It should be noted that, the 3D figure drawn by OpenGLSurfaceView by ShowSTL class is shown.
For the ease of understanding, be described in detail implementation embodiment illustrated in fig. 2 below, application examples comprises:
First two java classs are set up: one is OpenGLRender, and he directly realizes android.opengl.GlSurfaceView.Render interface, and another is OpenGLSurfaceView, and he directly inherits android.opengl.GlSurfaceView class.In order to realize the display of 3D model and can adjust 3D model (amplify, reduce, horizontally rotate, vertical rotary).Also to design a ShowSTL class, its direct succession of this class and android.app.Activity and the interface realizing android.view.View.OnClickListener.
Next the class designed above is described:
OpenGLRender class: this class mainly carries out the drafting of 3-D view, and graphics process (such as Scalable, rotate), the drafting of 3-D view is mainly in the onDrawFrame () function of father's interface of its realization, set OpenGL graphic plotting option, draw the data coming from stl file, thus realize the display of three-dimensional picture.For graphics process (Scalable rotates).OpenGLES does not provide such function, team writes algorithm realization by oneself, concrete thinking: by the GLU.gluLookAt () function of OpenGLES, the three-dimensional position changing the observation point camera (concept in OpenGL) of image realizes rotation and the Scalable of figure, such mode not only reduces the data operation of flood tide, and accelerates the fluency of display of 3D rendering.
3-D view Rotation Algorithm java key code:
//Z_X_camera and Z_Y_camera is the z-axis data that each spinning produces,
//Z_camera is common z-axis data;
if(isX＝＝true)
{
X_camera＝(float)((RotateRadius+mytriangle.fangdasuoxiao)*Math.sin(angle*Math.PI/180))；
Z_X_camera＝(float)((RotateRadius+mytriangle.fangdasuoxiao)*Math.cos(angle*Math.PI/180))；
Z_camera＝(float)((RotateRadius+mytriangle.fangdasuoxiao)*Math.cos(angle*Math.PI/180))；
}
else
{
Y_camera＝(float)((RotateRadius+mytriangle.fangdasuoxiao)*Math.sin(angle*Math.PI/180))；
Z_Y_camera＝(float)((RotateRadius+mytriangle.fangdasuoxiao)*Math.cos(angle*Math.PI/180))；
Z_camera＝(float)((RotateRadius+mytriangle.fangdasuoxiao)*Math.cos(angle*Math.PI/180))；
}
OpenGLSurfaceView class: this kind ofly mainly carry out screen touch event handling, and the setting of graph rendering pattern.Touch mainly processes inner the adding of member function onTouchEvent () of inheriting parent by screen touch event handling, realization approach is: the distance (level of sliding at screen according to user's finger, vertically), they are converted into the anglec of rotation of 3D rendering, then these angles rotated are used for the image rotation processing method of OpenGLRender class.
First by obtaining the length of user mobile phone screen, wide, then calculate image in their unit lengths carry out 360 degree rotate time the unit anglec of rotation, that's all, such as 360/180=2 represents that width is the screen 3D rendering rotation 2 degree of 180, and the distance of finger movement is in the horizontal direction 1.
Method is below the java key code of the disposal route for the different moving direction of 3D model.
OpenGLSurfaceView class inherits this class of android.opengl.GLSurfaceView.OnTouchEvent () method inside this class of its heavy duty.Being implemented as follows of the method:
ShowSTL class: the 3D figure mainly shown OpenGLSurfaceView draws shows, the adjustment function of simultaneously adding 3D model (is amplified, reduce, horizontally rotate, vertical rotary) interactive interface, the storage of some state flag bits relied on during most important auxiliary 3D models show and detection, such as, click model large buttons, the value of the display multiple of amendment current Graphics, during for 3D modeling rendering.Again such as, record current whether click and move horizontally or the button of vertically movement, it is an enable effect in fact.The display adjusting method of 3D model depends on the various status informations of whole class record very much.
The value of the value mytriangle.fangdasuoxiao of the 3D models show multiple that the graphical interaction interface (button) of being recorded by class ShowSTL is revised, (level is rotated at 3D model, vertically) in algorithm java key code, the called position of the camera visual angle point inside OpenGL that makes produces far and near effect, thus reaches the method for adjustment of 3D model Scalable.
In the present embodiment, by carrying out the real-time conversion of the anglec of rotation based on coordinate axis to 3D model according to adjustment track, rotate processing mode according to the anglec of rotation according to prediction picture again to process, obtain the observation point camera three-dimensional space position that the 3D model after process is corresponding, the finally real-time 3D model graph rendering process carrying out correspondence according to observation point camera three-dimensional space position, just the adjustment by carrying out 3D model at mobile terminal is achieved, the printing that 3D printer carries out 3D model is triggered again after making direct vision 3D model, solve current mobile phone and be all connected Cloud Server by wireless network with 3D printer, user is controlled and on-line selection three dimensional model printing by mobile phone remote.After the three-dimensional model chosen is cut into slices to 3D model by Cloud Server, re-send in 3D printer and print, can only be controlled and on-line selection three dimensional model printing by mobile phone remote, the rotation needing the 3D model printed cannot be carried out in mobile phone, amplify, the operation intuitively browsed such as to reduce, and the technical matters that the experience property caused is low, and by the GLU.gluLookAt () function of OpenGLES, the three-dimensional position changing the observation point camera of image realizes rotation and the Scalable of figure, such mode not only reduces the data operation of flood tide, and accelerate the fluency of display of 3D rendering.
