Re: [osg-users] pfDCS replacement
Is there any reason it gets converted to a MatrixTransform object rather than a PositionAttitudeTransform object?

PositionAttitudeTransform provides finer control over the generation of the matrix so can be ore convinient to use, but there really isn't any directly equivalent in Performer.

Re: [osg-users] pfDCS replacement
Hi Tony Have you take a look to osg/src/osgPlugins/pfb/* source code ? this plugin load pfb fie in osg, so I think many answers of your question will be there. HTH David 2015-08-28 5:34 GMT+02:00 Tony Vasile ming...@gmail.com: Okay today I am wondering which class replaces pfDCS in OSG? A Google search shows there use to be a class osg::DCS but this has been removed. To get the same functionality do I use PositionAttitudeTransform?

[osg-users] Animation problem
Hi,
Can't figure out what is the problem. I'm trying to modify geometry depending
on time. But I'm getting an exception std::__non_rtti_object at memory
location.. or application triggers a breakpoint.
Code:
void SurfaceCalculationThread::run()
{
while (!done)
reCalculateSurface();
};
float SurfaceCalculationThread::calculateZ(float x, float y, float t)
{
float z;
z = sqrt(((x*x) / (B*B)) + ((y*y) / ((A*A)*(sin(t)*sin(t + 1);
return z;
}
void SurfaceCalculationThread::reCalculateSurface()
{
float x, y, z;
int i = 0;
float something = (sqrt(Npolygon) / 2)*1.00;
t=time-elapsedTime_n();
for (x = -something; x = something; x += 1.0f)
{
for (y = -something; y = something; y += 1.0f)
{
(*vertices2)[i].set((*vertices)[i]);
z = calculateZ(x, y, t);
(*vertices)[i].set(osg::Vec3f(x, y, z));
i++;
}
}
geometry-setVertexArray(vertices2);
geometry-setUpdateCallback(new UpdateSurfaceCallback(vertices));
}
Thank you!
Cheers,
Julie

Re: [osg-users] LOS materail query
OK,
Got this working for some cases. For example, I used Lightwave to create a
box with a colorbar texture placed on it so I would know for sure that the
color returned was correct. The texture I used was a plain jpg. The problem is
when using some other .ive , ost, or .osgt files. These have embedded textures
of some unknown format. Do I need to somehow use set/getPixelFromat in order to
be able to retrieve to right values for the texture color ?
I am using this to check the color values for the picked texture:
Code:
osg::Image *myImage = myTexture-getImage(0);
if (myImage) {
osg::Vec4 textureColor =
myImage-getColor(tc);
std::cout textureColor =
textureColor.x()*255 , textureColor.y()*255 ,
textureColor.z()*255 std::endl;
}
Thank you!
Cheers,
Mike

[osg-users] Adding custom updater to the Viewer
Hi All, In my application class I'm currently inheriting the osg::Viewer and doing my own run function. It is basically a copy paste of the osg::Viewer function just so I can add my own custom update code for networking, entities, etc... Is there a way in osg I can do that without having to do this override? Thanks, Sam ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org
