Abstract

The invention is applicable to the field of image processing, and provides with a method and a device of rendering a 3D (three dimensional) model in any orientation. The method comprises the steps of obtaining the primary position and the primary direction vector of the last moment of the 3D model and the target position and the target direction vector of the 3D model through a 3D interactive tool; calculating the rotary matrix of the 3D matrix through the primary direction vector and the target direction vector, and calculating the translation matrix of the 3D model through the primary position and the target position; calculating the control matrix of the 3D model through the rotary matrix and the translation matrix; substituting the primary 3D data point information of the 3D model into the control matrix to obtain the target coordinates and target directions of all points of the 3D model, and rendering the target 3D model. Any 3D model which accords with a control requirement can be rendered, so that the method is applicable to the real-time rendering of any 3D model, the speed of determining the position of the 3D model can be improved in real time, and the state of controlling the 3D model can be effectively improved.

Description

technical field [0001] The invention belongs to the field of image processing, in particular to a method and device for rendering a 3D model in any orientation. Background technique [0002] With the continuous development of computer graphics and virtual technology, 3D technology has been widely used in various fields, and the application requirements of 3D models are increasing. With the expansion of demand, the requirements for 3D models are getting higher and higher, and the requirements for freely controlling the rendering of 3D models according to control conditions are gradually becoming stronger, especially for interactive 3D models. Freely control rendering according to control conditions is in urgent need of application. The 3D model is generally composed of many 3D data points, which are generally prepared in advance, and it is difficult to quickly and real-time generate a new 3D model of any orientation required by the controller according to the controller's nee...
