1. A method for generating procedural textures for a computer having a unified CPU/GPU memory architecture in which data exchanges between the CPU and the GPU consist in memory address exchanges in the unified CPU and GPU memory, said method allowing textures for contents that are managed by a graphics processor (GPU) to be generated from digital data and operators of a plurality of procedural filters interpreted by means of a rendering engine, and including the steps of: receiving the data of a graph consisting of a plurality of filters and sequentially traversing said graph such as to allow, for each filter traversed, the steps of: identifying, based on identification data of filter execution targets, the CPU or GPU processor that has been preselected for executing this filter; receiving, from at least one instruction module corresponding to the type of preselected CPU or GPU processor, the instructions for the preselected CPU or GPU version of the filter; receiving, from at least one filter storage module, parameters of the current filter; receiving, from at least one buffer storage module, the buffer addresses of the current filter; applying the values provided for the digital valued filter inputs; executing the filter instructions with the set parameters; storing the intermediate results obtained; and when all of the filters of the graph have been executed, generating at least one display texture.
