Re: [osg-users] Yaw pitch and roll or xyz conversion to and from Quaternion

(in degrees) to the pitch to get the correct results after getHPRFromQuat(). Also createMatrix is expecting the input in degrees. Maybe this will help Nick On Fri, Dec 19, 2014 at 3:10 AM, Jason Anderssen janders...@exactal.commailto:janders...@exactal.com wrote: Hi NICK, Thank you for your reply

[osg-users] Yaw pitch and roll or xyz conversion to and from Quaternion

Hi all, Just wondering if in OSG there is anywhere I can extract either Yaw pitch and roll / or XYZ eular angles, too and from either a matrix or a quaternion? Thank you in advance. Cheers Jason Anderssen Internet Email Confidentiality Footer: This email and any files transmitted

Re: [osg-users] Yaw pitch and roll or xyz conversion to and from Quaternion

, and the quaternion I am using is of course only a rotation anyway. So basically I want the following type of code : getYPR(float yaw, float pitch, float roll); Quaternion::fromYPR(yaw, pitch, roll); Cheers Jason Anderssen From: Chris Hanson xe...@alphapixel.commailto:xe...@alphapixel.com Reply

[osg-users] 3d control in scene (ignore scene depth test)

Hi, Just a simple question that you probably will know the answer too. If I want to have a control in the scene, but I don’t want this object to obey the depth testing against the scene itself, how do I go about this. For example, the scene has a building, and I want to position an axis control

[osg-users] Matrix makeLookAt and getLookAt

Hi all, Just a simple question, I have now found a need to use LookAt functions, but I don’t understand something, I create a matrix using lookAt, but when I call getlookAt, it does not give the same results back I originally used when creating it. Any ideas? Code : osg::Vec3d eye(0.0,

[osg-users] Pivot point in osgViewer

Hi all, Im experimenting with osgViewer, and would like to know how I would go about changing the pivot point of the scene if the user clicks on an object and I want to use the scenes object's centre point as the new pivot point? Is this possible with the current manipulators? So ultimately I

Anyone got a suggestion for this, or am I in the wrong forum for this question ? (i.e. does OSG have a way to do the zoom to object animation as outlined below ? ) Cheers Jason On 13/06/2012, at 8:41 AM, Jason Anderssen wrote: Torben, Thanks for reply, and it works perfectly. However

Torben, Thanks for reply, and it works perfectly. However is there a way to make it animate to the zoom points. I have a Nodetracker-Manipulator set as my default manipulator, and I change the node path as the user selects objects from the scene, it would be nice if I could animate the zoom

[osg-users] zoom to object with camera

Hi all, Hope this is a simple question, in OSG is there a simple way to move the camera so it is viewing the extents of a particular geode in the current scene (e.g. the user selects an object and the camera zooms to it) ? Even better would be is it possible to calculate the new camera position
