Hello,
If I read a STEP file that contains the model of a mug (see mug.png) and I try to represent it by the V3d_View with the parameters shown below, I get the view shown in view.png :
aView->Camera()->SetCenter(centre); //Look-at point of the camera
aView->Camera()->SetDirection(gp_Dir(-1., 0., 0.)); //Camera direction
aView->Camera()->SetDistance(200.0); //Camera distance
aView->Camera()->SetProjectionType(Graphic3d_Camera::Projection_Perspective);
Why is it shown leaning?How can I solve that?
Thanks!

Hi Adriana,
I'm new to OCCT and I've been trying to build a visualizer for my application. I'm finding it difficult to launch a widget which renderes my geometry and was hoping you could help. Would it be possible for you provide me a small example of your code for the viewer?

Hi Pranav,
Here you are.
static Handle(OpenGl_GraphicDriver) aGraphicDriver;
Handle(Aspect_DisplayConnection) aDisplayConnection;
#if !defined(_WIN32) && !defined(__WIN32__) && (!defined(__APPLE__) || defined(MACOSX_USE_GLX))
aDisplayConnection = new Aspect_DisplayConnection(getenv("DISPLAY"));
#endif
aGraphicDriver = new OpenGl_GraphicDriver(aDisplayConnection);
// creating the Viewer
Handle(V3d_Viewer) aViewer = new V3d_Viewer(aGraphicDriver);
aViewer->SetDefaultLights();
aViewer->SetLightOn();
// creating a View
Handle(V3d_View) aView = aViewer->CreateView();
Handle(Xw_Window) W = new Xw_Window(aDisplayConnection, "Test V3d", 0.5, 0.5, 500, 500);
// Map this Window to this screen
if (!W->IsMapped()) {
W->Map();
}
// the Interactive context
Handle(AIS_InteractiveContext) aContext = new AIS_InteractiveContext(aViewer);
Handle(AIS_Shape) anAISShape = new AIS_Shape(result);
Standard_Integer mode = 1;
aContext->SetDisplayMode(mode, Standard_False);
aContext->Display(anAISShape);
aView->SetWindow(W);
