How to use "Merge" in GMSH ?
Hi,
I am new on GMSH and i want to realize a mesh based on a picture. My goal is to 1. import the picture in GMSH using "Merge", 2. generate a mesh based on the contrast in the picture (in fact the picture is binary) using "Plugin(ModifyComponents)" and finally 3. use the blossom-quad algorithm described in the paper [J.-F. Remacle and al.,Blossom-Quad: a non-uniform quadrilateral mesh generator using a minimum cost perfect matching algorithm (2010)]
The picture used is "crop_1_grad.png", my code is "code.geo" and the merged picture is "merged.png". So i want to be able to translate and resize the merged picture in order to make it fit in the bounding box at the lower right in "merged.png". You can see a zoom in "bounding_box.png". My constraint is that can't modify the geometry of that box. A. Please to you know a way to do that ? B. Please do you know how i can modify my code in order to use the blossom algorithm ? I tried something but i thing i am doing the wrong way
Thank you
