Detailed Description

Processes input and calculates the View Matrix for OpenGL rendering.

• Implements a standard Euler Angle (Yaw/Pitch) FPS camera.

Constructor & Destructor Documentation

Camera()

Core::Camera::Camera ( Vec3  startPos = Vec3(0.0f, 0.0f, 0.0f), Vec3  startUP = Vec3(0.0f, 1.0f, 0.0f)  )

inline

Constructs the camera at a specific position.

Parameters

startPos	Initial world space position.
startUP	World's "Up" direction (usually 0,1,0).
