The embodiment of the invention discloses a method for a UE to select a resource, a UE and a computer program. The roof rack assembly includes a support member adapted to be fixedly secured to the roof. The earth removal member further includes a blade. A micro-lens array with a micro-lens positioned above each pixel directs light illuminating the pixel toward the central portion of the pixel and away from its edges. The color value for the pixel being rendered will be based on the perturbed normal vector instead of the normal vector.
