img2scad - Convert images to OpenSCAD structures
<https://gitlab.com/engmark/img2scad>
Default syntax:
img2scad [-b|--base=N] [-l|--log] < input_file
Description:
For each pixel in the input, it will create a cube in the output. The height of
the cube corresponds to the whiteness of the corresponding pixel.
If -b or --base is specified, all values will be shifted by that value. This
can be positive or negative. This can be used to output zero values.
If -l or --log is specified, the logarithm of the grey values will be used for the output.
Examples:
img2scad < example.png > example.scad
Convert example.png to example.scad.
img2scad -b 1 < example.png > example.scad
Convert example.png to example.scad, with a "bedrock" of height 1.
img2scad -b 2 -l < example.png > example.scad
Convert example.png to example.scad, taking the logarithm for the height
and preserving the black pixels.
