[Bf-committers] Multi-view branch UI proposal

[Dalai Felinto]

Some comments:

1) You are mixing up display modes (side-by-side, anaglyph, ..) with
view selector (left, right, ...). That's a bad design in my opinion.

2) The view modes (side-by-side, ...) "have to" be applied for the
whole screen. Right now you choice the 3D stereo display mode in user
preference because your 3D display is part of your workstation setup.
If you have a 3D display that take side-by-side you will use side-by
side with it all the time.

2.1) That said, I think (for the sake of flexibility) it's reasonable
to have 3D stereo mode per window. That should be set in the Info
Editor header though, not in viewport/render panels.

3) "Arguably, the fact [that] there are multiple views of a pass in an
EXR is only as interesting to the artists as that it contains R,G,B,A
channels."  (Peter Hillman, OpenEXR dev)

To show the Combined.left and Combined.right is not aligned with that.
And I can't see why you would want that (it makes the UI clumsy)

4) That said, to have an option to select the view you want to render
from a given RenderLayer node "MAY" work. The big problem here is that
if you want to compose multiple views at the same time you need to
have one scene dictating how many views (and which views) we are
rendering.

Right now we are doing something like:

for view in render.views:
  compose (view.name)

I think the benefits of being able to compose multiview natively still
beats the potential advantages of rendering individual views of a
RenderLayer.

5) The option of selecting the multiview camera to use in the viewport
is not a bad idea. In a way it's similar with what we have for the
Image Editor.

6) The option of selecting the views in the render panel may be
interesting. But I will restrict that to "left, right, view1, view2,
..., All". Again (see 1) no EXR, Anaglyph, ... here.

6.1) We could later implement an easy way to output side-by-side,
anaglyph, ... My original idea (nowhere implemented) in the Image
Editor you should even be able to select how to save the stereo image
(single view, all views [EXR], stereo [anaglyph, side-by-syde, ...]).


I'm really busy so I'm taking slow in the emails. I was actually
planning to reply to your other proposal email only after I was done
with the review changes proposed by Brecht. But feedback like yours
(specially when concise and well structured) is really welcome.

Cheers,
Dalai


Why not only change the view mode (side-by-side, ...) in the user p
 você está misturando forma de visualizar (side-by-side, ...) com que
view ver (left, right, ...)
e o image editor precisa de 3D tanto quanto o viewport
Que mais, acho que mostrar os passes 1 a 1 não faz sentido (acho que o
brecht já tinha argumentado a respeito)
Nas palavras das especificações do EXR:
"para o artista, o fato de que um passe tem multiplas views é tão
(ir)relevante quanto o fato de que tem R, G, B"
ou seja, a view faz parte do pass
Agora, acho interessante a idéia de ter um seletor de view no Render
panel e na viewport
