Optimization of the Virtual Scene Layout Based on the Optimal 3D Viewpoint

At present, visual and parametric designs have been widely used in architectural design, urban planning and landscape design for design inspiration. Highly integrated auxiliary design software has become more prevalent and greatly changed the traditional way of working with architectural design and urban planning with parameterised operations, convenient editing methods and efficient workflows. However, these methods for layout optimisation have more or fewer problems, such as humdrum forms, lack of aesthetic principles, and difficulty adapting to the layout optimisation of complex architectural environments, and usually presented obstacles to the users’ understanding of hierarchical relationships in complex environments. This paper presents a novel 3D scene layout optimisation method that combines scene view information with an interactive genetic algorithm to optimise the virtual environment’s layout. We apply the visual perception information of 3D building models to improve the scene’s layout and integrate the evaluation of visual salient features with other factors to realise the intelligent scene’s layout based on optimal 3D viewpoints and a genetic algorithm. The experimental results show that our method can efficiently optimise the layout of the 3D building environment, and it has innovation and practical application value in the fields of architectural visualisation, 3D animation, landscape planning and game design.
