Detailed Description

Input handling adapter for the Camera system.

This module bridges raw input events (keys, mouse, scroll) to the Camera's internal state and logic. It decouples the input source (e.g., GLFW) from the Camera implementation.

Function Documentation

camera_input_handle_key()

void camera_input_handle_key	(	Camera *	cam,
		int	key,
		int	action
	)

Processes a keyboard event to update camera movement flags.

Maps specific keys (W, A, S, D, Q, E) to camera movement directions.

Parameters

cam	Pointer to the Camera instance.
key	The key code (e.g., GLFW_KEY_W).
action	The key action (e.g., GLFW_PRESS, GLFW_RELEASE).

camera_input_handle_mouse()

void camera_input_handle_mouse	(	Camera *	cam,
		double	xpos,
		double	ypos
	)

Processes a mouse movement event to update camera orientation.

Calculates the delta from the last known position stored in the Camera struct and applies rotation (yaw/pitch).

Parameters

cam	Pointer to the Camera instance.
xpos	The current absolute X coordinate of the mouse.
ypos	The current absolute Y coordinate of the mouse.

camera_input_handle_scroll()

void camera_input_handle_scroll	(	Camera *	cam,
		double	yoffset
	)

Processes a scroll event to adjust camera speed or zoom.

Parameters

cam	Pointer to the Camera instance.
yoffset	The vertical scroll amount.
