Abstract:

Plant 3D shape design based on computer aided design (CAD) is an important technology for plant visualization. Evaluation factors of 3D geometric digital design for plant are presented in order to standardize plant digital modeling. However, it is limited by some problems with ambiguous aim, non-uniform flow, non-standardized technology, and hard evaluation. In this paper, main functional and technical factors were discussed based on the analysis of computer aided design technology and evaluation system. Aims and requirements of 3D geometric digital design for plant were summed up, and several functional evaluation reasons and technical evaluation reasons were discussed, respectively. Finally, a synthetic evaluation model was presented in order to provide an example of the evaluation system. The proposed evaluation system provides a basis and reference for standardization quantification of digital plant design, as well as the development in plant modeling.

Key words: plant, 3D shape, digital design, evaluation factors, synthetic evaluation model
