Integration into SuperSlicer

[supermerill]

Bonjour

Someone requested integration of curvislicer into my fork (https://github.com/supermerill/SuperSlicer/issues/177), and I'm interested to test it.

From what I understand, it work in 3 steps:

• deform the stl, for a given layer height (curvislice_osqp)
• slicing the deformed stl by a slicer and output a gcode
• un-deform the gcode (uncurve) It's right?

What I want to achieve:

• the user put the initial stl into the slicer
• he hit slice
• the slicer call your deformer
• it slice the deformed object
• it call the uncurve to create the finale gcode.
• it present the result to the user via the gui.

I think a crude poc isn't hard to obtain.

The main problem is that an object is never sliced with a constant layer height (or you're lucky). How hard it is to change curvislicer to take that into account? In the worst case, each layer has its own height. Can i pass an array of height ?

note: i can re-wrote in french if needed.

Bonjour,

The 3 steps are indeed correct.

Good question regarding the varying layer height. In curvislicer we do assume a uniform slicing after deformation, since the deformation itself takes care of varying the layer height automatically (within specified bounds), with the purpose of following the top curved surfaces.

From the user perspective, only the height bounds should be provided (e.g. 0.1-0.3 mm), while the final slicing takes places at the fixed layer height after deformation (by convention the max). Changing the layer height for slicing could lead to collisions or curved layer thicknesses out of the min,max bounds.
