I have posted a test release for LDView 4.4 Beta 4 to GitHub:
https://github.com/tcobbs/ldview/release...v4.4_Beta4
This release mainly contains bug fixes since Beta 3, along with a few new features. The Mac version should work better on macOS Big Sur, and has an updated icon (as well as updated LDR and MPD icons on Big Sur).
One of the bug fixes with the most potential to introduce unexpected problems involves a change to the curve smoothing. It now does not try to smooth out two facets that are joined by both a conditional line and an edge line. This can happen (for example) when a curved primitive like a torus extends to the edge of a part. This happens on part 88293, which is the part that was included in the original bug report that caused me to fix the problem. I suspect that it happens in other parts also. I would greatly appreciate it if people would let me know if they see any regressions in LDView's curve smoothing.
Note: because of this new behavior, I expanded the angle over which curves can be smoothed. This improves (for example) the hair on the Bart Simpson minifig head, and probably improves other parts as well. However, it's possible that I went too far, and it will result in areas being smoothed that shouldn't be, so please be on the lookout for that as well.
The ChangeHistory.html file that is included in the release lists all of the changes since LDView 4.3. In the macOS version, ChangeHistory.html is in the dmg. In the Windows version, ChangeHistory.html gets installed to wherever you install LDView (C:\Program Files\LDView by default). I'm actually not sure where it goes in the Linux version. Please see my Alpha 6 announcement for a list of what I feel are the most important changes relative to LDView 4.3.
Please let me know about any problems you find. The preferred way to do that is with LDView's GitHub Issues tracker. However, if you do not want to create a GitHub account so that you can do that, you can reply to this message.
My hope is that this is the last beta release before an official LDView 4.4 release.
