OpenGL ES has functions used to operate graphics rendering pipelines. By default, these functions are disabled. To enable and disable these functions, you can use glenablec

. Learn about 2D. Let's take a look at the 3D drawing method. 3D drawing SDK is very simple. It just introduces a general method, that is, inheriting a View, and then obtaining the Opengl handle in this View for drawing, it should be the same as 2D. The difference is that 2D APIs are used for drawing, and 3D is used for drawing. However, because 3D openGl | ES ha

tablet size (1024x768) or any other device with the same screen, we can use software simulation to scale, but it will be slow and intolerable. To scale in a hybrid mode, you need to create an OpenGL ES texture and render the image (320x240) to the GL quadrilateral.Textures are scaled to the appropriate display size (1024x768) through hardware, significantly improving game performance.From the implementatio

running in a thread that is independent of the main threads, you must declare the parameter to be volatile: Public class Myglrenderer implements Glsurfaceview.renderer {...public volatile float mAngle;public float Getangle () {return mAngle;}public void Setangle (float angle) {MAngle = angle;}} 3.

In fact, the main purpose of my personal study of Android is to learn how to develop 3D effects on this platform. So let's start with the topic. OpenGL ES (OpenGL for Embedded Systems) is a subset of OpenGL 3D graphics APIs. It is designed for Embedded devices such as mobile phones, PDAs, and game hosts.This API was d

'd like to tell you that people use cameras to observe things in 3D, although OpenGL does not actually have a camera. So when you move on the screen, you are actually moving all objects, and the feeling of motion is not caused by the creation of a camera to watch movies, instead, all objects in the world are moved with the relative coordinates (0, 0. It sounds l

Recently, I came up with an idea on Android: how to use OpenGL ES to draw a 3D image in the background, and then save the drawn image as a bitmap format... After several days of thinking, I tried a variety of methods, but none of them worked. At first I tried the glsurfaceview method, but this would lead to a connection between my activity and the rendered stuff, the result I want is that in any case, my ma

. OpenGL ES is custom-tailored from OpenGL, removing many of the non-essential features such as glbegin/glend, quads (gl_quads), polygons (gl_polygons), and more. There are currently two versions, and OpenGL ES 1.1 is based on the OpenGL
