Alexandre showed me how to do with two or three steps, but I do not find them anymore.
The input DTM I use is stored as the one from onf plugin step “Create plugin” internally as a CT_Image2D. I want to produce somehow a triangluated mesh from this CT_Image2D to export with
“Export” >> “Meshes” >> “Meshs, format OBJ” (plugin base).
If somebody knows maybe he could upload a minimal script maybe purely with ONF, base and toolkit steps?
