Topic: Question for the multifocus plugin

Hello,
i guess the output of the depth map from the multifocus plugin is 8bit?
is it also possible to get a 16bit depth map?

(and is this 16Bit depth usable in the 3D-from-depthmap-plugin?)

Re: Question for the multifocus plugin

As far as I remember the depth map is 32-bit floating point, and it can be used as such when generating a 3D model

Re: Question for the multifocus plugin

ok that sounds really good :-)
i didn't tried it yet becuse i have to finish my macro-focus-rail for my DSLR,
i will write soon i get results.

Now i know why i was not able to "paint" a detph map for the 3D-Plugin, i tried it as 8bit greyscale :-)
How is it possible to draw/paint a map in this 32bit format?

Hello Michael,

is it possible that you make a option to select the Bit detph for the 3D-Plugin map?
(to switch between 8 Bit & 32 Bit, (and maybe 16 bit))

I had some ideas to "paint" the death map, but this works only with 8bit.

Re: Question for the multifocus plugin

Do you mean the input depth map? You can already use an 8-bit grayscale image as input

Yes, i tried to figure out how the dethmap works.
I used a 8bit greyscale, and wanted to build shapes.
I painted a greyscale gradient (0-255) but i got some strange results.
Later i got the info from you that the input precision is 32-Bit,
so i thought this behavior is the result of the wrong input format from y image.

I mean the Plugin "3D Model" -> Generate from deth map

When a programm expects a 32 Bit input, it doesnt work with 8 Bit or is this incorrect?

The input can be both 8-bit and 32-bit.
If you give it a 0-255 gradient I would expect to create a wedge in 3D.
