Blender 2.8 Wireframes Discussion


#128

Before:


and After:

I think it’s obvious that the wireframe visualization has worsened. If I didn’t work with blender for hours in wireframe mode I wouldn’t protest and wouldn’t say anything, but it’s a backward step and people like me who use wireframe modelling for many hours a day will notice it negatively. I’m not trying to be pessimistic or discourage anyone but this is the wireframe we have today. The lines of the colored axes appear to be above the object when this is not the case. And the lines that line up next to the grid are practically invisible.


#129

This is probably a bug

Wire frame has vastly improved in the last months, but I still feel selection should only work with what you can see. For instance, If you click in the middle of the default cube, where there are no wires visible, this should be like clicking in empty space. This is not the case right now and if you click a visible edge of a back ground object through another object, you will in fact select the background object, but click again in the same place, and the foreground object is selected. I have a feeling I know why this is happening right now, but I think a hack should be made so that clicking a face (which should be invisible in wireframe mode) should not select the object.

I don’t want to complain too much about this, because the software is pretty well usable right now and overall, I’m very happy with 2.80.


#131

This is one of my major gripes with the new wireframe… I’m used to clicking on wires behind other objects and selecting first the object which own said wire/edge, not the object in front first.


#132

For me, its a bug :smiley:

I love everything about 2.8 so far, except the wireframe mode. Its harder to read than 2.79.

Back in 2.79 to view wireframe I only needed to press 1 button, which was “Wireframe”. Now I have to press “Wireframe” + “Show whole scene transparent”.

When “Show whole scene transparent” is enabled, verts are almost invible in edit mode. See left side of attached image. HOWEVER, when I try to pan or rotate an object, verts become clear and visible ( like on right side of image but with xray on (because “Show whole scene transparent” is enabled - sorry I cant make screenshot while panning or rotating, but it looks). Is it just me or others experience this too?

Is it possible to keep verts clear in edit mode while no buttons are touched?

You can increase the vertex size in Theme settings 3D View if you want. This particular problem I don’t think is bad, the dithering is the real problem here.

I read @Hypersomniac stating that wireframe mode is actually a very complex shader even though it looks and sounds simple. The translucency is done with dithering because you can’t alpha-blend easily with so many different overlays already blended together.

When it comes to dithering, possibly the color of the wireframe could change to blend between viewport background color and actual wireframe / seethru-face color.

So the deeper something is in the model the more the color of it’s wireframe gets close to viewport background color. This could help with the dithering problem without need for alpha-blend.

I don’t know how complex this is to do from programmer’s perspective as opposed to dithering. I understand that with dithering many many transparent depths are possible but it’s impossible to read even after the first depth anyway.

Even caring about just single depth would be better than having everything dithered.

So if background is 0.250 dark grey and wireframe is 0.000 black the wireframe behind is 0.125 dark dark grey and faces blend with the same approach - a kind of very simple transparency.


#135

I feel the same. If i see the wire, and it is isolated without any other wire on top of it, i should be able to select the object whose edge i am clicking on, not the object that may be sitting “in front” of the one i wish to select in relationship to the view.


#137

We also need Wireframe option in the Workbench Render Engine panel.


#138

Hi. I use Blender for fixing models for 3d printing because it allows me to fix even the smallest errors (they must be closed geometry without non-manifold problems). So for these, I’m constantly switching between solid and wireframe mode while using the “Select Non Manifold” and the “View Selected (shortcut “.”)” options.

In this first built I found that it helps a lot to have this kind of 3D/deep feeling wireframe most of the time but it is also a lot of trouble when trying to see isolated selected vertices in high density models.

Here at the left is blender 2.79b, where you can easily see that there are 4 vertices selected; while at the right is 2.8 with also 4 vertices selected.

It’s almost impossible to find the selected vertices that are behind or within other high density meshes (forcing me to blindly keep drawing deselection boxes until I have left just a few vertices selected within a small area, and then been able to zoom in (pressing “.”) and actually seen some of the non-manifold vertices selected with “Select Non Manifold”) then repeating this blindly deselection process through all the model.

Is there a way the old solid wireframe view could be enabled as a wireframe mode? maybe an option where the selected vertex could be rendered over the 3D wireframe, or something like toggling off X-ray looks now but, instead of only showing the visible geometry, rendering all the hidden geometry as well.


#139

While I must admit it is not convenient, it’s not simple to fix.

So as a workaround I suggest to

  • select non-manifold
  • increase selection (ctrl + Numpad ‘+’)
  • invert selection
  • hide selected
  • select non-manifold again

Now you have the problematic areas to work on with a bit of context.


#140

The facedot is draw outside the faces in an object with subdivision.


#141

isn’t this food for papercut?


#142

mmm, maybe, but I don’t think so. Papercut is about UI and this thread is about wireframe and @Hypersomniac is here, I don’t think that he enter a lot in the other thread. But could be.


#143

Other feedback about wireframe, actually the grid is draw over the wireframe. For example, if we have a model over the grid we see the grid and it appear that the model is underground.


#144

Yes, I think for most of the cases that should work. Thank you!
