Reported in https://github.com/prusa3d/PrusaSlicer/issues/2752 and was a result of setting support contact z distance to negative value.
This lowered the maximum allowed print_z of the next layer, even though previous layer had object layers too, so the penalty from the contact z should not have been applied.
Fixed simply by rejecting the negative contact_z.
when parsing localized file names by the PlaceholderParser:
UTF8 characters were handled as chars, and the negative char values were
used as indices into 7bit long tables.
used for Perl unit / integration tests only. With this commit,
the code will be cleaner, but likely the unit tests will not run
on Windows, if installed in a localized path.
When generating patterns which are less than a full wave, always
generate the last point correctly.
When extending a full wave to a line, fixup the last point
to the real gyroid position instead of shifting the point.
That could happen on empty support layers which do not necessarily matter, since their spacing is not generally synchronized with the object
The new hopefully correct logic is "if there are extrusions on a layer, check that last layer with extrusions is at most the new layer height below
This is a fixup of changes from 0de6e53 and 6ab1cec
for the GLVolumes before sending to the GPU driver. The following commits
were partially reverted:
4269c8b23c Removed GLVolume non-VBO rendering
d15698e21e GLVolume and GLIndexedVertexArray refactored to send data to gpu at the first render call
Namely, the GLVolume buffers are "shrink to size"'d before sending their
content to the OpenGL driver, and the vertex buffers are populated
as quickly as possible from the GLVolume, so that the same buffer is not
kept twice in RAM on systems, where the RAM is shared with the graphics
card.
Also the memory allocation reporting was improved for the GLVolumes.
Added detection of empty layers so the wipe tower doesn't trip on them (it is not printable anyway).
This should improve wipe tower reliability with supports, objects standing on edges, etc.
I also turned an assert into exception throw to prevent hard crashes and nonsense output.
