    VP Open GL fixed in 2019

    Don't thank me. :-) I only did a small portion of it. It's really an effort from a great team.

    VW 2019 Display Bug when rotating 3D model

    @bpsabatier Those Marionette doors are definitely the problem. It is located further than our observable universe (1070 times further!!). We are trying to see how and why these Marionette objects are generated and corrupted. So for now, I would avoid using NanaWall doors. Also, one trick you can do to delete these doors is to select everything you want in the view and do an inverse selection. You will see it selects the doors located further away. Then you can execute "edit>clear" with those doors selected. Then you should be able to get the correct fly over back again.

    It's in our pipeline of fixing the bug right now. I will let you know when we have any definite answers ūüôā.

    Thanks for the reminder @zoomer. @bpsabatier has sent the file to us :-).

    VW 2019 Display Bug when rotating 3D model

    Hello @bpsabatier, If possible, could you attach the file here or send me through the message? We could inspect the file carefully and identify the problem. Thanks!! Chih-Pin
  6. You can see more multi-core usages almost anywhere, including those listed above, especially transiting from one view to another, entering/exiting editing modes, turning on hidden layers, changing view render mode, turning on multi-view, and now switching between sheet layers.

    Virtual Reality (VR) & (VRaugmented reality)

    I haven't done the experiments on this by myself. But this is another way to reduce motion sickness -- https://www.wired.com/2015/04/reduce-vr-sickness-just-add-virtual-nose/ But no matter what, I believe that motion sickness will still be there unless the headset has some optical magic implemented, something like this -- https://www.theverge.com/2017/12/20/16800474/magic-leap-one-creator-edition-augmented-reality-goggles-announce

    Multi View Panes Default to Split Vertically?

    @Pat Stanfordis correct. The ViewPane and splitter data are saved with the document. So you are able to save your templates with your preferred view pane configurations. But if you do not load from the template when creating a new file, it will create the default pane and splitter configurations. Chih-Pin
  9. Just for the record before we can provide the fix. If anyone runs into the similar issue in MultiView, please try turning on Unified View. This may solve some navigation issues (e.g. zooming) in perspective view with Unified View off.
  10. Hello line-weight, If possible, could you send the file to me so that I can take a look? Thank you so much!! Chih-Pin

    PIL (Python Image Library) for VW 2018

    Have you tried python -m pip install pillow? If successfully installed, you can see what version of pillow it tried to install.

    Hidden Line Rendering 20 min vs 3 Seconds

    Suggestion heard, I will raise discussions with my colleagues and bosses.

    Hidden Line Rendering 20 min vs 3 Seconds

    For instance, this is a fast HL mode on a cylinder - This is a standard HL rendering -- As you can see, the edges on both ends of the cylinder are missing in the fast HL rendering. There are also other similar cases to this. In my opinion, we need to at least make fast HL look the same (or at least similar) in these cases before we can make it as one of the render modes.

    Hidden Line Rendering 20 min vs 3 Seconds

    Sorry to disappoint you on this. But based on what I, as a software engineer, suffered when adding new features and fixing bugs in this complex system, I believe it's not possible to be that fast.

    Hidden Line Rendering 20 min vs 3 Seconds

    This is basically correct, except you will also see similar trick when you are flying over the views in design layer HL render mode. Without this trick, it can't achieve real-time interactive HL rendering. But after you finish flying over, it will try to calculate the full and standard HL render mode. I personally agree with these two suggestions. In many cases, the fast HL rendering is good enough, and it's much faster. However, I also see some improvements needed for fast HL rendering. I also suffered the unnecessarily long time HL rendering in my own personal projects. I will create a VE(s) and raise the discussions internally. Hopefully, we can have these features in VW.
