FAQs / Re: Using Bitmaps for 3D

Hi Joe,
What you are describing here:-
Is exactly the technique that packages like 'Bmp2CNC' or even 'Mach1filter.exe' use to create their depth maps which, incidentally are the same type of files which are used in reverse for milling lithophanes.
For example - This was done with Bmp2CNC from a grayscale image.
Mesh is entirely different and can take you into the realms of .stl files and true 3D work which is in no way related to gray scale images.
For example - This was done with DeskProto from an .stl file.
Point cloud techniques are again quite different and are more akin to half tone than gray scale.
Each technique has it's own advantage and disadvantage and no one technique can be used to best advantage for everything you are likely to want to produce.
Hope this helps,
Tweakie.

The software, in the machine, reduces the color image down to a gray scale, with the limit of 250 shades. Then carves from that.
As Doug described it to me, the dark shades carve the deepest.
