A system for generating procedural textures on an object using physical ink data and physical applicator data, comprising: - access to physical ink data comprising a plurality of parameters among the following: color, viscosity, temperature, drying rate, chemical composition, transparency level; - access to physical applicator data comprising a plurality of parameters among the following: width, depth, thickness, profile, roughness, porosity, flexibility of the applicator; - access to target object data comprising target object data which may be modified by the applied physical parameters; - access to mixing rule and function data; - access to original physical procedural texture T data; - a microprocessor and control instructions; - a before-projection on the target object off-object virtual rendition generator module which is provided to combine the physical ink data with the physical applicator data; - off-object virtual rendition data (8, 9) comprising the rendition data obtained after combining the ink data and the physical applicator data before projection on the target object; - a before-projection on the target object off-object virtual rendition transformation module which is provided to adapt the data of said off-object rendition to a given rendition projection mode on the target object; - a physical parameter integrator module which is provided to generate a new set of procedural textures T + 1 for said target objects(s), taking into account the object data, the procedural texture set T data, the before-projection virtual rendition data which are transformed as a function of the type of projection to be effected; and - further including a temporal storage module which is provided to keep the data required to generate, again, a set of procedural textures of an object for which one or more parameters are modified, or to return to an earlier step of a process, in the condition in which the parametric architecture was in said earlier step. - access to physical ink data comprising a plurality of parameters among the following: color, viscosity, temperature, drying rate, chemical composition, transparency level; - access to physical applicator data comprising a plurality of parameters among the following: width, depth, thickness, profile, roughness, porosity, flexibility of the applicator; - access to target object data comprising target object data which may be modified by the applied physical parameters; - access to mixing rule and function data; - access to original physical procedural texture T data; - a microprocessor and control instructions; - a before-projection on the target object off-object virtual rendition generator module which is provided to combine the physical ink data with the physical applicator data; - off-object virtual rendition data (8, 9) comprising the rendition data obtained after combining the ink data and the physical applicator data before projection on the target object; - a before-projection on the target object off-object virtual rendition transformation module which is provided to adapt the data of said off-object rendition to a given rendition projection mode on the target object; - a physical parameter integrator module which is provided to generate a new set of procedural textures T + 1 for said target objects(s), taking into account the object data, the procedural texture set T data, the before-projection virtual rendition data which are transformed as a function of the type of projection to be effected; and - further including a temporal storage module which is provided to keep the data required to generate, again, a set of procedural textures of an object for which one or more parameters are modified, or to return to an earlier step of a process, in the condition in which the parametric architecture was in said earlier step.
