Feature idea: alternative object drawing modes

[gdevenyi]

brain-view2 offered the following draw modes for objects

• solid (default)
• wireframe
• wireframe overlay (useful)
• points
• hidden line
• bounding box

Wireframe overlay is useful for examining the underlying object structure

I'm not sure if it's the same, but Display does have a sort of wireframe mode ("3D Render" -> "Mode: Shaded" vs. "Mode: Wireframe"). Does that help?

[gdevenyi]

Ah yes, that's very close, that checks off "wireframe" on the list above.

The really great feature about "wireframe overlay" is that the wireframe is shown on top of the shaded model in a different colour. See attached.

@gdevenyi Check out the latest bicgl (rdv-new-opengl branch) and Display (develop branch). I extended the "3D Render / Mode:" command to include point and wireframe overlay mode. Let me know if this is useful.

[gdevenyi]

Looks nice? Thanks @rdvincent , is there a reason for the different lines being drawn in different dash types? That causes some anti-aliasing issues at low magnification

[rdvincent]

The dashes are actually something of a mystery. Probably an artefact of the rendering process somewhere deep in OpenGL. I am still playing with this so perhaps I'll find a way to prevent it.

[gdevenyi]

Alright, doesn't matter, my main use of this is to isolate specified vertices, and this works perfectly.

[gdevenyi]

Completely fixed in develop, thanks @rdvincent !
