Get the greyscale image from the net or create your own greyscale image by 3D software.


Remark :

Greyscale image is not really a black and white photo.

It is in fact a file records the X, Y and Z values of an object.

The cutting depth depends on the brightness of the image.

Step 2: Compress the Height of the Image to About 77% of Original
