files produced with the pseudo-3d layer are supposed to be viewed/boardcasted through software. Any software with special 3d output can view the image and use the pseudo-3d data for special results. Hence some example: output view:
3d television; both old, current or future generation (3d glass or 3d glassless etc).
PC tablet that detect light source: so the software can "cast" virtual 3d shadow over the image giving the "feeling" of depth (hologram etc)

Additionally these files could be used as source as well (3d brushes)

i may have a problem, but i don't see the point of this feature ^^

I'm not a fan of the Zbrush approach with 3D object baked into a layer that keeps a depht map to include future object or paint on the top. This is a bit out of the scope and overkill in my opinion for a painting program. But but but. ....

... but  in another hand I know that a simple 'real time' bevel applied on brush strokes can save a lot of time during details ( especially if you can set the distance of the bevel , the opacity of it, the color of the shadow and the light ) . This make a 2D pass for micro sculpting textures very cool and time saving.
Thats one of the feature I miss from proprietary software, but I can work without as I did the 3 last years... I did tutorial about this technics, as it was something very specific to my workflow , here are some picture extracted from this 6 years old tutorials :

Well, obviously I lack algorithm/mathematical competence to refine this brainstorm. I know technologies like bump-mapping, emboss filter and lot of this stuff (often combined to achieve unique results) are old stuff.
But I was thinking to something which take directly advance of the last "3d fashion" we're thrust into today (which obviously is the next challenge for today artist). As 3d I don't mean just 3d animation but the whole stuff related to 3d output (again: glassless 3d tv, "nintendo 3ds" alike devices,  "holographic 3d" covers printing).
It's not just to have a Bas-relief .png file but more likely to give a complete artistic approach to "depth" drawing.
For example: combining a common semi-opaque layer with a pseudo-3d layer you could "draw" a cloud over your picture.. the capability of the output device will be able to deliver unique 3d feeling directly from the mind of the artist.
I think that zbrush is more of a tool for 3d modeler who need to add artistic feature while 3d is still load-bering (just hyptesis, I don't use/know/can afford Zbrush software); this approach is quite opposite (thus the same exact stuff at mirror)

From what you say alexandro, i feel like you are wanting a software that would be a mix of "3d software" and a "drawing software".
As a matter of fact, Zbrush allows you to create entire environnments with very artist friendly tools.

Here you can have an idea of how it works :

Is that looking more like what you had in mind ?

[Alessandro]

Zbrush is more about 3d model elaboration (painting and sculpturing). In what I am suggesting there are no model at all: just "aerial" brush strokes that can get "stored" in a layer.
Such brush strokes are "stored" in layer and are used to "paint" directly the image in the eyes of the viewer (as the individual who watch it). Zbrush rely mostly on 3d models; thus "the viewer" is indirectly affected by the show (giving him/her more with the possibility of move the camera as much they want)

Zbrush at the base was really oriented as a 2.5D program , with a canvas where you can throw pixel with a Z depht infos ( named the Pixol ; from the editor name Pixologic ) . Zbrush could create 2.5 painting who got a 3D look by using 3D model as painting brush , and with the ability to paint texture and material on the top.
What makes Zbrush famous in the 3D modeling world , was the possibility to customize the 'Brush' tip ; basically a 'real' 3D object and not only a 2.5D. The creator did a sort of sculpting mode very fast , to can sculpt a brush , then bake it on the Z canvas ; and paint the shader. The popularity of this feature growed when Zbrush could import and export a brush ; and most of artist started to abuse the Zbrush brush system to sculpt. Now most of poeple think Zbrush =  Sculpt 3D object , and the developpement of the software goes into this direction ...

I explain all of this , because I think your "pseudo 3D layer" concept is exactly what Zbrush is done at the origin ; the 2.5D with a depht pixel ( without having 3D object as brush ).

(ps: the video Pyo posted is about a 'brush creation'. Watch here http://www.youtube.com/watch?v=QxjNwoGlkFY , to see an artist using 3D model as brush and bake them on a Z canvas, and play with light , paint material....etc.... he use Zbrush as the program were designed at the base )

indeed, and realy bringing 2.5D into mypaint might soon bring the need for 3D brushes...  But Alessandro's request could perhaps be handled by another application that can import the mypaint files, and that does an eye dependent left-right shift of different layers for 3D display.  In other words: it assigns a different depth to a different layer.  No change in mypaint would be needed in this case, if this "post processing" is acceptable.

But a bumpmap layer might be a good idea for another purpose that is exactly within the intended scope of mypaint: it could be attached to the background, and used to simply modulate the alpha channel, so you would see more paint on the bumps of the canvas fibers.

photoshop's non destructive layer modifiers are quite useful in some cases. I tend to use outline, drop shadow and gradient overlay a lot.

I dont know if mypaint would ever go in that direction, but it would be useful to have these if it ever adopts the gegl library.

I personally would love to be able to use mypaint's backgrounds as a layer modifier and tweak them dynamically


to the original post> artrage has a similar approach to 3d in layers- depending on how much oil paint you use and its metalic value- you get to see a relief effect as you manipulate it on the canvas. Its other tools take advantage of that effect too. I've seen people on AR forum do some really interesting and creative things with it!

[Bollebib]

it might be just me but this seems like overkill to me for mypaint.

I'm sure it would be handy but does it conform with the direction of mypaint?


I would expect this more from Gimp....possibly


I'd rather have a texture brush in a case like this
bump layers are a bit limited in their usage

but on the other hand I would surely welcome it if it did get into mypaint
