Summary

0000687: VRMLExporter bug fix

Description

If you use field data to color, VRMLExporter didn't pick up on it.

These few lines seem to fix it for me - I'm not sure how to submit a bug
fix:

In VRMLExporter.cxx (Revision 1.68, VTK 4.2), after line 301
(pm->SetScalarMode), add:

  if ( pm->GetScalarMode() == VTK_SCALAR_MODE_USE_POINT_FIELD_DATA ||
       pm->GetScalarMode() == VTK_SCALAR_MODE_USE_CELL_FIELD_DATA )
    {
    if ( anActor->GetMapper()->GetArrayAccessMode() == VTK_GET_ARRAY_BY_ID )
      {
      pm->ColorByArrayComponent(anActor->GetMapper()->GetArrayId(),
                anActor->GetMapper()->GetArrayComponent());
      }
    else
      {
      pm->ColorByArrayComponent(anActor->GetMapper()->GetArrayName(),
                anActor->GetMapper()->GetArrayComponent());
      }
    }

Glad to finally give something back,
Chris
