20130829 07:08:28 <odinsbane> I have a plane, where I know the normal and center of mass. I'm trying to rotate a plane to that normal. Is there a prefered way to do this?
20130829 07:24:22 <xranby> (01:59:37) hrenovka: so now i'm reading openal specification <-- great :)
20130829 07:28:17 <xranby> odinsbane: http://www.arcsynthesis.org/gltut/Positioning/Tutorial%2008.html you may want to take a look at this tutorial to get a better understanding about rotations.
20130829 07:28:29 <xranby> JogAmp JOGL 2.0.2 code for this tutorial exist here: https://github.com/elect86/modern-jogl-examples
20130829 07:29:11 <xranby> you can quickly build this tutorial from scratch if you have "maven" mvn installed on your system
20130829 07:29:37 <xranby> git clone https://github.com/elect86/modern-jogl-examples
20130829 07:29:48 <xranby> cd modern-jogl-examples
20130829 07:29:49 <xranby> mvn install
20130829 07:29:56 <xranby> mvn exec:java -Dexec.mainClass="tut08.CameraRelative"
20130829 07:30:10 <xranby> mvn exec:java -Dexec.mainClass="tut08.CameraRelative"
20130829 07:36:08 <xranby> the modern jogl examples require OpenGL 3 and later drivers
20130829 07:38:18 <xranby> i will be back.. switching GPU on this machine
20130829 07:38:39 <odinsbane> I've been through that tutorial awhile ago.
20130829 07:39:16 <xranby> ok, did the follow up discussions give any good hints on how to solve your specific plane rotation issue?
20130829 07:39:28 <xranby> sounds to me the best reading is a book on mathematics
20130829 07:39:38 <odinsbane> my mathematics if fine.
20130829 07:40:11 <odinsbane> Would you resort to using quaternions for this. I haven't used them much. I can use basic vector math to solve the problem.
20130829 07:40:42 <odinsbane> It is just the transform3d has so many different methods I might be missing something.
20130829 07:41:17 <xranby> then any way you solve it that archive the desired results is fine, i doubt you will run into any performance issues reguardless which implementation you choose
20130829 07:41:48 <xranby> quaternions may be handy to use if you want to interpolate between two rotations easily
20130829 07:44:09 <odinsbane> What are the follow up discussions?

20130829 07:45:31 <xranby> i was refering to those links to be the follow up discussions
20130829 07:45:36 <odinsbane> xranby: I wouldn't refer to those as follow ups. They seem to be part of 8 sorry.
20130829 07:49:25 <xranby> odinsbane: if you have worked more on these tutorials it would be cool if you helped elect86 to complete the jogl ports of the tutorials https://github.com/elect86/modern-jogl-examples
20130829 07:50:01 <xranby> he have only ported tutorial 1 - 9
20130829 07:51:50 <odinsbane> That is an interesting prospect. I have worked through the tutorials in c++ and I use java3d.
20130829 07:52:04 <odinsbane> So I don't have any pre-existing code that would help.
