- Updated renderer.h to replace Vec3 and Vec2 structs with Math namespace equivalents. - Introduced Texture struct to manage texture properties. - Modified Triangle struct to use Texture instead of GLuint for texture handling. - Removed deprecated matrix functions and replaced them with Math namespace methods. - Implemented InputManager class for better input handling, including key and mouse state tracking. - Added ObjLoader class to load OBJ files and associated textures, with MTL file parsing. - Created math utilities for fixed-point arithmetic and vector/matrix operations. - Added time management class for frame timing and delta time calculations.
