Embodiment Construction

[0022] The present invention will be further described below in conjunction with the accompanying drawings.

[0023] refer to figure 1 , an interactive virtual plant dynamic visualization method, comprising the following steps:

[0024] (1) The experiment records the topology and geometry of plants. Recording the topological structure and geometric shape of plants in different environments is the basis for modeling virtual plant models. The geometric form records the outline, color, size, angle, etc. of the organ. The recording cycle of plant topology is once every 7 days.

[0025] (2) Extraction of topological structure and establishment of organ shape library. Parametric L system is a commonly used morphogenetic model in virtual plant modeling. The recorded plant topology is described by a parameterized L system and stored in computer memory. The organ shape library uses computer graphics technology to save the recorded plant organ geometry in the form of three-dimensi...

Abstract

The invention discloses a method for dynamically visualizing interactive virtual plants. The method comprises the following steps of: (1) recording a plant topological structure and a geometric shape by an experiment; (2) extracting the topological structure, establishing an organ shape library, and describing a parameterized L system of the plant topological structure; (3) improving the parameterized L system, wherein the improved parameterized L system is formed by adding age parameters into characters which are representative of plant organs such as branches, stems, leaves, fruits and flowers, adding deflection angle parameters representing an external force action into parameters of the organs such as the branches, the stems and the leaves, and showing the shape change of the plants under the external action by using angular change; (4) computing shape parameters of a plant model by static environment factors which are input by a user according to a predetermined condition determination function; and (5) dynamically visualizing a virtual plant model. By the method, dynamic interaction can be effectively improved, and good practicability is provided.

Description

technical field [0001] The invention relates to computer graphics technology, in particular to a method for realistically simulating plants in natural scenes by applying computer graphics technology. Background technique [0002] The growth of plants is inseparable from the external environment. Temperature, light, water, nutrition, etc. not only affect the yield and quality of plants, but also affect the shape of plants. Plants in different growth environments have different structural characteristics. The water orientation of roots, the effect of day length on the flowering period of photosensitive plants, etc., indicate that the external environment is oriented to plants. In recent years, the physiological and ecological model based on the mechanism process has been combined with the visual plant model. The former is used to simulate the impact of ecological environment and cultivation measures on plant biomass, organ formation and development; the visual model is used...
