I have a Samsung Note 10+. It has a ToF camera built-in. So I can take 3D images. It allows me to do cool “highlight the subject of the photo” tricks like making the subject full color, while making the background b&w. Or making the subject crystal clear while blurring the background. Very cool. Somewhat useless, but cool.
But, wait… Is it useless? I figure I should now be able to take a 3D image, extract the data, and have a perfect depth map for use with my 'forge, right? Anybody have a clue on how I might accomplish that?
There are a couple of ways, the most straight forward is Blender that now has an easier GUI for beginners. By using a blend texture you can have an image where the farthest back is black and the farthest forward is white and all grays in between. all you need do is hand it the 3d object and apply the texture. this is not easy to set up but once set up is barely minutes to get what you want.
Otherwise there are a number of bump and normal map specific applications
