Hello,
I want display two trihedron on my Context.one in the center of my context and the second in the corner(in the left low).
I used gp_Trsf aTrsf; aTrsf.SetTranslation(gp_Vec(10,15,-20));but I not found a good result. In addition I used setlocation but also I hadn't a result
In addition want to extend an axis without using the zoom but I don't found any result.
Regards

here is the code
//Create and display a trihedron in the viewer
Handle(AIS_Trihedron) aTrihedron;
Handle(AIS_Trihedron) aTrihedron1;
// 1er trihedron
Handle(Geom_Axis2Placement) anAxis=new Geom_Axis2Placement(gp::XOY());
aTrihedron1=new AIS_Trihedron(anAxis);
myAISContext->Display(aTrihedron1);
///2 trihedron)
Handle(Geom_Axis2Placement) anAxis2=new Geom_Axis2Placement(gp::XOY());
aTrihedron=new AIS_Trihedron(anAxis2);
aTrsf.SetTranslation(gp_Vec(10,15,-20));
aTrihedron->SetLocation(aTrsf);
myAISContext->Display(aTrihedron);

I found how I can change the size of a graduation using setSize () but I have not figured out how I can display two graduations in which the second is at the bottom left.
does it have someone who can help me

Hi! You must for the top left position:
myView->ZBufferTriedronSetup (Quantity_NOC_RED, Quantity_NOC_GREEN, Quantity_NOC_BLUE1, 0.2, 0.05,12);
myView->TriedronDisplay( Aspect_TOTP_CENTER, Quantity_NOC_GRAY30, 0.2, V3d_ZBUFFER);
And here the default Acpect values:
Aspect_TOTP_CENTER,
Aspect_TOTP_LEFT_LOWER,
Aspect_TOTP_LEFT_UPPER,
Aspect_TOTP_RIGHT_LOWER,
Aspect_TOTP_RIGHT_UPPER,
Aspect_TOTP_01,
Aspect_TOTP_02,
Aspect_TOTP_03,
Aspect_TOTP_04,
Aspect_TOTP_05,
Aspect_TOTP_06,
Aspect_TOTP_07,
Aspect_TOTP_08,
Aspect_TOTP_09,
Aspect_TOTP_10

Thank you juryS,
I use this method(myView->TriedronDisplay) but the Triedrondoes not display.
I use myAISContext for displaying

For me I make my Triedron with 3 Edges and 3 Cone. I'm know that It's no good idea, but I can't work with default OCC triedron.
I'm programming with QT and I want to make triedron with QT GL widget.

I want to use myview for displaying a trihedron.
below the code I used:
const Handle(V3d_View) myView=myAISContext->CurrentViewer()->CreateView();
myView->ZBufferTriedronSetup (Quantity_NOC_RED, Quantity_NOC_GREEN, Quantity_NOC_BLUE1, 0.2, 0.05,12);
myView->TriedronDisplay( Aspect_TOTP_CENTER, Quantity_NOC_GRAY30, 0.2, V3d_ZBUFFER);
using this code nothing appears
I would display the trihedron

It's very strange. What are system you are use? There any problem with your V3dViewer. Maybe your code is wrong???
Try to add this 2 lines in default sample and then you are see that it's can work. After you can find wich a problem with your viewer.
Else take your E-mail I show you my code.

Thank you very much JuryS for your help.
My problem is when I run this lines but no view display.
My OS is Windows XP SP2. And I use VC++ 2008.
My E-mail is mounaattia.info@gmail.com

when I compile or when I run, no error appears but also the view doesn't display.

Hi! In my project I'm use two functions for displaying Triedron:
void tempView::ShowMyTriedron(const double myScale)
{
double mySize = 100 * 1/myScale;
double myDiam = 6 * 1/myScale;
double myCylLength = mySize - mySize/5;
double myLineWidth = myDiam/3;
BRepBuilderAPI_MakeEdge myCoordXcyl(gp_Pnt(0,0,0),gp_Pnt(myCylLength,0,0));
gp_Pnt myCoordXConeA(myCylLength,0,0);
gp_Pnt myCoordXConeB(mySize,0,0);
gp_Vec myCoordXConevec(myCoordXConeA, myCoordXConeB);
gp_Dir myCoordXConedir(myCoordXConevec);
gp_Ax2 myCoordXConeax2( myCoordXConeA, myCoordXConedir );
BRepPrimAPI_MakeCone myCoordXcone(myCoordXConeax2, myDiam, 0, mySize-myCylLength);
BRepBuilderAPI_MakeEdge myCoordYcyl(gp_Pnt(0,0,0),gp_Pnt(0,myCylLength,0));
gp_Pnt myCoordYConeA(0,myCylLength,0);
gp_Pnt myCoordYConeB(0,mySize,0);
gp_Vec myCoordYConevec(myCoordYConeA, myCoordYConeB);
gp_Dir myCoordYConedir(myCoordYConevec);
gp_Ax2 myCoordYConeax2( myCoordYConeA, myCoordYConedir );
BRepPrimAPI_MakeCone myCoordYcone(myCoordYConeax2, myDiam, 0, mySize-myCylLength);
BRepBuilderAPI_MakeEdge myCoordZcyl(gp_Pnt(0,0,0),gp_Pnt(0,0,myCylLength));
gp_Pnt myCoordZConeA(0,0,myCylLength);
gp_Pnt myCoordZConeB(0,0,mySize);
gp_Vec myCoordZConevec(myCoordZConeA, myCoordZConeB);
gp_Dir myCoordZConedir(myCoordZConevec);
gp_Ax2 myCoordZConeax2( myCoordZConeA, myCoordZConedir );
BRepPrimAPI_MakeCone myCoordZcone(myCoordZConeax2, myDiam, 0, mySize-myCylLength);
if (hasTriedron)
{
myCoordX->Set(myCoordXcyl.Shape());
myContext->Redisplay(myCoordX,0);
myCoordXCone->Set(myCoordXcone.Shape());
myContext->Redisplay(myCoordXCone,0);
myCoordY->Set(myCoordYcyl.Shape());
myContext->Redisplay(myCoordY,0);
myCoordYCone->Set(myCoordYcone.Shape());

myCoordZ->Set(myCoordZcyl.Shape());
myContext->Redisplay(myCoordZ,0);

}
else
{
myCoordX = new AIS_Shape(myCoordXcyl.Shape());
myContext->SetWidth(myCoordX,myLineWidth,Standard_False);
myContext->SetColor(myCoordX,Quantity_NOC_RED,Standard_False);
myContext->SetMaterial(myCoordX,Graphic3d_NOM_PLASTIC,Standard_False);
myCoordXCone = new AIS_Shape(myCoordXcone.Shape());
myContext->SetColor(myCoordXCone,Quantity_NOC_RED,Standard_False);
myContext->SetMaterial(myCoordXCone,Graphic3d_NOM_PLASTIC,Standard_False);
myCoordY = new AIS_Shape(myCoordYcyl.Shape());

myContext->SetMaterial(myCoordZCone,Graphic3d_NOM_PLASTIC,Standard_False);
hasTriedron = true;
}
myContext->Display(myCoordX,1,-1,Standard_True,Standard_False);
myContext->Display(myCoordXCone,1,-1,Standard_True,Standard_False);
myContext->Display(myCoordY,1,-1,Standard_True,Standard_False);
myContext->Display(myCoordYCone,1,-1,Standard_True,Standard_False);
myContext->Display(myCoordZ,1,-1,Standard_True,Standard_False);
myContext->Display(myCoordZCone,1,-1,Standard_True,Standard_False);
}
void tempView::HideMyTriedron()
{
myContext->Clear(myCoordX,Standard_False);
myContext->Clear(myCoordXCone,Standard_False);
myContext->Clear(myCoordY,Standard_False);
myContext->Clear(myCoordYCone,Standard_False);
myContext->Clear(myCoordZ,Standard_False);
myContext->Clear(myCoordZCone,Standard_False);
}
where the scale = myView->Scale();
When I'm the rotation, then I'm hide my triedron and then show him with new Scale.
If you are using QT I may make for you the sample for QT with using V3d_Triedron. And you can run this with compiling *.pro file of QT.
You are need this ???
