Abstract

The invention relates to a full-color layered slicing algorithm based on a three-dimensional model of texture mapping. The full-color layered slicing algorithm based on the three-dimensional model oftexture mapping includes the steps that a three-dimensional model file of texture mapping is analyzed, a triangular mesh adjacent topological relation based on color information is established, and fast query of triangular mesh adjacent information of the color information is realized; the fast intersection operation of color information triangular meshes and a tangent plane is realized, positioncoordinates and texture coordinates of all vertexes in each layer are obtained, the vertexes are connected in sequence to form a full-color two-dimensional contour, and the full-color two-dimensionalcontour is filled; and a full-color bitmap is generated, the position of the full-color contour in the bitmap is precisely located according to the position of a colourless model in a printing platform, the thickness of the contour is increased appropriately, and the function of layer-upon-layer printing and layer-upon-layer coloring is achieved. The full-color layered slicing algorithm based on the three-dimensional model of texture mapping has high slicing efficiency, the surface colors of the model are realistic, the reduction degree is high, the aftertreatment process of coloring the modelis omitted, the requirement for proficiency of operators is greatly reduced, the forming quality of parts is improved, and a real sense of color three-dimensional printing is realized.

Description

technical field [0001] The invention relates to a slicing method of a three-dimensional model, in particular to a method based on texture stickers Figure three A full-color hierarchical slicing algorithm for dimensional models. Background technique [0002] With the rapid development of 3D printing technology in recent years, 3D printing no longer only exists in laboratories, but is more and more used in industries, medical care, education, design and other fields, just like other technologies, such as Movies, television, cameras, etc., have gradually developed from "colorless" to color. Color itself carries a lot of information that people can rely on to distinguish different components of things. In the field of design, the surface of the sample can be colored to enhance the performance; in the field of education, the surface of the model can also be colored to distinguish different components and enhance the teaching function. [0003] At present, in order to obtain co...

Problems solved by technology

[0005] The purpose of the present invention is to solve the above technical defects: artificial coloring in the later stage is time-consuming and laborious, and the coloring effect is also heavily dependent on the proficiency of the operator; the current layered slice algorithm cannot handle the texture map of the 3D model, and cannot perform color 3D printing , providing texture based stickers Figure three Full-color hierarchical slice algorithm for dimensional models
