How to convert 2D BMP images to 3D STLs?

By GrabCAD Tutorials on 07 Mar 20:02 1 answer 0 comments

The basic principle is to take a regular 2D image (in BMP format) and translate the
image’s gray shades into a 3D height map (Figures 1 and 2). The two-dimensional
array (i.e. color) of each element is interpreted as a height value in order to store
information on the height of each point. For example; the white points are flat, the gray
points are higher and the black points are the highest.
