Emotional Design of Fabric Sofa CMF Based on Interactive Genetic Algorithm

Interactive Genetic Algorithm (IGA) is a common algorithm for design solution optimization, which needs to be evaluated based on visual population solutions. The technology for automatic batch generation of visual populations for material design is currently imperfect.The work aims to address this bottleneck and provide a technical basis for intelligent optimization techniques to serve CMF design. The texture organization of woven fabric sofas was coded to drive the automatic generation of bump maps, develop a batch construction technique for 3D product CMF design solutions. Two emotional evaluation indicators, aesthetics and visual body feeling were introduced to identify the implicit designer''s imagery information through the evaluation data and promote the optimization and iteration of solutions. A series of genetic operations such as batch generation of CMF visualization solutions for fabric sofas and their emotive evaluation, cross recombination, variation, etc. were achievedto promote the optimization of CMF design solutions. The case application shows that the proposed texture coding-driven bump mapping automatic generation method is technically feasible for the batch generation of 3D product CMF design solutions, and the automatically rendered CMF solutions can meet the interactive evaluation needs of emotional metrics in terms of efficiency and realism.
