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

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);

[osg-users] [forum] Resize Geometry in a HUD on Resize of Window
Hi all, My goal is to have a HUD that consists of one circle drawn programmatically. I followed the osgHUD example and was able remove the text they draw and draw my circle instead. I did this by adding a (circle) Geometry to the Geode and removing the text and bounding box from the Geode. My problems: 1) When I resize my window, my circle gets deformed into an ellipse. Why is this? And how do I keep my circle from deforming on window resize? 2) Currently I am using: hud_camera-setProjectionMatrix(osg::Matrix::ortho2D(0, 1280, 0, 1024)); but I want my program to work with any screen resolution (not just 1280x1024). How do I obtain the screen resolution of the screen my program is running on? If you could give me an answer using osgHUD as a reference that'd be especially great! Thanks so much!

Re: [osg-users] [forum] Resize Geometry in a HUD on Resize of Window
Hi John-Luke,
Uf the HUD camera is assigned to the GraphicsContext then when it's
resized the projection matrix can be adjusted automatically if
required. In osg::Camera there is the following control:
enum ProjectionResizePolicy
{
FIXED, /** Keep the projection matrix fixed, despite
window resizes.*/
HORIZONTAL, /** Adjust the HORIZONTAL field of view on
window resizes.*/
VERTICAL /** Adjust the VERTICAL field of view on window resizes.*/
};
/** Set the policy used to determine if and how the projection
matrix should be adjusted on window resizes. */
inline void setProjectionResizePolicy(ProjectionResizePolicy
policy) { _projectionResizePolicy = policy; }
/** Get the policy used to determine if and how the projection
matrix should be adjusted on window resizes. */
inline ProjectionResizePolicy getProjectionResizePolicy()
const { return _projectionResizePolicy; }
If the HUD Camera is embedded in the scene graph this automatic
adjustment isn't active so you'd need to manually manage it by
checking for resize events.
Robert.

[osg-users] [vpb] Roads as Shapefiles in VPB?
Hi All, I have road geometry (3D) that I might be able to convert to SHP file using shapelib library. If I load the shapefile for the road, shall I expect the terrain in VPB to be modified to accompany the road on top? My Aim: Wherever the road is present, the terrain must be flattened (go below the road). At least, VPB experts can be able to tell if this is feasible with existing SHP file support in VPB?

Re: [osg-users] [vpb] Roads as Shapefiles in VPB?
Hi Robert, After posting this, I quickly realized that SHP files might be doing some sort of draping rather than modifying the terrain. Anyway,It will not do the job I Feel now. There was osgTDS (Terrain Deformation s/w) sometime back. Now it seems to be out of shape. That was doing something similar to what I trying to achieve. Isn't it? I do not prefer osgEarth. VPB satisfies my needs good enough except with this road issue. Anything you can suggest to try out to modify Terrain to adjust to my 3D roads (using VPB/ osgTerrain etc)? I can try out your concepts. Please reply to this part if you have little spare time :) . Thank you!

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