[osg-users] Making a Visible Vector
Hello World,
I am trying to create a visible vector that moves around a set space with one
point stationary. I have polling data which can be used for the polling
position of the dynamic point.
Here is how I set up my vector. I do not know how to create the vector visible
and then start to move the dynamic end point with relation to the stationary
end point.
The Vector just has to be a visible line that can be colored to make it stand
out from the background.
[code]
class orientVector : public osg::NodeCallback{
public:
orientVector::orientVector():
pos()
{};
orientCoords pos;
virtual void operator()(osg::Node* node, osg::NodeVisitor* nv)
{
pos.coordsCalc();
osg::PositionAttitudeTransform* moveVector =
dynamic_cast osg::PositionAttitudeTransform*(node);
//std::coutX - Value: pos.itsX Y - Value:
pos.itsY Z - Value: pos.itsZ std::endl;
moveVector-setPosition( osg::Vec3( pos.itsX, pos.itsY,
pos.itsZ));
traverse(node, nv);
}
};
/* DRAW THE FIRST VECTORS */
osg::Vec3Array* lineVisible1 = new osg::Vec3Array;
osg::Geode* lineVertex1 = new osg::Geode;
osg::Geometry* lineGeometry1 = new osg::Geometry;
lineVisible1-push_back( osg::Vec3 (511.33, 0, 767));
lineVisible1-push_back( osg::Vec3 (767, 767, 767));
lineGeometry1-setVertexArray( lineVisible1 );
lineVertex1-addDrawable(lineGeometry1);
// ORIENT THE VECTOR WITH IR DATA ***/
osg::PositionAttitudeTransform* vectorOrient = new
osg::PositionAttitudeTransform;
vectorOrient-addChild(lineVertex1);
vectorOrient-setUpdateCallback(new orientVector());
[/code]
I later on I will be setting up another vector at another static position so
that in the end there will be two vectors who point at one object as the
object moves through space.
...
I really appreciate all the help I can get! :D
Cheers,
Richard

Re: [osg-users] Creating a Visible Pivoting Vector/Cylinder
Hi Tom, Thanks a lot for your input. I will be coding that out today so hopefully I can get that all set up! Thanks again, more info on the situation as it develops! ...

[osg-users] Creating a Visible Pivoting Vector/Cylinder
Hi, I'm looking to write the code for a vector/a small diameter cylinder to pivot from the bottom, and traces to different points at the top with relation to data collected by a user interface device. Specifically I am tracking an IR LED with OSG in a cubic set space and would like a visible vector/cylinder to point to the LED's point in space. The vectors/cylinders are only for aesthetic purposes to get more of a feel of where the LED is in relation to the cubic defined space. Any/all help is greatly appreciated. I've been just learning this on my own and am new to OSG's specific operation! :-D ... Thank you!

[osg-users] Simple line construction in a 3d Space
Hey all!, I need to use a line in 3d space and hold one end fixed to a wall and then P.A.T. the other point through data which I am sending it in real time sort of like a tracker. I have a hunch to do this would be through the: osg::Geometry* newLine = new osg::Geometry(); but I'm not sure how to go about actually getting the line up and running. If you could help me with this preliminary code that would be great!

Re: [osg-users] Transparent Wall and Grid system Creation
Hi again, Thanks a lot for that code, I'm sure it will be a real help for me but I can't seem to create the geode and pass it to my addDrawable I'm getting an error of: [code] osg::Geometry* grid_sd = new osg::Geometry(); osg::Geode* grid_geode = new osg::Geode(); grid_geode-addDrawable(grid_sd); error C2512: 'osg::Geometry' : no appropriate default constructor available error C2664: 'osg::Geode::addDrawable' : cannot convert parameter 1 from 'osg::Geometry *' to 'osg::Drawable *'[/code] I don't know understand where to define an appropriate default constructor? ...

[osg-users] Transparent Wall and Grid system Creation
Hey All, Right now I am using OSG to code a cube for viewing an IR LED in 3DOF using 2 wiimotes. The problem I am running into right now is how to turn the walls of the cube transparent and interlace a grid in the cube to see three dimensional movement based on the vectors I have calculated to equate one point in three dimensional space for which it will run around inside of the cube. I am calculating the position of the 1 IR LED by triangulating the shortest vector between the lines of sight and taking its median. I am very new to OSG and only have a basic C++/C education. I am sorry if this is too trivial of a question. ... Thanks all!
