Reference: setCameraPos
setCameraPos(v) sets the camera position to v ∈ R^3 in the current 3D visualization window. setCameraPos(v, d) sets the camera position to v ∈ R^3 in the current 3D visualization window. The camera is looking in the d ∈ R^3 direction. setCameraPos(v, d, u) sets the camera position to v ∈ R^3 in the current 3D visualization window. The camera is looking in the d ∈ R^3 direction, and u ∈ R^3 is the vertical (up) direction.
