics hardware that caused HyperChem to
eventually use up all its resources and disable a proper display has been fixed.
- The menu item, "Display/Show Isosurface", that toggled isosurfaces has been fixed.
- The F2 key that recovered the last rendering only worked the first time. It has
been fixed.
- A bug that sometimes caused the first displayed label to be colored differently
from other labels has been fixed.
- A bug that sometimes caused isosurface renderings to scale down in size after
bringing up "File/Preferences" has been fixed.
