Wings 3D Development Forum

OK... glad to know it's been there since 1.3.1

I'll have to try it on my older machine (Tiger and Wings 1.1) - working from there to see how far I can go into the newer versions...

The same problem also occurred to my Mac mini.

My machine's Graphic chip is Intel iris.
It might be the problem occurs in Intel graphics chip.

Can someone fix this problem?

I tried to modify wings_render module for this problem avoid.
However it is a unofficial solution and isn't perfect.
It forced draw egdes,but side effects occurred on face/secondary selection.
A file can download from a following url. Please use if you're interested.

I tried to find a workaround for that last year, but I also got a side effect. (and, unfortunately I lost the code when my pen-drive was damaged )

I'll take a look on it and see if in the machine I have the Intel chip I can get the same issue as yours.

That’s a pity.
It is scary because storage device there are times when broken suddenly,isn't it?

By the way,about wireframe problem was progress to solution!
I was finally corrected the display with no side effects(for example z-fighting in seveal mode),a clue was simple!
In intel driver,It seem that probably polygon offset count way is differ from other driver.
Change 2 value and work fine!

Line186: polygonOffset(1), %% change 2 to 1 for fix
Line226: polygonOffset(0), %% change 1 to 0 for fix

I think that there is a side effect in other graphics driver.
then I've uploaded a new file.(Use for Intel GPU Mac only)

(Edit:15/9/10, for Wings3D 2.0 files are available.)

render_module_for_intel_ok_ver2.zip is archive.
Does it work in your environment?

We thought the same too. That's why dgud added the option to change that in the Preferences->Misc->Edges display problems?. But there the minor values is 1.0.

I played with many values and no one worked for the Intel graphic I have. So I changed my approach and got some good result, but not really a fix (left is regular render and right with the "fix" applied):

The are more details in this post.

I tested your code in a PC (i5) with a Intel HD Graphics and still have "my" edge problem:
but for these motherboard with Intel graphic card it goes away just by changing the camera view/zoom a little.
I'm going to try it in a old PC with XP and Intel. But, it seems that this problem related to Intel has no way to be completely fixed - even if we can find a solution it's not applicable to all PC platform.

Thank you for useful infomation,
I understood that the problem doesn't limit in specific OS and by more complex mechanism...
It might be necessary that a setting of relative offset adjustment of each display elements
( hilight -- selection -- edge(wire frame) -- solid ).

Preference > Misc > Workaround >Edge Offset
This feature seems to adjust an offset in the selection area.
There are some tests by my environment(see follow a screenshot).


An edge display offset ,It's interesting that an the offset is affected in Face Selection.
