A real-time 3D clay modeling method based on stroke interaction

Abstract

The invention discloses a real-time 3D clay modeling method based on stroke interaction, which relates to the 3D modeling field. The invention comprises the following steps: S01, sampling the space point by point with equal spacing and recording each sampling point; S02, generating all voxels and edge elements in the space according to the sampling points; S03, sorting the coordinates of the elements according to the dictionary order and storing the coordinates to the balanced binary search tree; S04, constructing a spatial data structure and generating a model grid; S05, delimiting the influence region in the space and increasing or decreasing the potential function in the set region; S06, the influence region classifies the sampling points in the space; S07, discretizing the one-time drag into the displacement of a plurality of influence regions; S08, repeating the above steps to realize the interactive real-time deformation of strokes. The invention realizes the construction and storage of a model by adopting an implicit modeling method, generates a model surface by setting a space potential field to obtain a required isosurface, and easily completes the contact and fusion between materials without considering the topology of the surface.

Description

technical field [0001] The invention belongs to the field of 3D modeling, in particular to a real-time 3D clay modeling method based on stroke interaction. Background technique [0002] Design has been an important part of human civilization since ancient times. Every object invented by human beings, from airplanes and high-speed rails to toothbrushes and mobile phones, cannot be separated from design before it is put into production. With the development of modern society, digital 3D model design using computers has gradually become an indispensable part of human work and life. From house modeling design in the architectural field, CG production in the film field, to virtual character modeling design in the game field and the construction of various item and prop models, an excellent digital modeling method has played a pivotal role in all of them. In the current field of digital modeling, most interactive modeling methods achieve the effect of generating volume by squeezi...
