Abstract

The invention discloses a display method of growth of a virtual plant, which is implemented in the following steps: establishing a static three-dimensional model of a virtual plant organ based on pictures in the plant growth process; judging whether the display resolution is a low resolution, an intermediate resolution or a high resolution based on the observation distance; and when the display resolution is respectively the low resolution, the intermediate resolution or the high resolution, adopting the static three-dimensional model of the virtual plant organ to correspondingly draw out a dynamic three-dimensional model in the virtual plant growth process, a dynamic three-dimensional model in the virtual plant organ growth process or textures of the static three-dimensional model of thevirtual plant organ respectively, and displaying. The invention can display the growth change process of the virtual plant in a multi-resolution and dynamic manner, can satisfy the requirements of macroscopic and microcosmic display and has more authentic and accurate display effect.

Description

technical field [0001] The invention relates to the field of computer three-dimensional image processing, in particular to a display method for virtual plant growth. Background technique [0002] Computer 3D image processing technology can be used in the field of plant growth control, such as using dynamic 3D models to display the growth process of virtual plants. The visual display of virtual plant growth refers to visually reproducing the growth process of plants on the computer, which can be applied to agricultural and forestry production guidance, yield prediction, crop breeding, seedling monitoring, water and soil conservation, environmental greening, auxiliary landscape design, teaching and training etc. The study of virtual plants originated in 1968 by American biologist Lindenmayer (LINDENMAYER A. Mathematical models for cellular interactions in development I. Filaments with one-sided inputs [J]. Journal of Theoretical Biology, 1968, 18(3): 280-99 .And LINDENMAYER ...
