Detailed Description

Minimal FPS-style camera with yaw/pitch look and WASD-style motion.

Maintains position and an orthonormal basis (direction/right/up) derived from Euler yaw/pitch angles. The camera supports continuous motion toggled via boolean flags (front/back/left/right) and optional mouse-look. The view matrix is produced with a standard look-at helper.

Usage:

Camera cam({0,0,3});
cam.enableMouse();
// Per-event:
cam.mouseMove(x, y);     // when mouse moves
cam.moveFront(true);     // on key press; set to false on release
cam.updatePosition();    // once per frame
Mat4 V = cam.viewMatrix();
