| Summary | 0033514: Visualization - Scaled view twists zoom persistence objects | ||||
| Description | Objects like manipulators with zoom persistence need to maintain its visual aspects for proper usage in a scene. The application of a visual scale is twisting its effects (see figure zoom_scaled.png). A similar effect was observed in issue https://tracker.dev.opencascade.org/view.php?id=27832. The proposal is to adjust the zoom persistent object scale according to the view's axial scale. | ||||

Dear Marina, please review changes made to the behaviour of zoom persistence objects. The tests in jenkins do not produce errors connected to these particular changes (http://jenkins-test-10.nnov.opencascade.com/view/CR33514-master-drochalo/view/COMPARE/). |

This is wrong The scale must be applied to all objects with Graphic3d_TMF_ZoomPers except the manipulator.
//Adjust the camera axial scale for zoom persistent objects
gp_XYZ anAxialScale = theCamera->AxialScale();
Standard_Real anAxialX = anAxialScale.X();
Standard_Real anAxialY = anAxialScale.Y();
Standard_Real anAxialZ = anAxialScale.Z();
if (anAxialX > 0 && anAxialY > 0 && anAxialZ > 0)
{
Graphic3d_TransformUtils::Scale(aWorldView, 1.0 / anAxialX, 1.0 / anAxialY, 1.0 / anAxialZ);
}
