Is it possible to have different edgeColor and color on circleSource ?

Hi all,

I’m trying to colorize an actor whose mapper’s input connection is the output port of a circle source:

        var c = vtkCircleSource.newInstance();
        c.setLines(true);
        c.setFace(true);
        c.setResolution(80)
        c.setRadius(0.00005);

        const mapper = vtkMapper.newInstance();
        mapper.setInputConnection(c.getOutputPort());
        const actor = vtkActor.newInstance();
        actor.getProperty().setColor(1, 1, 1);

So far, so good.

But:

actor.getProperty().setEdgeColor(1, 0, 0);

doesn’t work.

actor.getProperty().setLineWidth(3);

doesn’t work either.

The question is then: is it possible to have at the same time different edge and face colors on actors build from circleSource?

In a different use case, the color is obtained from a lookup table:

        var lookupTable = vtkColorTransferFunction.newInstance();
        const preset = vtkColorMaps.getPresetByName("rainbow");
        lookupTable.applyColorMap(preset);
        lookupTable.setMappingRange(0, 100);
        lookupTable.updateRange();

        actor.getMapper().setScalarModeToUseCellData();
        actor.getMapper().setScalarRange(0, 100);
        actor.getMapper().setLookupTable(lookupTable);

        let d = vtkDataArray.newInstance({
            name: "t",
            dataType: 'Float32Array',
            values: Array.from({ length: c.getOutputData().getPolys().getNumberOfCells() }, (v, i) => t)
        });

        let attr = vtkDataSetAttributes.newInstance();
        attr.setScalars(d);
        attr.setActiveScalars("t");
        c.getOutputData().setCellData(attr);

This was working well on spheres but is rendered differently with circle:

So here only the edge is drawn and colored. Is that expected?

Thanks for your help
