apply_mouse_delta()

void MayaFlux::Kinesis::apply_mouse_delta	(	NavigationState &	state,
		float	dx,
		float	dy
	)

Apply a mouse delta to yaw and pitch.

Pitch is clamped to [-89, +89] degrees to avoid gimbal lock at the poles.

Parameters

state	Navigation state (yaw, pitch mutated)
dx	Horizontal pixel delta (positive = right)
dy	Vertical pixel delta (positive = down)

    st.yaw += dx * st.mouse_sensitivity;
    st.pitch += dy * st.mouse_sensitivity;
 
    static constexpr float k_limit = glm::radians(89.0F);
    st.pitch = glm::clamp(st.pitch, -k_limit, k_limit);
