Embodiment Construction

[0078] 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, but do not have any limiting effect.

[0079] The ink painting simulation method of the three-dimensional tree model of the present invention first reasonably divides the tree model into three parts: trunk, branches and leaves, and then renders and draws respectively according to the different characteristics of each part. For the flow of the simulation method of the present invention, see figure 1 . For the trunk part, an 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 tree 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 invention discloses an ink painting simulation method of a three-dimensional tree model. The ink painting simulation method of the three-dimensional tree model includes the following steps: dividing the tree model into a trunk portion, a branch portion and a leaf portion, and conducting rendering and drawing on the three portions respectively; for the trunk portion, directly mapping defined texture images to the three-dimensional tree model to generate ink painting effects by adopting a render method of two-dimensional texture mapping; for the branch portion, directly conducting color filling on branches by using average values of branch texture colors; and for the leaf portion, conducting model simplification, stroke surface construction, drawing direction confirmation, ink color confirmation, brush pen construction and drawing render to complete ink painting artistic style simulation of leaves. According to the ink painting simulation method of the three-dimensional tree model, ink painting simulation effects of the three-dimensional tree model are achieved, and the method can be made into plugins which can be used in three-dimensional processing software of 3D Max, Maya and the like, and the ink painting simulation method of the three-dimensional tree model can be further applied in fields of art education, digital entertainment, 3D animations, games and the like.

Description

technical field [0001] The invention belongs to the related research field of computer graphics non-realistic rendering, and relates to an ink painting simulation method of a three-dimensional tree model. Background technique [0002] With the development of computer graphics, photorealistic rendering in traditional graphics is too accurate to reflect reality, and feels relatively rigid, 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 emerges as the times require, which has become a research hotspot in current computer graphics. [0003] Through the evolution and development of thousands of years, Chinese ink painting has not only formed many styles and styles, but also has many techniques. Due to the unique artistic effect and painting mechanism of in...
