Embodiment Construction

[0044] The specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0045] refer to figure 1 As shown, taking powdery mildew as an example, the lesion rendering method in the embodiment of the present invention is introduced.

[0046] S1. Simulation of dynamic spatial information of lesion based on cell texture

[0047] The present invention divides the dynamic spatial information of the disease spot of powdery mildew into three aspects: the distribution of the disease spot, the movement mode of the disease spot, and the final form of the disease spot. Some simple assumptions are made for the above three aspects of lesion space information:

[0048] Distribution of lesions:

[0049] A, powdery mildew bacteria, there is competition for ...

Abstract

The invention relates to the field of combination of computer graphics, real-time realistic rendering and plant behavior simulation, and discloses a plant leaf scab rendering method. The plant leaf scab rendering method comprises the following steps of: S1, generating cell texture, and simulating scab dynamic spatial information of the plant leaf surface according to the generated cell texture, and the scab dynamic spatial information comprises the information on three aspects: the distribution of scabs, the movement mode of the scabs and the final form formed by the scabs; and S2, simulating leaf appearance variation in a germ diffusion process by utilizing a shell model, so that the rendering of the scabs is realized. By the plant leaf scab rendering method, the plant leaf scab rendering can be realized; and the leaf appearance variation in the germ diffusion process is truly simulated.

Description

technical field [0001] The invention relates to the field of combining computer graphics, real-time realistic rendering and plant behavior simulation, in particular to a method for rendering diseased spots on plant leaves. Background technique [0002] In recent years, with the continuous development of agricultural information technology, 3D animation has gradually become an important means of agricultural knowledge popularization and technical training. 3D animation for agriculture not only needs to have realistic visual effects, but also needs to display agricultural knowledge correctly. Therefore, how to carefully combine 3D visual effects with agricultural knowledge has become an urgent problem to be solved. Popular science training animations mainly show farmers the basic knowledge, common problems and professional technical methods in agricultural production. Among them, pests and diseases are very common physiological phenomena in agricultural production. However, t...
