Coordinated organization of groups of cells in the plane of an epithelium, such that they all orient to similar coordinates. The process whereby the developmental fate of a cell becomes restricted such that it will develop into a compound eye photoreceptor cell. A photoreceptor cell is a cell that responds to incident electromagnetic radiation. Different classes of photoreceptor have different spectral sensitivities and express different photosensitive pigments. Any cellular process that results in the specification, formation or maintenance of anisotropic intracellular organization or cell growth patterns. The process whereby a relatively unspecialized cell acquires the specialized features of an eye photoreceptor cell. The process by which the anatomical structures of the compound eye are generated and organized. Morphogenesis pertains to the creation of form. The adult compound eye is a precise assembly of 700-800 ommatidia. Each ommatidium is composed of 20 cells, identified by cell type and position. An example of compound eye morphogenesis is found in Drosophila melanogaster. The process whereby relatively unspecialized cells acquire the specialized features of R3 and R4 photoreceptors. An example of this process is found in Drosophila melanogaster. The process whereby the R3/R4 photoreceptors commit to their cell fate. R3 and R4 are paired photoreceptors which contribute the outer rhabdomeres. The process whereby the developmental fate of a cell becomes restricted such that it will develop into an eye photoreceptor cell. A photoreceptor cell is a cell that responds to incident electromagnetic radiation. Different classes of photoreceptor have different spectral sensitivities and express different photosensitive pigments. The specification of polarized ommatidia. Ommatidia occur in two chiral forms. The trapezoidal arrangement of photoreceptors in the dorsal part of the eye is the mirror image of that in the ventral part.
