Abstract: A method for 3D rendering, including receiving a group of 3D triangles defining a mesh of a surface, each 3D triangle in the group having 3D vertices with respective 3D coordinates, and transforming each 3D triangle into a 2D triangle having 2D vertices corresponding respectively to the 3D vertices, each 2D vertex having respective 2D pixel coordinates and a triplet of pixel attributes corresponding to the 3D coordinates of a corresponding 3D vertex. Each 2D triangle is passed to a graphics processor, which treats the triplet of pixel attributes of each 2D vertex as interpolatable values. The graphics processor computes respective triplets of interpolated pixel attributes for pixels within each 2D triangle by interpolation between the pixel attributes of the 2D vertices, and a 3D image of the surface is rendered by converting the interpolated pixel attributes computed by the graphics processor into voxel coordinates in the 3D image.

Abstract: A technique for controlling order of selecting elements from an ordered set of N elements, the technique provides applying to the ordered set a mathematical function P converting the order, in which the elements are preliminarily ordered in the set, into a desired order defined by the function P. The elements may further be selected from the set according to the new order defined by the function P. The elements in the set comprise at least one of the following: devices, items, parameters, values.

Abstract: A method and a system for lighting control, which utilize assigning to a specific fixture (lighting instrument) at least one virtual parameter convertible into one or more physical parameters of the fixture, for further controlling the fixture by controlling the mentioned at least one virtual parameter.
