New selection mode!!! - Ignore Occluded Vertices

Post by aphex » Tue Jul 29, 2003 11:57 pm

Hey all!

By popular demand, I've been working on a new selection mode... ignore occluded vertices! This is one area where I've felt Blender has been lacking for a long time... picking the wrong vertex and having to move your model just to see which vertex you need is quite annoying to say the least! ;)

It's probably 85% complete now, but I want to make it a "complete" feature - ie. with user pref settings, etc. Depending on how much I get done - and how quickly - you may find it in tuhopuu before it reaches the main bf tree.

Still, just wanted to give you all the news...

That's all. Comments are welcome! ;)

Cool, can't wait to see/try it! I've had my humongous share of problems with selecting the wrong vertex (and it will finally be solved, yay!)

the word occluded does not exist in a main English-Swedish dictionary...

and please tell me more in detail about this, for me it sounds not more easy than before...

is this backface culling?

if it is just a old feature with new thing: select-vertices-and-push-a-button-to-hide-them, then I am not very impressed...

I would rather see real backface culling...

ahemm... :?

ztonzy, as far as I can tell he's talking about not being able to select vertices that are hidden by faces. so it IS close to backface culling (aphex, since you got the algorithm, are you gonna do that too?)....perhaps it's even better because you can still see the entire model

This feature should be selectable, I tend to rotate the model
to get a sense of what is behind or in front, but sometimes there is a
need to select points inside the object, especially if working with multiple layers. I also tend to work in perspective not orthogonal views..
So features like this would be more a burden than utility..
I mean it sounds nice, but after working with it for a while
I'm sure more will probably not consider it very useful.. However it
would probably be good for vertex coloring and other things that need the functionality..

you don't like it you turn it off, easy right?

Occluded = hidden.

Basically, what Goofster said! ;)

Backface culling relates to how you actually draw the mesh. Culling should be easy enough to implement, but is that the required functionality? Solid mode does this for us already and, as Goofster mentioned, it is good to be able to view the entire mesh in wireframe views.

This is a valid point. It is perfectly possible to keep the existing functionality for all Ortho views and to use the new method for just Perspective views. It is also possible for wireframe views to continue using the original functionality, while shaded views benefit from the new code -- this is the way LW does it. Again, this can be a user preference thing.

It is my intention to address this topic on the funboard when the time comes, and, of course, any comments made here and on the list will be noted! ;)

Cheers,

That's what I meant by feature selectable..

yes, I know that's what you meant, but considering Aphex already mentioned it, I really don't know why you were ranting about it.

Great! really excellent!

about the culling discussion:
That would really be useful. Even in solid view those vertices are still visible... so getting rid of those "hidden" verts (as a toggle, an option) could be REALLY nice :)

and again: BRAVO!

hey aphex!

thanks for the screenshot last night, looks really nice!

but I have an idea for you, why not being able ALSO,
to view the edges/vertices straight through the shaded mesh for the frontside of the mesh, meaning that this new feature (yours) is showing the edges/vertices on the frontside, and at the same time the back of the model is hidden (as your feature works...)

is it a stupid idea? or a smart one...?

please let me know ;)

Sweet, sounds good. I would really like to see the edge line highlights more like Wings3d, 3ds max, and other highend modellers. I know blender kind of has edge line highlights but it doesn't look very good.
