Creating a relief in a surface from image

Hi All,

Been a while since I've posted here and looking for some advice.

I have been playing around with the image sampler to get relief in a suface based on saturation from an image.

Ie I am taking a B&W image, then trying to map it onto a surface where the darkest areas depress the surface 1" and the lighter areas less while a pure white area of the image keeps the surface at its original location.

So if I have a radial gradient, dark in the center, I would get a crater form. Or if I had a smiley face, I would get depressions at the eyes and mouth.

Although I have had some success with a script, the results aren't ideal. I looked around and did not find a script for this purpose on the forums although I am sure someone has probably already made one.

Will post some images when I am home. I appreciate any help you may have to offer!

Thanks!

-Andrew

create a grid of points and replace the Z value of these points with values from the image sampler. Make a surface from these points. You can fiddle with the size of the grid (the sampling resolution) and with the depth/height using domain remap.
