Hi, you need to add additional modules to constraint the decimation. For example you can use the normal deviation mod to avoid flips or use the aspect ratio module to keep the triangles aspect ratio in a certain range. Regards, Jan Möbius On 3/7/23 00:25, nickexists23@gmail.com wrote:

I have been having a very hard time getting usable results from the decimator tool and am wondering what I am doing wrong.

I have mostly been looking at using the "ModQuadricT". However it seems that any usage of non-binary ModQuadricT with `decimate` like shown here (https://www.graphics.rwth-aachen.de/media/openmesh_static/Documentations/Ope...) will completely remove almost all vertices since the non-binary version has `max_err_` set to DBL_MAX. I instead have to use `decimate_to`. However, even with decimate_to the end result has many overlapping triangles while the original mesh had none.

Is there a recommended way of using this tool? _______________________________________________ OpenMesh mailing list -- openmesh@lists.rwth-aachen.de To unsubscribe send an email to openmesh-leave@lists.rwth-aachen.de https://lists.rwth-aachen.de/postorius/lists/openmesh.lists.rwth-aachen.de
