Your mesh is in only triangle lines. My program colors inside the triangle, I need to show only vertexes, I mean empty triangles. Just as the photos you shared above, I could not achieve same
I achieved that by setting
material.getAdditionalRenderState().setWireframe(true);

You are the savior of the day !I’m interested in how to keep the boundary of my model and reduce the number of meshes. I don’t see how he knows that an edge is a boundary, why all the edges of my model are judged to be boundaries, resulting in no mesh simplification
@collin:
Is your mesh indexed to eliminate duplicate vertices?
Any mesh algorithm that deals with shared edges will probably want an indexed mesh.

Hello, thank you very much for your answer! Yes, my grid index is to eliminate duplicated vertices, and I’m using the GLTF model, which is stitched together from a number of panels, and I want to eliminate excess triangular meshes on the panels, but using this algorithm will create some holes, I think is not open the reserve boundary switch, I do not know if this algorithm can deal with a lot of triangular mesh plane plate, and keep the shape of the plate
