66### Common
77 - Bug: Found a bug in book 3 source ` isotropic::scatter() ` method. Commented out, using default
88 (as it was previously). (#669 )
9- - Removed: now that the code handles ray-surface intersection from either side, we no longer need
10- the ` flip_face ` class, so we've deleted it from the text and from the code (#482 , #270 )
9+ - Delete: vestigial ` vec3::write_color() ` method (now in color.h)
10+ - Change: All images and figures renamed to follow more logical convention, using the following
11+ pattern: ` {fig,img}-<book>.<sequence>-<title>.<filetype> ` (#495 )
12+ - Change: ` main() ` function gets organized into image, world, camera, and render chunks
1113 - Change: Added header guards to the text of all three books whenever a new header file was
12- introduced
14+ introduced, consistent with source code (#645 )
15+ - New: Added constructors that take ` color ` arguments in addition to the constructors
16+ taking ` shared_ptr<texture> ` arguments, simplifying calling code. Applies to ` checker_texture ` ,
17+ ` constant_medium ` , ` diffuse_light ` , ` lambertian ` , and ` isotropic ` (#516 , #644 )
1318 - Change: Added ` override ` keywords throughout. This keyword marks a subclass method as one that
1419 is intended to override a superclass method. It makes the code a bit easier to understand, and
1520 ensures that your function is actually overriding the method you think it is. Which is good,
