I have tested TestSquishPhysicalStrain and TestSquishGeometricalStretch in August 25 but I did not see any effect after choosing different settings in the options. I also did not notice any differences between Squish in Rhino8 and Wip9. Has there been any development of the new squish algorithms s…

[image] Rhino WIP Feature: Two new algorithms for Squish Serengeti (Rhino WIP) We’re introducing two new algorithms for the _Squish command that offer more control and robustness compared to the original implementation. Like before, these methods flatten a 3D m…

The Squish command itself has not changed its algorithms in the WIP. TestSquishPhysicalStrain and TestSquishGeometricalStretch are currently the only way to access the new algorithms in the WIP. At this point I’m fairly certain these new algorithms will not make it into Squish in the commercial rel…

Hi Pierre, Thanks for your reply. I will do some tests tomorrow and let you know about the results. I did have a quick look at remap, works quite fast and looks good, but I did not see much effect after changing some parameters. But I will give a more extensive report tomorrow. Erik

I have compared the different methods of flattening with different settings, and compared the results with a handmade flattening of the physical last, using the “wrinkled paper method”. There are large differences between my handmade result and the digital flattening of the scanned last. I realize…

[image] Erik Hondebrink: I realize that different shoemakers will have different results when flattening lasts, and you always have to correct manually to get a good fit of the upper on the last. Every shoemaker has his own method to adjust when drawing the patterns, and that method of adjusting…

Hi Erik, When cutting the scanned mesh, make sure to cut it cleanly and precisely first — feather line, heel and toe splits — so you get clean, accurate edges before running QuadRemesh. If the mesh is not cut correctly before QuadRemesh, the edges will be messy and Squish will not flatten accuratel…

Once you have your Squish result, print it out and hold it against your physical last to verify accuracy — do not compare it to a paper flattening. For a correct paper reference: do NOT cut the paper when wrapping the last. Instead, hold the paper firmly against the last and simply mark the centre …

@Samir_Dzelic1 I always keep clean edges before applying Squish. When I make a paper flattening I minimize the cuts in the paper, ideally the cuts are only made in the excessive paper that crosses the middle line. In the picture you show a paper flattening that has no cuts and no wrinkles. How do…

I tried to test Botcha, but somehow I did not follow the right procedure when trying to flatten a (mesh) last and it failed. The Botcha component in GH to unwrap one half of a last gives me the same result as the Squisher component with the absolute limit set to 0 and all constants set to 1. The S…

Hi Eric! Thanks for testing our tool botcha. Here I tried to flatten your surfaces and here are some insights. The initial scans are kinda bad meshes, even after welding it I had to repair them to get anything to work. Ideally you would have a better scan quality with a full last and use the Shrink…

Serengeti (Rhino BETA)

seems like @pierrec is the person to ask.

share a .3dm file and the current vs. the desired result would be helpful i guess…

cheers - tom
