Surfaceview's black background blocks the parent's background, and now sets the surfaceview background to be transparent, seeing both the 3D object being painted and the background.In onsurfacecreated, call Gles20.glclearcolor (0f, 0f, 0f, 0f); Alpha is 0, which is transparent.Then, the Surfaceview must be treated as follows:Mglsurfaceview.seteglconfigchooser (8, 8, 8, 8, 16, 0);Testrenderer renderer = new

Create a DrawLine Activity that defines four vertices:float vertexarray[] =-0.8f,-0.4f1.732f0.0f- 0.4f0.4f1.732f0.0f0.0f,-0.4f1.732f 0.0f0.4f0.4f1.732f0.0f,};Draw the line in three modes Gl_lines,gl_line_strip,gl_line_loop, respectively: Public voidDrawscene (GL10 gl) {super. Drawscene (GL); Bytebuffer VBB= Bytebuffer.allocatedirect (vertexarray.length*4); Vbb.order (Byteorder.nativeorder ()); Floatbuffer Vertex=Vbb.asfloatbuffer (); Vertex.put (Vertexarray); Vertex.position (

Shader is an important part of OpenGL ES.Brief introductionThe shader program is a program that runs on the GPU and is a program written in GLSL language.FunctionWith OpenGL shaders, you can enrich rendering, and the features you can implement include:(1) More authentic materials-metal, stone, wood, etc.(2) More realistic lighting effects-area lighting, soft shadows, etc.(

its local coordinate system (T). At this time, the order of the Code is the same as that of the local coordinate system relative to the object. GL. glmatrixmode (gl_modelview); By using the object's local coordinate system, you can better understand graphics systems such as robots and the solar system. The glulookat sub-function of the glulookat package of Android OpenGL

The ondrawframe modification code is as follows: public void onDrawFrame(GL10 gl) { // Clears the screen and depth buffer. gl.glClear(GL10.GL_COLOR_BUFFER_BIT | GL10.GL_DEPTH_BUFFER_BIT); // Replace the current matrix with the identity matrix gl.glLoadIdentity(); // Translates 10 units into the screen. gl.glTranslatef(0,
