Enumeration PositionModeConst

Position given in screen pixels ranging from [0, 0] in the lower left corner to [viewport.width, viewport.height] in the upper right corner.

Position given in normalized device coordinates, with [-1, -1] corresponding to the lower left of the screen, and [1, 1] to the upper right corner.

Position given in world space coordinates. Any positional offset is applied in world coordinates, meaning it is not transformed by the local to world transform.
