Title: Is it possible to remove closer objects by means of a "near plane"
Post by: cytotox on May 01, 2013, 01:48:58 PM
Like with manually changing the far plane to remove unwanted background - is there something to remove objects in the foreground using a kind of "near plane" adjusting / clipping? Other image parameters should not be compromised / affected, as this option is supposed to help in conjunction with manually setting up a pair of stereo images using the sidestepping approach (where unwanted foreground objects may unexpectedly shift into view). Manually changing the Z-start parameter does evidently not produce the desired result...  :sad1:

Can anybody help?

I have had some success eliminating distracting things in the foreground of images by using the Z shift tool in the main window of MB3D.
Is the middle button on the bottom left of the screen, with the four arrows centered in it.
I used it by clicking on the button, then dragging down with the mouse on the image until the unit counter next to the button read 25, then I released the mouse button. I think this, in effect, pulls the image "closer" to you along the Z plane.
To see the results, you must render again.
By doing this repeatedly, I was able to finally get something out of the frame, and get a good image.
You might try that, and see if it will work for you.

Hi there, and thanks for the answer.

I think I will try and ask Jesse if it would be possible to have a checkbox for the "Cutting" Tab to define the cutting X-, Y- & Z-planes with respect to the camera - when checked, the Z-plane will cut the object always perpendicular to the direction of viewing.

I did this using cutting planes in this piece: http://cyanideclyde.deviantart.com/art/Escape-to-Infinity-372378015?q=gallery%3Acyanideclyde%2F43545516&qo=5 (http://cyanideclyde.deviantart.com/art/Escape-to-Infinity-372378015?q=gallery%3Acyanideclyde%2F43545516&qo=5)

I didn't remove the obstructing cubes, but decreased their opacity. Reducing their opacity to zero eliminates them, though.

I cut the objects(2 cubes) out of the view in multiple cutting stages and then made a composite final image in Photoshop. It was a fair amount of work but should work for you, if you don't mind the extra labor overhead.
