Summary0029985: Visualization - Wrong result of V3d_View::FitAll() for a straight line segment
DescriptionWhen I try to display a line laying on the plane (0, 0, 1, -4000), the FitALL function goes wrong (I can't see anything on the View window because of clipping). I think this is related to the calculation of zNear/zFar.
Steps To Reproduce
pload MODELING VISUALIZATION
vclear
vinit View1
vtop
vpoint p1   0 0 4000
vpoint p2 200 0 4000
vsegment s p1 p2
vfit


1) Set orientation of projection:
  myView->setProj(V3d_Zpos);
2) Make an edge:
  TopoDS_Edge edge = BRepBuilderAPI_MakeEdge(gp_Pnt(0.0, 0.0, 4000.0), gp_Pnt(200.0, 0.0, 4000.0));
3) Display the shape:
 Handle(AIS_Shape) edgeShape = new AIS_Shape(edge);
 myContext->Display(edgeShape, true);
4) Call fitALL:
 myView->FitALL();
TagsNo tags attached.
