img2scad [-b|–base=N] [-l|–log] < input_file
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.
