Abstract

The invention discloses a 3D model slicing processing method and device. The method comprises the steps of acquiring a 3D model; obtaining a plurality of cutting intersecting lines according to preset slicing parameters and the three-dimensional model; the cutting intersection line is a line segment where the surface element of the three-dimensional model intersects with the cutting surface; determining a direction reference quantity according to the target normal direction and the target cutting intersection line; the target normal direction is the normal direction of any surface element, and the target cutting intersection line is the cutting intersection line of any surface element; determining a cutting area according to the direction reference quantity and the vector direction of the plurality of cutting intersecting lines; and generating a slicing result according to the cutting area and the three-dimensional model. According to the method, the calculation overhead of the whole slice processing process can be greatly reduced, and the slice processing efficiency is remarkably improved.

Description

technical field [0001] The invention relates to the technical field of computer graphics, in particular to a 3D model slice processing method and device. Background technique [0002] With the continuous expansion and vertical integration of the application field of computer graphics, the 3D model processing algorithm is also constantly updated and iterated. Among them, the slicing algorithm is a tool that can be applied to most mainstream application scenarios such as 3D model analysis, visual art, 3D printing, etc., and its update and optimization will be very meaningful. However, currently, when slicing a 3D model, it is necessary to judge the direction of the intersection line between the cutting surface and the surface element of the 3D model. In the prior art, multi-conditional judgments are required to determine the intersection direction in the end. This judgment method has a large amount of calculation, which leads to low slice processing efficiency. Contents of...
