[Bug] about vtkClipClosedSurface

[jinjilynn]

Bug description

When clipping a closed surface generated from a cylinder source along the X-axis, the surfaces along x-axis are not properly filled. However, clipping along the Y-axis or Z-axis works as expected.

Steps to reproduce

const cylinderSource = vtkCylinderSource.newInstance({
  height: 50,
  radius: 10,
  resolution: 100,
});

const planes = [];
const plane1 = vtkPlane.newInstance({
  origin: [1, 0, 0],
  normal: [-1, 0, 0],
});
planes.push(plane1);
const plane2 = vtkPlane.newInstance({
  origin: [-1, 0, 0],
  normal: [1, 0, 0],
});
planes.push(plane2);

Detailed Behavior

No response

Expected Behavior

filling all the surfaces

I do not have "free" time to investigate and fix that problem (let me know if you have funding). Here are some ideas to investigate the problem:

• Does it work with just 1 plane in X ?
• Does it work when you cut a cube and not a cylinder ?

If so, an investigation could be to run the filter with breakpoint and step by step see how it behaves differently depending on the plane normal orientation.
