virtual EMMA_EXPORT Fusion::Vec3f project (  const Fusion::Vec2f &  point  )  [pure virtual]

Apply the projector using the given point, returning the point in three dimensions that it projects to. The point should be normalized from 0-1, with (0,0) at the lower-left. Implemented in SpherePlaneProjector, SphereSectionProjector, and SphereSheetProjector.
