Display Comparision. Can curve and edge display quality be improved more?

Why MOI 3D curves and geometry look more clean as compared to Rhino V6? IN this case, the smoothness of curve and sharpness of corners. Same with grid display.

I see them about the same, if anything Rhino is sharper/cleaner (with a 4K display, so that might be cheating a bit).

Go to Tool>Options>View>OpenGL, and set your Antialiasing up to max available:

Yeah I already turned up antialiasing setting, I thought this might be an issue. Also tried to see if there is certain setting to turn up just curve and edge fineness. Yeah! 4k display is clearly tricking here.

I have a decent system here.

What does Rhino command _SystemInfo tell you it is using as display adapter? (just paste the contents of the command here).

For this bit I have logged a new YT item: RH-43733

Yes, I checked that too. Drivers are updated to latest available version.

Looks good indeed, you are on adrenalin :slight_smile:

Yeah Indeed. It appears so. :grinning: That’s why I could’t find possible reason for woolen thread like look of curves.

I have no further ideas at the moment, @stevebaer or @jeff probably have better ideas.

Thanks Nathan. I thought I might point out this on Serengeti. While using different interface from different CAD programs, I felt it naturally itchy to see jagged curve/edge display and I think that it can make a difference on interface. I’m hopeful that you guys will improve it before I buy 4k display. :slight_smile:

Maybe you don’t like the thickness? I can’t really tell. Try running the TestWireThicknessScale command in Rhino (this is a test command so you need to type the entire thing in). Enable this feature and play with the Scale factors.

Hi Steve! In options/display modes/shaded/Object/Curves, I changed curve width to 2 pixels. so, it’s little thick than default value. While comparing to MOI, I saw that MOI looks like adding anti-aliasing layer on top of viewport and curves look like in some graphic design application, for example adobe illustrator. It’s a subtle but enough difference to make the display look like mac in windows, even on low configuration machine. Meanwhile, I will play with TestWireThicknessScale. Thanks for your attention.
