I am testing if we can improve the display of weight Group Data. My first goal was to display Weight data in Wireframe mode. Here are my proof of concept results. Before i create a differnetial, i would first like to know if the visual changes are appreciated or should be improved. So here are some screen shots. If you like i clean the program and add a differential for further discussion.

Default Show Weights in Edit Mode
This is the default display when "Show Weights" is enabled in the Mesh display Properties (Left side is current look, Right side is new look, click on image to zoom in):

Note: in the new version the wireframe is colorised. Hence it has become less apparent. I personally like this because i always found it a bit disturbing to see the wires in black.

However i am not at all satisfied with the vertices display. I would like to make them slightly bigger and want them to show up more clean. Right now it looks like the edge display "distorts" the vertex display a bit.

Show weights in Wireframe mode
The wireframe is colorised in the same way as in the first picture, but the faces are no longer shown:

I think this is an improvement over how it was before (no weights displayed in wireframe mode)

Hidden Wire Mode
I personally like this mode, because it gives me a clear visualisation about which verts are weighted:

Note that all i did was adding the colorising of the wireframe in edit mode. Everything else already exists in Blender so i only have shown how the colorised wireframe works with the existing display features.

I kindly request some feedback so i can step ahead :)
thanks

+1 for "Show Weights in WIreframe Mode". IMO, this works really nicely, and looks like something that could be really useful in a few situations.

I'm not so sure about what exactly "Hidden Wire Mode" is supposed to be doing though. Though, if it's just the same as "Show Weights in Wireframe" except that the front faces get culled, I guess there's no harm done.

1 for "Default Show Weights in Edit Mode". Sometimes I do actually want to see the topology to see how the weighting is lining up against it. The new display is a bit vague.

Weight is changed relatively to vertices .

Ideally, In Wireframe mode, unselected vertices should be colored, too.

And if we start to color elements according to weight values; we could think of different kind of weights.
Vertex Group Weight, Crease Weight, Bevel Weight, Goal Weight for Curves.

@JoshuaLeung:

The option "Hidden Wire" exists since a few Blender releases. I only showed how the weights would display when that option is enabled. btw i believe this option should be renamed "Hiden Face" to make it more clear what it does...
In the attached differential the "show weights" in Solid mode now displays the wireframe overlay again without colors.

@zeauro:

In the attached differential the unweighted verts are displayed in pink. I want to use the color TH_VERTEX_UNREFERENCED from the user preferences isntead, but i could not yet find a way to get access to that color.

Hidden Wire since 2.69:
http://wiki.blender.org/index.php/Dev:Ref/Release_Notes/2.69/Modeling

Usually, you would use the following:

To store the color in col
UI_GetThemeColor3ubv(TH_VERTEX_UNREFERENCED, col);

Or to set it directly
UI_ThemeColor(TH_VERTEX_UNREFERENCED);

But since this is in blenkernel, you may wanna check this code here:

source/blender/blenkernel/intern/action.c:256

From quick glance -- is it possible to make it so backface culling affects for wires as well. Would make more sense imo.

Summoning @ideasman42 and @brecht here.

This functionality is fine to add, I left feedback on D390, some changes should be made I think this patch could be included in Blender.

@Gaia, let me know if you're not interested to update the patch, and Ill check on making the changes I suggested.

I tried to modify D390, but could not get there. So i ended up with D585 for reviewing.
