apply_orbit_rotate()

MAYAFLUX_API void MayaFlux::Kinesis::apply_orbit_rotate	(	OrbitState &	state,
		float	dx,
		float	dy
	)

Apply a mouse delta to azimuth and elevation.

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

Parameters

state	Orbit state (azimuth, elevation mutated).
dx	Horizontal pixel delta (positive = right).
dy	Vertical pixel delta (positive = down).

{
    st.azimuth += dx * st.rotate_sensitivity;
    st.elevation += dy * st.rotate_sensitivity;
 
    static constexpr float k_limit = glm::radians(89.0F);
    st.elevation = glm::clamp(st.elevation, -k_limit, k_limit);
}
