Simple program for testing your math library.

Matrices should be stored in row major order.

Add your class files (vec3.h, vec4.h, mat4.h) to the root directory and add them to the list of files located in CMakeLists.txt

Build and run test by executing the run_test.bat file, or by using CMake GUI.

Make sure to implement according to the following class descriptions, or modify the test so that it uses your own naming convention and coding style.

Syntax

• name: type = variable or parameter/argument
• f32 = 32 bit floating point number
• const& = const reference
• + = public variable or method
• - = private variable or method
• name(args) [const]:return_type = function or method, const denotes the method should not modify the object.

Optional functions

Add #define TEST_VIEW_PERSPECTIVE to top of main.cc to test perspective and view matrix functions.

Add #define USE_LH to configure perspective and view to be left-handed instead of right-handed
