Since Batch Files do not support floating point, the input parameters for drawing the sphere are limited to integers only. The ''k'' parameter has been hardcoded to 2. The <code>ambient</code> variable for this code is scaled up 10 times of its value in C implementation. For example, <code>ambient = 0.1</code> in C code corresponds to <code>ambient = 1</code> here.
Lastly, the variables used in calculations are scaled up 100 times of the actual values in C implementation, and then scaled down 100 times back for determination of shades.
