| Summary | 0025845: VIS - Surface normals to be associated with polygonal source | ||||||||||||
| Description | Currently in IVtk it is not possible to use original geometric normals in triangulation nodes. These normals are required in order to enhance visualization smoothness. Currently IVtk client code is forced to use vtkPolyDataNormals filter in couple with Phong/Gouraud shading mode, but this does not help much (see screenshot attached). Once fixed, the official user's guide on IVtk has to be reviewed (I think, currently it contains some notes on necessity to use vtkPolyDataNormals). | ||||||||||||

What is the status of this issue? is it going to be fixed in OCCT 6.9.0? |

Put the "unscheduled" version as there is no demand currently in fixing the reported issue. Applying vtkPolyDataNormals filter gives a sufficiently smooth presentation of curved geometry. |
