Hide edges in 3d

I want to know how to hide the edges (triangles) in 3D.
How can I do it ?
Also, is there any way to activate antialasing ?

This is what it looks like now

Hello @Javi-r

Use the vtkPolyDataNormals filter.

It doesn’t work I get the same result

const reader = vtkSTLReader.newInstance();
await reader.parseAsArrayBuffer(arrayBuffer);

const normalsFilter = vtkPolyDataNormals.newInstance();
normalsFilter.setInputData(reader.getOutputData());

const vertebraMapper = vtkMapper.newInstance({ scalarVisibility: false });
vertebraMapper.setInputData(normalsFilter.getOutputData());
const vertebraActor = vtkActor.newInstance();
vertebraActor.setMapper(vertebraMapper);

Result after applying vtkPolyDataNormals vtk.js 32.9.1

maybe you have duplicated points in your mesh.
What reader did you use ?
