Problems solved by technology

However, we found that no matter how powerful the tool is, users always use the mouse and keyboard to draw the 3D model, lacking a more intuitive drawing method, and it is very complicated. For people who do not have a strong sense of space, Drawing three-dimensional stereograms is undoubtedly the most troublesome

Embodiment Construction

[0027] like figure 1 as well as figure 2 As shown, a three-dimensional model rendering system includes a sensor glove 110 , a magnetic tracking device 120 , an optical see-through display helmet 130 and a data processing device 140 .

[0028] The five fingers of the sensing glove 110 are equipped with curvature sensors 111. When the fingers are bent, the resistance of the sensors will become smaller. Through the bending readings of different sensors on the five fingers and their combinations, we can identify the current position of the user. gesture.

[0029] The magnetic tracking device 120 includes a magnetic sensor 121 and a magnetic emission source 122. The magnetic sensor 121 is arranged on the sensing glove 110. When the sensing glove 110 moves, the distance between the magnetic sensor 121 and the magnetic emission source 122 will change, thereby generating According to the change of the magnetic force intensity, the coordinates of the hand used for drawing in space c...

Abstract

The invention discloses a drawing system for a three-dimensional model. The drawing system comprises a sensing glove, a magnetic tracking device, an optical perspective display helmet and a data processing device, wherein each of five finger parts of the sensing glove is provided with a curvature sensor; the magnetic tracking device comprises a magnetic sensor and a magnetic emission source; the magnetic sensor is arranged on the sensing glove; and the curvature sensors, the magnetic sensor, the magnetic emission source and the optical perspective display helmet are all connected to the data processing device. The drawing system is simple in structure and convenient to operate; a user can directly draw a model which the user wants to create in a three-dimensional virtual space by utilizing two flexible hands; in comparison with the existing manner, the drawing system is more efficient and convenient, and breaks a restriction that the three-dimensional model is only created on a two-dimensional plane, so that the user can draw a graph in a space more directly.

Description

technical field [0001] The invention belongs to the field of drawing, and in particular relates to a three-dimensional model drawing system and a drawing method thereof. Background technique [0002] Drawing three-dimensional graphics is usually only done with the help of three-dimensional drawing software in the computer. [0003] In recent years, with the vigorous development of 3D drawing technology, various 3D drawing tools such as 3DsMax, AutoCAD, etc. are constantly being introduced, and their functions are becoming more and more powerful. However, we found that no matter how powerful the tool is, users always use the mouse and keyboard to draw the 3D model, lacking a more intuitive drawing method, and it is very complicated. For people who do not have a strong sense of space, Drawing three-dimensional stereograms is undoubtedly the most troublesome. Contents of the invention [0004] Based on this, aiming at the above technical problems, a three-dimensional model ...
