Thank you very much, I shall test this and see that f it resolves my issues, by 
looking over it quickly I think it will.

I had to apply -90 (in degrees) to the pitch to get the correct results after 
getHPRFromQuat(). Also createMatrix is expecting the input in degrees. Maybe 
this will help

What do you think I maybe doing wrong with the following code : (NOTE: 
getHPRfromQuat is cut and paste from link, and the createMatrix is cut and

I was basically hoping that q2  ==  q after the conversion to and from

osg::Quat q(-0.7071067811865475, 0.0, 0.0, 0.7071067811865476);

osg::Matrixd m = createMatrix(0.0, 0.0, 0.0, hpr.x(), hpr.y(), hpr.z());
osg::Quat q2;
q2.set(m);
Any assistance is very much appreciated.

Hi Jason,

here you have YPR from osg::Quat (look at the snippets)

http://forum.openscenegraph.org/viewtopic.php?t=548

As for the other way it is easy, you create the Matrix and get the rotate Quat, 
(return matrix.getRotate()), something like:

osg::Matrixd Utils::createMatrix(double x, double y, double z, double h, double 
p, double r)
{
osg::Matrixd mxR;
mxR.makeRotate(osg::DegreesToRadians(r),osg::Vec3(0,1,0));
osg::Matrixd mxP;
mxP.makeRotate(osg::DegreesToRadians(p),osg::Vec3(1,0,0));
osg::Matrixd mxH;
mxH.makeRotate(osg::DegreesToRadians(h),osg::Vec3(0,0,1));
osg::Matrixd mxT;
mxT.makeTranslate(osg::Vec3(x,y,z));

return (mxP*mxH*mxT*mxR);
}

I had a look at those, maybe I can get it to work with them, but I really just 
want a simple 3 values for Yaw Pitch and Roll, from which I can re-create the 
exactly same Quat or Matrix.  I will also clarify, I don’t care about 
translation or scale etc, 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);

Hi NICK,

Thank you for your reply.

What do you think I maybe doing wrong with the following code : (NOTE: 
getHPRfromQuat is cut and paste from link, and the createMatrix is cut and 
paste from your reply.
I was basically hoping that q2  ==  q after the conversion to and from

osg::Vec3d hpr = getHPRfromQuat(q);

osg::Matrixd m = createMatrix(0.0, 0.0, 0.0, hpr.x(), hpr.y(), hpr.z());
osg::Quat q2;
q2.set(m);
Any assistance is very much appreciated.

decompose the matrix into translation, rotation, scale and scale

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

[Jason Anderssen]

Hi Chris,

Thank you for you reply.

I had a look at those, maybe I can get it to work with them, but I really just 
want a simple 3 values for Yaw Pitch and Roll, from which I can re-create the 
exactly same Quat or Matrix.  I will also clarify, I don’t care about 
translation or scale etc, 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

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?

decompose the matrix into translation, rotation, scale and scale 
orientation.

Will extract the trans, rot and scale components out of the matrix.

Is that what you want?

  The
void

 get

 (Matrixd

&matrix)
const

method lets you convert a Quat to a 4x4 Matrix.

void

 decompose

 (osg::Vec3d

 &translation, osg::Quat

 &rotation, osg::Vec3d

 &scale

, osg::Quat

&so)
const decompose the matrix into translation, rotation, scale and scale
orientation.

Will extract the trans, rot and scale components out of the matrix.

Is that what you want?
