Hi,
I´m new in OSG and I hope you can help me.
I´ve done a new constructor called "3dBox". In this constructor I wanna create
a cube.
Code:
mp_Quader2 = new Geode();
3dBox(*mp_Quader2);
this->addChild(mp_Quader2);
This is how I want it in the end. But it doesn´t work jet.
The constructor:
Code:
3dBox::3dBox(Geode *mQuader){
//mQuader = new Geode();
// Eigene Geometrie Klasse erzeugen
mGeom = new Geometry();
// Punktearray mit 6 Punkten für schrägen Quader
Vec3Array *vec3array = new Vec3Array();
Vec3Array *vec3array2 = new Vec3Array();
vec3array->push_back(Vec3(0.,0.,-50.));
vec3array->push_back(Vec3(200,0.,-50.));
vec3array->push_back(Vec3(200,100,-50.));
vec3array->push_back(Vec3(0.,100,-50.));
vec3array->push_back(Vec3(0.,0.,120));
vec3array->push_back(Vec3(150,0.,120));
vec3array->push_back(Vec3(150,100,300));
vec3array->push_back(Vec3(0.,100,300));
// Indexarray erzeugen
DrawElementsUInt *indarray = new
DrawElementsUInt(PrimitiveSet::QUADS,0);
indarray->push_back(0); indarray->push_back(1); indarray->push_back(2);
indarray->push_back(3);
indarray->push_back(4); indarray->push_back(5); indarray->push_back(6);
indarray->push_back(7);
indarray->push_back(0); indarray->push_back(1); indarray->push_back(5);
indarray->push_back(4);
indarray->push_back(3); indarray->push_back(2); indarray->push_back(6);
indarray->push_back(7);
indarray->push_back(0); indarray->push_back(3); indarray->push_back(7);
indarray->push_back(4);
indarray->push_back(1); indarray->push_back(2); indarray->push_back(6);
indarray->push_back(5);
mGeom->setVertexArray(vec3array);
mGeom-> addPrimitiveSet(indarray);
HfT_osg_StateSet *stateset = new
HfT_osg_StateSet(STRANSPARENT,Vec4(1.,0.,0.,0.5));
mGeom->setStateSet(stateset);
// Jetzt geom der geode zuweisen
mQuader->addDrawable(mGeom);
mQuader->setName("TestQuader");
mTrans = new MatrixTransform();
mTrans->addChild(mQuader);
}
In the header:
Code:
class 3dBox : public osg::Geode
Can you help me and explane to me why I can´t do
Code:
this->addChild(mp_Quader2);
and what I can do to make it work.
Important to say is when I do the thinks I do in the constructor in the class
it works fine.
Thank you!
Cheers,
Lukas
