A method for texturing a mesh associated with a surface representative of a scene captured in a plurality of images, wherein at least a mesh element of the mesh is at least partially visible from at least two first images of the plurality of images. The composite band forms a loop having two or more rigid segments and a flexible segment coupled between the rigid segments. The third lens unit includes, in order from the object side to the image side, two lenses having concave surfaces that face each other with a largest air gap in the third lens unit provided therebetween, and a positive lens. The light polarized by the polarization conversion unit may maintain its polarization state when it is subsequently emitted from the light guide plate. Damage or rupture of the sealed housing due to an increase or decrease in pressure within the housing may be avoided while reducing introduction of moisture into the housing by venting the housing through a tube to a location having a relatively lower humidity.
