Bonsai Juniper 3D Image

Post#1 by Wallace » 21 May 2017, 22:51


Here's the Gimped Bonsai tree image.
It's a Red/Cyan 3D image.
So break out your Red/Cyan 3D Glassed to view.

Thanks Tin.
It's one of the first red/cyan anglophiles I ever made using GIMP.

This image was one of a number of 3D anaglyph images, which started the whole red/cyan anaglyph craze on DeviantArt.
Now there's a lot of activity, with this subject on DA.
However, before that there was nearly nothing about 2D to 3D conversions on DA.

Is there a procedure to do this, or a script?

I don't have G'Mic installed right now but I think G'Mic has something that does it you give it a depth map that you painted and it generates the 3D based on that depth map.

Of you can manually make one yourself by taking 2 photos aimed at the same spot from two different positions about 6 inches apart (if it's further apart the depth effect is greater). and use different color channels and compose a new image using those 2 photos and use 3D glasses to view them.

There are G"MIC filter, to help with this.
Such as in the image below.

However I like to do it all manually.

This entails creating a "Depth-Map" of the image and displacing the various,
Red, Green and Blue channels.
To end up with the 3D red/Cyan anoglaph.

Here is an example of a "Depth-Map", created for the "M-Falcon 3D Conversion".

Here is the 3D conversion image.

The white color in the depth-map represents close up objects, while the black represents far away objects.
The colors in between give the image it's depth.
Black representing the furthest away and white being the closest.

Unfortunately,
I need to use Photoshop to get the proper channel displacement.
However,
the 3D image can be refined in GIMP.

A simple tutorial on how a "Depth-Map is made in Photoshop can be seen using the link below.
This can also be done in Gimp, but with minimal results as compared to PS.
The following link, is how I got started making 2D to 3D conversions with GIMP.

Thank you for this Wallace, I also appreciate your honest evaluation, it helps relative beginners like me not to feel like a failure when I can't achieve the near impossible.
