Requirements:
pov2,Raytracing the scene with all diffuse surface reflectances set to unity and
no
ambient reflectances resulted in a 8-bit shading image Shade(x,y).

pov3,Generate a POV image NoShade(x,y) with the option of turning off mutual
shadowing between objects. The shadow map (0 for shadow and 1 for illumination)

of NoShade(x,y) is shown in Fig.2 on the right.

This pov2.pov is the same as pov3.pov,and the only difference is pov3.pov
consider the shadow of the objects themselves,not consider the mutual shadow
between objects.pov3.But I have a confuse:the difference map which is the result
of test3 minus test2 should be 0 or 1.However my difference map contains other
values apart from 0 and 1.
I do this two tests in order to judge the difference map pixel is in shadow or
in light.I want the output images differential is either 0 or 1, but the results
are not only 0 and 1,and also contain other results.Obviously it is wrong.Maybe
something wrong in test3 about turning off mutual shadow between objects.My
codes have uploaded,I beg somebody help me have a look and resolve this
problem.Thank you!
