Graphic bugs in rhino 6

(Riccardo Majewski) #1

Hi all.
I have some graphic bug in rhino 6, in last service release as same as in last service release candidate.

Lines, like grid, curves or edges are everywhere “1.1x wider than normal”, so they not appear correctly thin as they should.
The normal wireframe rendering i’m used to is that every cuve is just 1 pixel wide (with AA off), here in RH6 i have almost every curve displayed somehow “dirty”.
Also i’ve found the “Focal blur” menu is blurred! … how ironic XD
See attached .gif to understand.
If I active GPU tessellation the problem is somehow more evident, or the same.

Here is my system info:

I don’t know if it matter, my cpu is ryzen 1800x.

Just bought licence… hoping in a fix.

Thanks everybody for the support.

I can’t edit the main post because i get an error “The tag “unhandled” may only be removed by staff.”
Sorry for the bad layout…

Here is the difference in curve rendering.
See how RH5 is exactly 1 pixel wide… like, an absolute minimal perimeter needed to “contain” the bucket command in paint… in the RH6 version there are more, ugly and unneeded pixels.

You have no anti-aliasing enabled. You probably need to go into Tools > Options > Views > OpenGL and set some anti-aliasing.

(Riccardo Majewski) #5

As you can see in the .png it is not antialiasing because its not grey-scale pixels, those are completely black(0,0,0).
Antialiasing is disabled in both RH5 and RH6, as I want it to be.

( I can’t work properly with AA on, I’ll lose a lot of useful details. In fact i think AA for cad is just dumb… but more generally, AA is a smoothing that fakes the shapes, i prefer to see original clean and sharp shapes. )

In RH5 wireframe mode render curves/edges/grid flawlessly with AA off.

EDIT: i didn’t explain well what happen in the .gif. Other than that “dirty” curves rendering, the axes and the grid line at 0 (horizontal to view) change it thickness ±1 pixel, its not an error of the .gif, sometimes it really go 2x (the axys) or disappear (the grid).

EDIT 2: also the “Make 2D” form/window have all elements blurred out as the “Focus Blur” shown in the .gif .

EDIT 3: also the selection window
The problem is only for horizontal lines. It’s like the pixel are not rendered 1:1 but something like 1:1.001 .
RH5 is fine in this matter too.

Edit 4: it happens in both, horizontal and vertical lines (just horizontal for the selection window tough).
Here i’m just zooming out:
Orthogonal lines should never be 2pixel wide…
(I tried and, even with AA on the effect is washed away somehow, but still visible)

The fastest way to see if the problem i’m having occur is to see if a circle is “clean” or not.

Sorry for the spam, I hope it helps.

Up? Any hope?
In wireframe mode i can set windows pipeline instead of openGL and that fix the problem, but i cant set the same for all the other modes.

Up again?

I’ve logged it under RH-46636.

At every update i hope it’s fixed, working with AA on make everything blurred, feels like… “imprecision” everywhere. And even AA can’t hide the problem, actually it make it randomly worse for orthogonal lines:

Any news for this?
