Question about Ex.2 Shading about cg HOT 5 CLOSED

You should show both a sphere and a parallelogram, it is sufficient to show either orthographic or perspective (it does not make a difference as the shading part is independent from the ray generation).

Is it okay to use the special case of the sphere centered at the origin for the shading section?

from cg.

Yes

But Professor, you didn't mention we need to implement both sphere and parallelogram in the assignment page or code. Some students read the issue a few hours before the due, some students still don't know. Could you please make the requirement a little more precise next time? Thank you very much.

Given the ambiguity, for the shading part it will be sufficient to have either the sphere or the parallelogram. The text was indeed not sufficiently clear.
