Lightweight 3D tree model construction method supporting personalized skeleton editing

Abstract

Disclosed is a light-weight three-dimensional tree model building method supporting skeleton personalization edition. According to the light-weight three-dimensional tree model building method supporting skeleton personalization edition, on the basis that an original tree model skeleton structure is extracted, the tree model skeleton details are edited in a personalization mode through man-machine interaction, and a three-dimensional tree model with the brand new skeleton structure is formed. On this basis, a limb reconstruction method based on a circular truncated cone and a crown reconstruction method based on convex hull texture template mapping are adopted, light-weight reconstruction is conducted on the limbs portions and the crown portion of the three-dimensional tree model which is edited in a personalization mode, and therefore the three-dimensional tree model for a mobile terminal is built rapidly in a diversified mode.

Description

technical field [0001] The invention relates to a lightweight three-dimensional tree model construction method of computer graphics. Background technique [0002] The construction and fast rendering of 3D scenes has become an important research field in computer graphics research. Trees are not only seen everywhere in the real life environment, but also an indispensable plant type in nature. They also play an important role in virtual 3D scenes, such as: 3D animation, 3D online games, movie special effects, garden design, urban Planning and military simulation and other fields. The 3D tree model is an important factor affecting the immersion and realism of the virtual environment. A 3D scene lacking trees will become eclipsed. Similarly, using realistic 3D tree models of various shapes in the scene can greatly improve the fidelity and realism of the scene, enhance the user's visual perception, and give people a sense of The feeling of being there. [0003] Due to the var...

AI Technical Summary

Problems solved by technology

At the same time, the 3D tree model constructed by the existing modeling method contains a huge amount of information and data, which not only increases the storage space of the application system, but also increases the rendering time of the 3D scene and the network application. Model transfer time

In addition, due to the limitations of current network factors such as network bandwidth, delay and congestion, and mobile terminal hardware conditions, the real-time performance of the 3D plant model's synchronous operation in mobile terminal applications is seriously affected.
