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
Why is it shown leaning?How can I solve that?
