Method and device for real-time generation of network model by 3D brush based on leap Motion control

Abstract

The invention relates to a method and device for a three-dimensional brush to generate a network module in real time based on Leap Motion control. The method comprises the steps that the geometrical parameter of the three-dimensional brush is defined; the position of a frame handle of a current frame is captured as the position of the brush, and the density value and the normal vector of the vertex of a space lattice combined with the geometric parameter of the three-dimensional brush; if updating is needed, data which is newly calculated by the frame are written into current texture; texture data are read and the lattice is generated. According to the method, volume data in the moving process of the brush are captured through the hand position captured by Leap Motion and the geometric parameter of the three-dimensional brush, the dynamic volume data are subjected to network module visualization, the real-time interaction effect is achieved through GPU acceleration methods like rendering the volume data to the texture, and the advantages of being visible and efficient are achieved. The invention further discloses a device for the three-dimensional brush to generate the network module in real time based on Leap Motion control.

Description

technical field [0001] The invention relates to the technical field of human-computer interaction and volume data visualization, in particular to a method and device for generating a network model in real time with a three-dimensional brush based on Leap Motion control. Background technique [0002] With the increasing demand for 3D content, 3D modeling tools have been widely used after years of development, and there are also targeted solutions to the needs of different fields. However, there are still various deficiencies in the modeling mechanism and interaction level. [0003] The current interactive operation level of the modeling system is mainly divided into two types: parameter-based modeling and vertex-based modeling. The first modeling method is highly dependent on parameterization, so it is very suitable for highly regular and parametric mechanical and industrial production processes, but it is not suitable for the field of artistic creation, because artistic mode...

Problems solved by technology

These algorithms for creating 3D models from 2D sketches make the creation of 3D models more free to a certain extent, but now all model systems complete operations on 2D input media, resulting in 3D software. In order to complete input and output The cognitive correspondence of the medium can only correspond to the projection of the three-dimensional space to the two-dimensional screen and the dimension of the operation of the two-dimensional input device, so in a perspective angle, only two-dimensional operations are the most intuitive, and the result is The operation of a three-dimensional object is completed by frequently changing the angle of the window projection, or using some visual aids such as visually displaying the XYZ coordinate axes, and completing the operation of the corresponding dimension by clicking the coordinate axes in the illustration, so a full three-dimensional The most intuitive way to complete the cognition of three-dimensional operation
