I am a student.Recently I need to do three tests about POV. And I have done
three tests,but I do not know whether they are right.I beg a hot help me check.
Requirements:
1,Raytracing the scene using no illumination source and distinct color settings
for each object representing different materials results in an image which can
be converted to a materials map M(x,y) by simple classification of the red,green
and blue channel images produced by the raytracer.A sample is shown in Fig. 2 on
the left.
2,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). A sample is
shown in Fig. 2 center.
3,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.
I have done three tests.Beg somebody have a check .Besides,about the third
test,I could not find the option of turning off mutual shadowing between
objects.So the result is the same as test 2.I know something wrong with
test3.How can I modify my codes?Whether codes about tests meet above three
requirements?beg a hot .Great gratitude and best wishes!
