Request: Backface culling

Post by bryantrueno »

When I was modeling a creature, it was really hard for me to pick the vertex in front, half the time i select vertices that are on the back. It would be nice if Blender have backface culling. I also heard that it speeds up the 3d view.

backface culling wouldn't be enough [your object isn't guarnteed to be convex, so you could select a front-facing vert on another part of the mesh]

that said, it was or is in tuhopuu, and you aren't the only one that wants it

I'm surpized you didn't notice the other threads on the topic
sorta, the search function returns nothing on both "backface" or "culling"

ya but the thing in tuhopuu is not real backface culling in the way that it is just a feature that just happens and makes the view of the mesh nice and clean.

That doesn't mean anything?!

Yes it does. The Tuhopuu feature is half of it, now all it needs left is to auto hide all of the vertices behind the view of the front mesh

Now, that's understandable. What you wrote before just sounded like gibberish.

Funny thing: I was just looking for a feature like that during rendering. I'd like to render a wireframe head with it's nackside occluded. It's not possible yet, is it?

Not to mention how useful this would be for modelling. Definitely something to consider.

what color would that other part be?

because you can do it with two materials, one wire with a zoffset, the other either a solid black [if that is what you want], or perhaps grey or whatever [so the wire is on top of the solid mesh]

somehow I think a "hidden line" [that is what xsi calls it] mode in blender wouldn't be as useful as solid with wire for modeling

This wouldn't work as I still want other objects to be visible through the wireframe.

I think a hidden line view would come in handy quite often. What we are really talking about here seems to be two things:

1, Backface culling for selections

2, Backface culling for the view

I think these should be independant things. You should be able to select only frontface vertices in regular wireframe view and backface vertices in Hidden Line mode.

I see 1 best implemented as a toggle option in the Select menu and 2 best implemented as a new mode in the View Mode selector.

And 3, Backface removal during wire renders.
