CHAPTER 2
Hard Shadows
2.1 What’s C overed in This Chapter
is chapter covers algorithms that generate hard shadows. e discussions
around each categorized approach include details of individual papers and details
on how to make each approach feasible in terms of image quality and performance.
e main categorized approaches include
● Fake shadows on planar receivers (Section 2.2) [7, 355].
● Shadow depth maps (Section 2.3) [7, 354, 507, 158].
● Shadow volumes (Section 2.4) [7, 355, 158].
● Ray tracing (Section 2.5) [613].
e chapter concludes with other miscellaneous hard shadow algorithms (Sec-
tion 2.6), followed by trends and analysis of the criteri ...
