Re: [PyMOL] CGO rotate vs quaternion

Hi Pawel, Have a look here: http://euclideanspace.com/maths/algebra/realNormedAlgebra/quaternions/index.htm It should provide some insight into what quaternions are and how you can use them to rotate or obtain an axis-angle representation. Cheers, Tsjerk On Sun, Nov 24, 2013 at 11:31 PM, Паве

Jason, My drivers are newest Nvidia 331.82 from http://www.nvidia.pl/download/driverResults.aspx/70559. I'm not sure if the problem is on my site or no. Maybe my pymol distribution is badly built? What else can I do to get rid of that bug? Cheers, Pawel 2013/11/24 Jason Vertrees : > Hi Pawel, > >

Hi Pawel, I suggest making sure that your video drivers are up to date at all times when using software like PyMOL. Mobile video cards notoriously badly implement the OpenGL spec. If that's a bug in our part, we'll try to track it down. Cheers, -- Jason On Sun, Nov 24, 2013 at 3:42 PM, Павел

[PyMOL] CGO rotate vs quaternion

2013-11-24 Thread Павел Томашевский
Hi all, Ok, so today I have to admit that I don't know what quaternions are but I will need to use them. I'm working on PyMOL and Sensable Phantom Omni haptic device integration using Virtual Reality Peripherial Network (VRPN). So far I have a nicely working plugin for PyMOL that can retreive X,

Hi, Is there any chance you can send me your input file(s)? Also, please let me know what computer, video card, and architecture (32-bit/64-bit) you're running on. Cheers, -- Jason On Sat, Nov 23, 2013 at 2:47 PM, Павел Томашевский wrote: > Hello > I run PyMol 1.6.0 on windows 7 and I get thi
