Abstract: A real-time rendering method of a three-dimensional object comprising the following phases: performing the rendering of the substantially opaque elements by realizing at least one first image, performing a plurality of sequential steps, wherein the transmissive elements are rendered from the furthest to the closest to the virtual video/photo-camera according to a predetermined ordered list by realizing a respective plurality of second images, where in the first step transmissive elements furthest away from the virtual video/photo-camera are rendered using the at least one first image to determine the spectrum of the light directed towards the virtual video/photo-camera coming from the transmissive elements to be rendered, and where in each step i one or more transmissive elements are rendered using the second image obtained in the immediately preceding step to determine the spectrum of the light directed towards the virtual video/photo-camera coming from the transmissive elements to be rendered.

Abstract: A computer-implemented method is provided for measuring optometric values and for manipulating a glasses frame remotely in order to manufacture lenses and provide customized glasses for a person. The method includes providing aesthetic indications on the correct position of the glasses in relation to the person's head, and assessing a degree of comfort in relation to the possibility of deformation of the arms and frame.
