Re: [PyMOL] Yaw, Pitch and Roll of CGO
Jared, my haptic device is SensAble Phantom Omni and now it is called
Geomagic Touch. I work on integration it with PyMOL and VRPN.
So far so good, but now I have a little more complicated problem with
rotate and translate functions.
When I set camera=0 in both of them, it doesn't matter if I move the screen
with mouse or not - my cone rotations and translations are absolute to the
global origin.
But when I don't set camera=0 option translations of the cone still works
well but rotations don't.
I think this is because translate function gets coordinates that are not
absolute to the origin but it gets changes - I mean [dx, dy, dz], where
dx=|x-x0|, x is current position and x0 is previous position (the same with
dy and dz). On the other hand rotate function gets origin option params as
absolute values, here [x, y, z] are cone position. Now after turning camera
with mouse translations of the cone are relative to camera position but
origin of rotation is absolute to main coordinate system position.
In this situation I have two origins: origin of rotations that is equal to
position of the cone and some global PyMOL origin where everything begins.
I hope it's clear so far ;)
Now, is it possible to change the origin of rotation not with values that
are absolute to the global origin but with changes relative to it's
previous position. Or maybe I should ask: "Is it possible to CHANGE origin
of rotation, not to SET it?".
I know it's a little complicated to explain what I mean using words, but I
hope I succeeded here ;)
Cheers,
Paweł

Re: [PyMOL] Yaw, Pitch and Roll of CGO
Hi Pawel -
Glad you were able to make it work. Also, that haptic device (I guess the new
version is the Geomagic Touch?) looks pretty neat.
I'm now realizing that when you asked "how to make a rotation of the CGO about
axis that is NOT of the global pymol coordinate system but goes through the CGO
itself" you probably didn't necessarily mean a rotation about the cone's
primary axis, because that doesn't really do a whole lot unless your object
isn't radially symmetric!
For correctness' sake, however, I need to amend my previous response. It turns
out I chose unfortunate values for the cone base and tip positions in my
example, which resulted in the cone axis going through the global coordinate
origin. My previous attempt fails for cones that don't point at or away from
the origin. Whoops!
Thomas' suggestion about the origin argument fixes it, though. So for my
example, I'd also need either the tip or the base position:
# print the values to use later
print "tip_xyz = %s" % tip_xyz # need this, too!
print "axis = %s" % cone_axis
and then rotate the cone with, e.g.:
rotate [3,3,3], 10, object=cone, camera=0, origin=[4,5,6]
or everything with, e.g.:
rotate [3,3,3], 10, origin=[4,5,6]
Cheers,
Jared

Hi Pawel -
If you can determine the primary axis of the cone from the tip and the center
of the circle at the base, you can give `rotate` an arbitrary [x,y,z] float
vector as its first argument instead of x, y or z. For example, if you
generate your cone using something like the following Python script:
### cone_cgo.py ###
from pymol.cgo import *
from pymol import cmd
# set up the cone
base_xyz = [1.0, 2.0, 3.0]
tip_xyz = [4.0, 5.0, 6.0]
base_radius = 1.0
tip_radius = 0.0
base_color = [0.9, 0.0, 0.0]
tip_color = [0.0, 0.0, 0.9]
# calculate the cone axis
cone_axis = [ tip_xyz[0]-base_xyz[0],
tip_xyz[1]-base_xyz[1],
tip_xyz[2]-base_xyz[2] ]
# print the axis to use later
print cone_axis
# generate the cone CGO text
obj = [CONE, base_xyz[0], base_xyz[1], base_xyz[2], tip_xyz[0], tip_xyz[1],
tip_xyz[2], base_radius, tip_radius, base_color[0], base_color[1],
base_color[2], tip_color[0], tip_color[1], tip_color[2], 1, 1]
# load it
cmd.load_cgo(obj, 'cone')
# generate a pseudoatom for reference
cmd.pseudoatom('point', pos=[2,5,4])
cmd.show_as('nb_spheres', 'point')
### end cone_cgo.py ###
and load it via `run cone_cgo.py`, then you can rotate the cone on its axis
using, e.g.:
rotate [3,3,3], 10, object=cone, camera=0
Even with a radially symmetric cone surface, if you look closely, you can see
the individual polygons changing at the cone base. You can also rotate the
scene around the cone axis with, e.g.:
rotate [3,3,3], 10
Hope that helps.
Cheers,
Jared

Re: [PyMOL] Yaw, Pitch and Roll of CGO
Hi Pawel -
If you can determine the primary axis of the cone from the tip and the center
of the circle at the base, you can give `rotate` an arbitrary [x,y,z] float
vector as its first argument instead of x, y or z. For example, if you
generate your cone using something like the following Python script:
### cone_cgo.py ###
from pymol.cgo import *
from pymol import cmd
# set up the cone
base_xyz = [1.0, 2.0, 3.0]
tip_xyz = [4.0, 5.0, 6.0]
base_radius = 1.0
tip_radius = 0.0
base_color = [0.9, 0.0, 0.0]
tip_color = [0.0, 0.0, 0.9]
# calculate the cone axis
cone_axis = [ tip_xyz[0]-base_xyz[0],
tip_xyz[1]-base_xyz[1],
tip_xyz[2]-base_xyz[2] ]
# print the axis to use later
print cone_axis
# generate the cone CGO text
obj = [CONE, base_xyz[0], base_xyz[1], base_xyz[2], tip_xyz[0], tip_xyz[1],
tip_xyz[2], base_radius, tip_radius, base_color[0], base_color[1],
base_color[2], tip_color[0], tip_color[1], tip_color[2], 1, 1]
# load it
cmd.load_cgo(obj, 'cone')
# generate a pseudoatom for reference
cmd.pseudoatom('point', pos=[2,5,4])
cmd.show_as('nb_spheres', 'point')
### end cone_cgo.py ###
and load it via `run cone_cgo.py`, then you can rotate the cone on its axis
using, e.g.:
rotate [3,3,3], 10, object=cone, camera=0
Even with a radially symmetric cone surface, if you look closely, you can see
the individual polygons changing at the cone base. You can also rotate the
scene around the cone axis with, e.g.:
rotate [3,3,3], 10
Hope that helps.

Hello I've made a cone CGO (something like a pointer) and now I need to make a rotation of the cone. I have got yaw, pitch and roll angle values, but when I do 'rotate' command it rotates about axis of the global coordinate system. My question is, how to make a rotation of the CGO about axis that is NOT of the global pymol coordinate system but goes through the CGO itself? I hope it's clear what I mean ;) Thank you Pawel -- Managing the Performance of Cloud-Based Applications Take advantage of what the Cloud has to offer - Avoid Common Pitfalls.
