:// Create a framebuffer var fb = gl.createframebuffer (); // bind FB as the current window Gl.bindframebuffer (GL. FRAMEBUFFER,FB);In this way, we create a new buffer that can be drawn, and it is not displayed.But will that be all right? The idea is to render the texture after the shader rendering and hand it over to the next shader, when the method is introduced framebuffertexture2d Reference from "OpenGL ES Reference Pages about Framebuffert

geometric images. In Android, SurfaceView is generally used to draw 2D images, while GLSurfaceView is used to display 3D OpenGL views, and 3D images are rendered through the Renderer interface. Therefore, we first establish a class that implements the Renderer interface. The Code has a detailed note: [java] public class GLRender implements Renderer {private float rotateTri; private int one = 0x10000; // a vertex of the triangle private IntBuffer triggerBuffer = BufferUtil. fBuffer (new int [] {

Examples of use of >texparameteri Gl.texparameteri (GL

The most complete sysctl. conf optimization solution in China There are various versions of the sysctl. conf optimization solution on the Internet, most of which are copied and copied, making new users confused. In order to solve this problem, I have reviewed N materials over the past two days and summarized them as follows. Many default documents that do not need to be modified are not currently involved, in the future, we will gradually provide translation, explanation, and modification sugges

An application can explicitly specify the source IP address by applying bind (2) system calls to SENDMSG (2) calls and through a secondary data object ip_pktinfo. In this case, the operating system kernel simply checks to see if the source IP address is correct, or a corresponding error occurs. 2. If the application does not specify a source IP address, the routing table containing the source IP deter

(Draft only, not sorted) Chapter 2 2 OpenGL ES running 2.1 Basic Principle of OpenGL ES OpenGL ES (later called "Gl") is only concerned with rendering in the frame cache (and Reading saved values from the frame cache ). In some cases, peripheral devices related to graphic hardware, such as the mouse and keyboard, are not supported. Programmers must rely on other mechanisms to obtain input information, such as khronos openkodeapi. The basic elements o
