I created an addon called JRemesh with that you can use Instant meshes for quad based remeshing (GitHub - jayanam/jremesh-tools: Blender addon for quad remeshing)
I will integrate Quadriflow as well and I saw that an operator is included in Blender that is called Quadriflow. Then I compared the results of this operator with the Quadriflow application and got huge differences. I digged a bit into the Blender code and found out that the operator is an own quad extraction algorithmn and doesnt use Quadriflow, is that correct?
I also wonder why the Quadriflow code is included in the Blender sources, when it is not used at all.
Thx and best
