rt - My ray tracer. Written in C++11. Using nothing more than STL.

Age	Commit message (Collapse)	Author
2022-04-20	Add vup (vector up), which controls the rotation of a camera (viewport). If ↵	Keuin
	vup is set to {0, 1, 0} (y=1), the camera should behave exactly the same as in previous versions.
2022-04-20	Assert screen and image are of the same aspect in aa_viewport::aa_viewport ↵	Keuin
	and basic_viewport::basic_viewport.
2022-04-20	Code refactor: make basic_viewport and aa_viewport no longer a child class. ↵	Keuin
	Move data into classes. Code refactor: make threading.h more specific, reducing redundant data copies in memory. Code refactor: make camera parameters more clear and well-defined in viewport.h, ready to extend camera flexibility.
2022-04-16	Move trace logging to tracelog.h.	Keuin
	Pixel-wise, comprehensive, beautiful trace logging.
2022-04-14	Make hitlist<T> no longer a generic class (but hitlist::color<T>(...) is now ↵	Keuin
	a generic member function).
2022-04-14	Remove viewport8b and basic_viewport8b.	Keuin

2022-04-13	Global diffuse lighting. (gamma not corrected)	Keuin
	Some operations on pixel<T>. Make ray3 support copy semantic. Fix vec3 operands does not filter out vec3-vec3 as parameters. random_uv_gen generating random unit vectors.
2022-04-13	Use basic_viewport8b if antialiasing is not enabled.	Keuin

2022-04-13	Antialiasing. (not parallelized)	Keuin

2022-04-13	Simplify bias_ctx's constructor.	Keuin

2022-04-13	Generalize hitlist and basic_viewport. (HDR in the future)	Keuin

2022-04-13	Rename viewport to basic_viewport.	Keuin
	Extract interface viewport.
2022-04-12	Refactor: move hitlist, object, sphere, viewport into single files.	Keuin
	Add bias_ctx for setting sub-pixel sampling bias.
