:A method of displaying a visual representation of a luminaire comprises obtaining a three-dimensional model of the luminaire and one or more texture maps associated with the three-dimensional model, determining a camera location and orientation based on user input, and determining observation angles on each of a plurality of surface positions of the three-dimensional model based on the camera location and orientation. The visual representation includes a representation of a light effect generated by one or more activated light sources in or on the luminaire, the one or more light sources and the luminaire are rotatably symmetric with respect to a central axis of the luminaire, and the surface of the luminaire comprises a plurality of repeating sections. The method further comprises determining, for each of the plurality of surface positions, an applicable light value for a respective surface position based on the observation angle determined for the surface position and a light value predetermined either for the surface position or for a corresponding surface position of a different section of the luminaire, and rendering the visual representation of the luminaire based on the three-dimensional model, the one or more texture maps, the applicable light values, and the camera location and orientation. At least some of the applicable light values are determined based on light values predetermined for corresponding surface positions of a different section of the luminaire.
