Detailed Description

cpp

class InputManager;

class InputManager;

Class handling all GLUT interaction events (mouse and keyboard) and starting the label editor.

This class stores state of all keys and mouse buttons in a map keyMap - used for controlling all interaction. It also updates the stored statuses of the keys from JUST pressed/released to pressed/release. The update() is called regularly from the end of main.cpp: logicUpdate()
