Abstract: The present disclosure relates to a rendering method for generating an image of an assembling toy formed by coupling a plurality of assembling elements arranged in a virtual space. The rendering method includes placing a virtual camera, which is an origin of a ray of light traveling in the virtual space, in the virtual space; emitting a virtual ray from the virtual camera; and determining a pixel value of a pixel corresponding to the virtual ray among pixels of the image in consideration of characteristic information of a transparent assembling element when the virtual ray hits the transparent assembling element among the plurality of assembling element wherein the characteristic information includes at least a transmittance albedo and a reflection albedo.
