Three-dimensional texture mapping method and device and computer readable storage medium

Abstract

The invention discloses a three-dimensional texture mapping method and device and a computer readable storage medium, and the method comprises: obtaining a to-be-mapped region of a to-be-printed three-dimensional model; unfolding a three-dimensional grid corresponding to the to-be-mapped area, and establishing a two-dimensional grid corresponding to the three-dimensional grid; adding a preset texture picture to the two-dimensional grid to obtain a corresponding two-dimensional texture grid, and obtaining a three-dimensional texture grid corresponding to the two-dimensional texture grid according to the two-dimensional texture grid; and slicing the three-dimensional texture grids to obtain sliced three-dimensional texture grids, wherein the step of obtaining the slice data comprises the sub-steps of calculating the slice layer number of the to-be-mapped area, calculating the contour line of each layer of slice layer by layer to obtain the slice data, wherein when the contour line of thecurrent layer of slice is calculated, the grid data related to the current layer of slice topology is reserved, and the grid data unrelated to the current layer of slice topology is cleared. By adopting the scheme, the storage space occupied in the three-dimensional texture mapping process can be reduced.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of 3D printing, and in particular to a method and device for three-dimensional texture mapping, and a computer-readable storage medium. Background technique [0002] Before 3D printing a model, it is usually necessary to process the image of the model to be printed. In the process of processing the image of the model to be printed, there are a large number of three-dimensional texture maps that need to be generated, such as reliefs, shoe bites, etc. [0003] At present, when performing image processing on 3D texture maps, the generated 3D mesh data volume is large, resulting in large memory consumption and affecting the stability of image processing software. Contents of the invention [0004] The technical problem solved by the invention is how to reduce the storage space occupied in the process of three-dimensional texture mapping. [0005] In order to solve the above-mentioned te...
