Abstract

The invention relates to a method and device for drawing a three-dimensional model on a two-dimensional plane, and the method comprises the steps: obtaining the three-dimensional model, and generating a corresponding top view through a UV decomposition method; performing parameter conversion on the three-dimensional parameters of the top view, and determining two-dimensional parameters corresponding to the top view; performing parameter conversion on the two-dimensional parameters corresponding to the top view, updating the three-dimensional parameters of the three-dimensional model, and determining the updated three-dimensional model; judging whether the updated three-dimensional model meets a model precision condition or not, and outputting the updated three-dimensional model if the updated three-dimensional model meets the model precision condition; and if the model precision condition is not met, taking the updated three-dimensional model as a re-acquired three-dimensional model, and returning to the step of generating the corresponding top view through the UV decomposition method. The updated three-dimensional model is generated through UV decomposition and coordinate conversion, and UV decomposition is performed on the updated three-dimensional model again until the precision requirement is met, so that the 3D modeling efficiency and convenience are improved.

Description

technical field [0001] The invention relates to the technical field of three-dimensional modeling, in particular to a method and device for drawing a three-dimensional model on a two-dimensional plane. Background technique [0002] In the process of developing 3D model software products, it is usually necessary to combine and package the already produced models to form a 3D model product with a certain scale. In this process, coordinate transformation technologies such as model movement and rotation are often used. At present, most of the 3D software products on the market implement designers that operate in 3D space, and this modeling method has some disadvantages. On the one hand, the existing modeling methods perform multiple transformation operations in 3D space. Due to the complexity of 3D space, the accuracy of the operation is not high. It is difficult to accurately draw the model; on the other hand, the existing modeling method is complex and cumbersome in the thre...
