v0.3.0

Major changes to the API have been made regarding material and vector3::reflection.

Overview

Full Changelog: https://github.com/BardoBard/Bardrix/compare/v0.2.3...v0.3.0

The changes have backward compatibility issues (compared to v0.2.x), only if you were using material class
or vector3::reflection.

Documentation Changes

Updated Bardrix_Reference to include material and vector3::reflection updates.
Updated Mathematics to include the correct vector3::reflection formula.
Added readme to Docs/.
Added sphere normal calculation example
to Raytracing readme.
Added documentation to sphere class
in sphere example.
Made sure that in Release Notes the links are to the versions they are referring to instead of the latest version.
Added
documentation Raytracing-Reflections.
Solved issue 33, where degenerate cases aren't marked as such.

Code Changes

Major Changes

Updated shininess in material to
have a limit between [1, infinity)] which for some reason wasn't the case.
Updated diffuse and specular to not be opposites anymore because I thought they were, but they are not.
Updated vector3::reflection to now
actually work instead of returning the inverse of the reflection. Also reflection now doesn't return a unit vector but
instead a vector with the same length as the input vector.

Minor Changes

Renamed protected variable bmi (bitmap info) to bmi_, back_buffer to back_buffer_ and front_buffer to
front_buffer_
in window example.
Added material to sphere constructor
in sphere example.

Test Changes

Added tests for material and vector3::reflection to account for the new changes.
Renamed workflow template from Build Job to Build And Test CMake to better reflect what it does.

v0.2.3

Documentation hotfix, wrong formula in example.

Overview

Full Changelog: https://github.com/BardoBard/Bardrix/compare/v0.2.2...v0.2.3

Solved issue 32, where Mathematics didn't have a table of contents.
Updated incorrect formula in Raytracing example for calculating the light intensity at a certain point.
Updated incorrect formula in Raytracing example for calculating the intersection point of a sphere.

Documentation Changes

Solved issue 32, where Mathematics didn't have a table of contents.
Updated incorrect formula in Raytracing example for calculating the light intensity at a certain point.
Updated incorrect formula in Raytracing example for calculating the intersection point of a sphere.
Added next step to Introduction.

v0.2.2

Errors

In the sphere intersection it has an error which means this version (for raytracing example) is unstable.

Overview

Full Changelog: https://github.com/BardoBard/Bardrix/compare/v0.2.1...v0.2.2

Solved issue 30, where in the README it doesn't properly link to the
github.
Updated table of contents in Bardrix_Reference to include objects (material/shape).
Updated README in Examples/Raytracing, forgot to finish a sentence and updated table of
contents; which now also properly links.

Documentation Changes

Updated [Bardrix_Reference]Docs/(Bardrix_Reference.md) to include objects (material/shape).
Updated README in [Examples/Raytracing]Docs/(Examples/Raytracing/README.md), forgot to finish a sentence and updated table of
contents; which now also properly links.
Updated name from light_sphere_example.png to light_calculation_example.png
Updated 2.1 Light Sphere Intensity to Light Intensity.
Solved issue 30, where in the README it doesn't properly link to the
github.

v0.2.1

Errors

In the sphere intersection it has an error which means this version (for raytracing example) is unstable.

Overview

Full Changelog: https://github.com/BardoBard/Bardrix/compare/v0.2.0...v0.2.1

Added CONTRIBUTING.md to help contributors get started with the project.
Added more documentation to the codebase to help contributors understand the codebase.
Added a workflow to test the examples, this will help pushing correct code to the repository.

Documentation Changes

Added inverse square law example to Raytracing readme.
Added sphere light calculation example to Raytracing readme.
Added objects (shape, material) to Bardrix_Reference.
Added code and visual sphere intersection example to Raytracing readme.

Code Changes

Minor Changes

Updated raytracing example and window.cpp now doesn't
give a compiler error when running on an operating system other than Windows, instead it prints out a message that it is
not supported.
Added Examples/CMakeLists.txt to include all the examples in one build.
Renamed position to position_ and made it protected in sphere example.

Test Changes

Added a generic workflow for building and testing on multiple platforms.
Added a workflow for testing if the examples compile.

v0.2.0

Overview

Full Changelog: https://github.com/BardoBard/Bardrix/compare/v0.1.0...v0.2.0

The changes have backward compatibility issues (comared to v0.1.0), only if you were
using color::rgba(), color::rgba(unsigned) or color::color(unsigned).
Color now uses RRGGBBAA format instead of AABBGGRR format. This change was made to have a more consistent base color;
other colors will still be converted to this format and other formats.
window.h when compiling in clang works fine, yet when running on cl (microsft compiler) it does not work. This is due
the encoding, which has now been fixed and updated in window.h.

Documentation Changes

Updated Bardrix_Reference to include argb() and abgr() in color.
Added parameters to the math functions like degrees_to_radians Bardrix_Reference
Updated class diagrams to include argb() and abgr() in color.
Updated Raytracing cpp to include the new changes in color and center the screen.

Code Changes

Major Changes

Updated unsigned to uint32_t in color to always have a 32 bit integer representation.
Updated color to now represent the correct layout (RRGGBBAA instead of the previous AABBGGRR) for 32 bit integer
representation. This change means that previously used rgba() and rgba(rgba : unsigned) should be altered to
use abgr() instead.
Added argb() and abgr() to color (this will help with windows API which uses argb).

Minor Changes

Fixed small compiler compatibility issues fixed in Raytracer Example.
Added #include <cstdint> to bardrix.h to include uint32_t for color.

v0.1.0

Overview

This release changes to the API have been made, this is due to the fact that width and height in camera are
now int instead of unsigned. This is due to compatibility with other libraries that use int for width and height.
now call get_width(), get_height(), set_width(int), set_height(int).

shoot_ray(unsigned, unsigned, double) in camera now takes in int instead of unsigned for x and y. For the
same reason width and height are now int.

Added examples for simple raytracing.

Documentation Changes

Added examples to docs/ for a very simple demonstration of how to use Bardrix and raytracing.
Updated bardrix-math class diagram since in v0.0.5 it included reflect and refract instead of reflection
and refraction.
Updated bardrix-view class diagram to accommodate the new changes in camera.
Added release notes, this now gives more detail about the api changes happening in each release.
Added camera to the Bardrix_Reference.

Code Changes

Major Changes

Updated width and height to be int in camera. This is due to compatibility
with other libraries that use int for width and height. This changes does affect the api; due to the fact that now
you've got to call get_width(), get_height(), set_width(int), set_height(int).
Updated shoot_ray(unsigned, unsigned, double) in camera to take in int
instead of unsigned for x and y. This changes does affect the api; due to the fact that now you've got to
call shoot_ray(int, int, double).

Minor Changes

Added default constructor to camera with position (0, 0, 0), direction
(0, 0, 1), width 800, height 600 and fov 90.
Added << operator to camera to print out the camera's components.
Added bardrix:: prefix to all the functions and classes in objects.h and camera.h, sometimes there was an issue
with overriding; when using an external IDE like clion it would not copy with it the pre-fixes.

Test Changes

Added extra tests for camera to test the new changes.
Removed a print line in vector3_test.cpp that was not needed.
