Releases

Errata for the book is available.

Release v1.0 corresponds to the code in the published book, with two corrections to Chapter 16:

Page 235, file ConcentricSquareMapping.cpp: The case "a == 0 && b == 0" is not handled and can result in division by 0; above line 3 add "if (b == 0) b = 1;"

Page 242, file PhongDistribution.cpp: Line 1 of the code at the top, change "1+s" to "2+s"
