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

(Akche001) #1

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


(Akche001) #7

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


(Nathan 'jesterKing' Letwory) #8

Looks good indeed, you are on adrenalin :slight_smile:


(Akche001) #9

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


(Nathan 'jesterKing' Letwory) #10

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


(Akche001) #11

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:


(Steve Baer) #12

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.


(Akche001) #13

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.
