strahl0's Introduction

strahl0

A raytracer designed after Peter Shirleys Raytracer in a Weekend.

Notes Book 1

This raytracer differs from the one in the book in some ways. I use C++11 in the makefile, and in the stochastics.hpp header, really everything else is just plain boring C++98.

The dielectric material has fixes and A LOT of comments to describe the code and why it looks like it does.
the quadratic equation for the sphere is a bit different, mostly in aesthetics: x^2 + px + q is the form I prefer.
My vec3 is templated.
Metal has a refractive index-field, for cheapo grazing angle color effects.
There's a plane class (there is one in the second book I think).
stochastics.hpp substitutes drand48 in the book for a C++11 std object.
hitable_list uses a std::vector.
I use a more accurate gamma_correct for SRGB, but I really should use the one that avoids problem close to 0.
Some fields and variables have different names here and there.

Note that the DOF chapter (the last) is not implemented.

Notes Book 2

No motion blur support although the interfaces are there.
color is used in most places where a color is expected as a result, color is just typedefed to vec3 though.
xy_rect etc. all substituted with a single templated aa_rectangle class, for example: aa_rectangle<X_AXIS, Y_AXIS>. This uses C++11 features to work out the complement set of {axis1, axis2}.
Image textures are implemented, but not noise textures.
bvh_node class is a bit different, builds a bvh from a hitable list in a static function instead.
Volumes and instances not implemented
