Hi,
I'm having some trouble using CGO spheres. When I create one, it is not
visible in the viewer, although there is an (apparently empty) object in
the object pane. It is somewhat confusing because with some parameters
the spheres ARE visible when ray tracing, although they are still not
visible when non ray traced.
I have not had this problem in the past, although I haven't tried in a
while (> 1 year).
I am using pymol v1.7.4.0 which is up to date from the SVN repository
(revision 4107). And I am on Ubuntu 14.04. I reproduced this problem on
another computer running 1.7.x.
To reproduce:
pymol -k #to eliminate setting in the .pymolrc
In pymol:
from pymol.cgo import *
sph1 = [BEGIN, ALPHA, 0.5, COLOR, 1.0, 1.0, 1.0, SPHERE, -3.818,
-28.181, -15.016, 0.5]
cmd.load_cgo(sph1, "sph1", 1)
This loads a seemingly empty object that is not visible when ray tracing.
Setting the Alpha parameter to 1.0 allows it to be visible when ray
tracing, but not under normal conditions.
sph2 = [BEGIN, ALPHA, *1.0***, COLOR, 1.0, 1.0, 1.0, SPHERE, -3.818,
-28.181, -15.016, 0.5]
cmd.load_cgo(sph2, "sph2", 1)
Do you have any idea what the problem might be or settings that I could
check?
Thanks,
Matt Baumgartner
