1. A method for generating procedural textures for a computer having a unified CPU/GPU memory architecture in which data exchanges between a CPU and a GPU consist in memory address exchanges in a unified CPU-GPU memory, the method allowing textures for contents that are managed by the 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 data of a graph consisting of a plurality of filters and sequentially traversing said graph using a sequencer and the unified CPU-GPU memory whereby data exchanges between the CPU and the GPU consist in memory address exchanges in the unified CPU-GPU memory, the unified CPU-GPU memory being provided with a memory area M 1 that contains target data containing a best suited processing target among CPU processing only or GPU processing only, of each filter, such as to allow, for each filter traversed: identifying, based on the target data containing the best suited processing target among CPU processing only or GPU processing only, one of a CPU only processor or a GPU only processor that has been preselected for executing each filter; receiving, from at least one instruction module corresponding to the preselected CPU only or GPU only processor, CPU instructions when the preselected processor is the CPU, provided in a memory area M 3 of the unified CPU-GPU memory which contain the CPU instructions associated with each filter, in their CPU versions, or GPU instructions when the preselected processor is the GPU, provided in a memory area M 4 of the unified CPU-GPU memory which contains the GPU instructions associated with each filter, in their GPU versions; receiving, from at least one filter storage module, parameters of a current filter provided in a memory area M 0 of the unified CPU-GPU memory, initialized during graph generation, containing a list of filters to be activated, parameter values for each filter, and dependencies between various filtering steps; receiving, from at least one buffer storage module, buffer addresses of the current filter provided in an area M 2 of the unified CPU-GPU memory which contains working buffers data of a rendering engine for temporary image data obtained during processing by the CPU or GPU; applying the parameter values provided for digital valued filter inputs; executing the filter instructions with the parameter values such as to execute the filter on the best suited processing target providing a minimal global calculation time; storing intermediate results obtained by executing the filter instructions; and when all of the filters of the graph have been executed by the CPU and the GPU, generating, using a rendering engine, at least one display texture.
