Improve ExtrusionLine::simplify, eliminating many very-short extrusion segments which led to blemishes in thin-wall models sliced with Arachne #3014

sethml · 2023-12-05T20:47:25Z

This change makes ExtrusionLine::simplify() able to remove more very-short segments, which arachne seems to tend to produce frequently on thin-walled models with curvature. Interestingly, Cura does not seem to have this problem. From what I can see, when Arachne was ported over from Cura, a significant amount of logic was added to polyline simplification, but some of that logic was flawed. In particular, the simplification code in Cura seems to be in PolygonRef::simplify(), but during porting logic was added to avoid removing a point prior to a long segment and instead replace the two prior points with the intersection of the prior and next segments, but only if that intersection does not move the points too much. Unfortunately that test compared the intersection to the point at the other end of the long segment, thus the length test would always fail and the point would never be removed.

I made the following changes:

When considering replacing two points with the intersection of the adjoining segments, test the distance between the intersection and the two points prev and current, rather than prev and next. This change removes most extrusion blemishes around the perimeter.
For a closed polygon, allow removing the first/last point (which are the same). This can remove a single extrusion blemish per perimeter. In order to do so, we consider removing the last point, and pull the next and next_next points from the second and third points of the newly-filtered path.

While working with this code I noticed a few potential issues/future improvements:

As points are removed or replaced, their width is not updated. In most cases this probably results in negligible errors. However, I could imagine that if a point is removed between two nearly-collinear long segments and the segments have different widths, significant error could be introduced. Consider either not merging segments with significant width differences, and/or updating widths with a length-weighted average when merging segments.
Why is arachne generating so many nearly-zero-length segments in the first place? Consider changing it to no longer do so. Given that the nearly-zero-length segments seem to have a slightly different width than neighboring segments, I suspect that whatever heuristics arachne uses to determine width are generating these.
The logic in ExtrusionLine::simplify is pretty complex and challenging to reason about. Perhaps going back to simpler simplification logic such as Cura uses would produce more consistent results.

I believe this fixes #2840. Here's a photo of the model from that issue with this change:

… on thin walls.

src/libslic3r/Arachne/utils/ExtrusionLine.cpp

                Point intersection_point;
                bool has_intersection = Line(previous_previous.p, previous.p).intersection_infinite(Line(current.p, next.p), &intersection_point);
                if (!has_intersection
                    || Line::distance_to_infinite_squared(intersection_point, previous.p, current.p) > double(allowed_error_distance_squared)
                    || (intersection_point - previous.p).cast<int64_t>().squaredNorm() > smallest_line_segment_squared  // The intersection point is way too far from the 'previous'
-                    || (intersection_point - next.p).cast<int64_t>().squaredNorm() > smallest_line_segment_squared)     // and 'next' points, so it shouldn't replace 'current'
+                    || (intersection_point - current.p).cast<int64_t>().squaredNorm() > smallest_line_segment_squared)  // and 'current' points, so it shouldn't replace 'current'


This change makes sense to me.

it looks like the closed loop is still causing troubles:

Can you provide your .3mf for that?

There are still cases when the intersection distance test on line 139 decides not to discard points and leaves short segments, just many fewer than before. I could investigate more under what conditions that happens and see if we can fix them.

I'm using the project you attached.Sphere-Shell.3mf.zip
At layer 60. It looks like a edge case where the first line segment is tiny segment.

Oh, oops, I confused myself about which .3mf I uploaded with the bug report!

Hmm, I ran this with some debugging output, and I see the tiny segment in the gcode for layer 60, but the perimeter data for the layer doesn't seem to contain it. Here's my debugging data for layer 60:

For each point 'len' is the distance to the previous point. The first point just says 'len 0' since there is no previous point. In any case, I see no tiny segment on this perimeter, so I suspect it comes from some later processing stage. It probably does make the seam slightly worse on that layer.

it looks like the closed loop is still causing troubles:

Can you provide your .3mf for that?
There are still cases when the intersection distance test on line 139 decides not to discard points and leaves short segments, just many fewer than before. I could investigate more under what conditions that happens and see if we can fix them.

I'm using the project you attached.Sphere-Shell.3mf.zip

Oh, oops, I confused myself about which .3mf I uploaded with the bug report!

At layer 60. It looks like a edge case where the first line segment is tiny segment.

Hmm, I ran this with some debugging output, and I see the tiny segment in the gcode for layer 60, but the perimeter data for the layer doesn't seem to contain it. Here's my debugging data for layer 60:

For each point 'len' is the distance to the previous point. The first point just says 'len 0' since there is no previous point. In any case, I see no tiny segment on this perimeter, so I suspect it comes from some later processing stage. It probably does make the seam slightly worse on that layer.

I agree.
Looks like this is a unrelated issue

SoftFever

Looks good.
Thank you very much

Hi @sethml
Just a quick heads up.
I have temporarily reverted this change due to multiple reported crashes caused by the changes.
A brief investigation indicates that the issue arose because, after simplification, a loop was degraded to a single line.

These messages are now, sent to the printago websocket. The dialogs are not shown. For instances where ShowModal() was used to open the dialog, I return the most falsy one. The buttons are dynamic, but from a fixed set. We send back to caller whatever is availabe in the dialog, in this order: ["Cancel", "No", "OK", "Yes"]. These message are more like notifications. They are feedback more than they are anything for the user to action. Separately, there are the classes that derive from the parent class of MsgDialog. Most we can ignore: InputIpAddressDialog - sending to printer error, cancels blocking job UpdateVersionDialog - lambda that creates it was previously commented. SecondaryCheckDialog - "Are you sure" messages, cancels blocking job ConfirmBeforeSendDialog - slicing error messages, cancels blocking job. ReleaseNoteDialog - called in one place, commented out. UpdatePluginDialog - called once at startup; commented out. * Squashed commit of the following: commit ca3b071 Author: PilotMatt <[email protected]> Date: Mon Feb 26 12:29:40 2024 -0500 override tested and funcitonign commit a79dcfe Author: PilotMatt <[email protected]> Date: Mon Feb 26 00:25:34 2024 -0500 working commit a857816 Author: PilotMatt <[email protected]> Date: Sun Feb 25 00:12:26 2024 -0500 done download the configs you pass. If there's a override file, open both into json objects, and replace the values in the override value for all keys, except those excluded. for layer-height fields, we open the printer config, read the min/max and clamp the override value as needed. if the printer config doens't specify the max layer height (=0), then the max_layer_height is 75% of the nozzle_diameter. save the merged config file with a new file name. update the filename to pooint to the merged one. load configs into Orca as previously. commit 84db29b Author: PilotMatt <[email protected]> Date: Sat Feb 24 23:41:43 2024 -0500 cvhanges * status/sync_profiles command complete.
