Hi Paul,
I have been using CCPEMs coot (version 0.9.8.5) for a while but
decided to change to ccp4 to get the newest updates (coot version
0.9.8.91). I have noticed that something in the graphics has changed.
In version 0.9.8.91 there is pretty noticeable aliasing, which is not
a problem in version 0.9.8.5 packaged with ccpem.
If I may so bold, I'd suggest the Subject of the post is not correct. It
should be "Coot has worse aliasing in CCP4 builds than in CCPEM builds"
For reasons that I don't understand, CCP4 have historically been
reluctant to add the antialiasing patch into the build of Coot (one of
its dependencies, just to be clear) - hence Coots from CCP4 have never
had antialiasing. CCPEM developers have taken on board the anitaliasing
patch and so their Coots look smoother.
I have attached a picture to show this (I am using the default colors
in both). I am on Mac M1 with MacOS Ventura 13.5.2.
I know there is an antialiasing option, but it makes the lines on the
map thicker and it is more difficult to see.
Yes, I should have removed that years ago. I now know enough about
OpenGL and graphics drivers to know that this function would never be
able to do what I wanted it to do.
FWIW, Things are different in the new version of Coot. All builds are
non-antialiased (boo). But on macOS, Coot is now native and runs at
retina resolution and so looks (again, if I may be so bold) rather
attractive (yay).
Regards,
Paul.
