Embodiment Construction

[0079] The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that the described embodiments are only intended to facilitate the understanding of the present invention, rather than limiting it in any way.

[0080] The ink painting simulation method of the three-dimensional tree model of the present invention first divides the tree model reasonably into three parts: trunk, branches and leaves, and then renders and draws respectively according to the different characteristics of each part. Simulation method flow process of the present invention can be found in figure 1 . For the trunk part, the improved two-dimensional texture mapping rendering method is used to directly map the defined texture image to the three-dimensional trunk model to generate the trunk with ink effect; for the branch part, the average value of the trunk texture color is used to directly fill the branches with color; ...

Abstract

The ink painting simulation method of the three-dimensional tree model first divides the tree model into three parts: trunk, branches and leaves, and then renders and draws them respectively. For the trunk part, use the rendering method of two-dimensional texture mapping to directly map the defined texture image to the three-dimensional trunk model to generate ink effect; for the branch part, use the mean value of the trunk texture color to directly fill the branch with color; for the leaf part , including model simplification, pen picture construction, drawing direction determination, ink color determination, brush model construction and drawing shading. Through these steps, the artistic style simulation of ink painting of leaves is completed. The method for simulating Chinese ink painting on three-dimensional trees provided by the present invention can not only realize the simulation effect of ink painting on three-dimensional trees, but also can be made into a plug-in for 3D model processing software such as 3DMax and Maya, and can be applied to art education and digital entertainment , 3D animation and games and other fields.

Description

technical field [0001] The invention belongs to the related research field of non-realistic rendering of computer graphics, and relates to an ink painting simulation method of a three-dimensional tree model. Background technique [0002] With the development of computer graphics, the realistic drawing in traditional graphics reflects the reality too accurately, and feels relatively blunt, which makes some important details not properly emphasized, and lacks the artistic style that paintings should have. It is difficult to express the artistic conception that the artist wants to express. In order to solve this problem, non-photorealistic rendering technology emerged as the times require, and has become a research hotspot in computer graphics. [0003] Through the evolution and development of Chinese ink painting for thousands of years, it has not only formed many styles and techniques, but also due to the unique artistic effect and painting mechanism of ink painting, it is d...
