Embodiment Construction

[0032] The method of the present invention will be described in detail below through embodiments in conjunction with the accompanying drawings.

[0033] The present invention is a modeling method based on convolution surface approximation in a VR environment, which includes selecting one of the three skeletons of points, lines, and surfaces and setting the size and thickness, inputting the skeleton through the buttons of the VR handle, and passing the touch on the handle. Swipe in the x or y direction on the control board to change the size, thickness and direction of the brush, use the convolution surface to approximate the point, line, polygon skeleton with radius information, and the system transfers the obtained input skeleton to the GPU for processing The parallel field calculates and extracts the isosurface; the specific steps are as follows:

Abstract

The invention provides a modeling method based on convolutional curved surface approximation in the VR environment. The method comprises steps that one type of point, line and plane frameworks is selected, sizes and thickness are set, the data is inputted to the framework through a button of a VR handle, a convolutional curved surface is utilized to carry out approximation of the point, line and plane polygon frameworks having the radius information, the acquired input framework is transferred to a GPU through a system to carry out parallel field calculation and extract contour surfaces. The method is advantaged in that problems of complex operation caused by modeling generally based on two-dimensional planes in a 3D modeling tool in the prior art and mismatching between modeling input sizes and output model sizes in the VR are solved, a convolutional curved surface approximation method based on the frameworks is utilized, for approximation of the different-diameter frameworks inputted by users in an interaction system, closed solution schemes are derived respectively for line segment framework tail ends and polygon framework edges. Moreover, for various complex shapes, different humanized coating schemes are provided for simplified input.

Description

technical field [0001] The invention relates to the fields of virtual reality and computer graphics modeling, in particular to a modeling method based on convolution surface approximation in a VR environment. Background technique [0002] 3D modeling technology is mainly to establish a model with three-dimensional data in a virtual three-dimensional space, which can be applied to various fields of design, architecture, industry and animation. The 3D modeling technology for 3D printers allows users to print out the built models at any time, but only solid models with 2D manifold surfaces can be physically manufactured or 3D printed. It is for this reason that even if 3D printers are not Very expensive, and few consumers are willing to buy it. [0003] Professional 3D modeling tools include 3DMAX, MAYA, ZBRUSH, etc., but these professional 3D modeling tools are too complicated for ordinary users without professional skills, and in these software, it is difficult to ensure tha...
