In this paper, we illustrate the method of implementing OpenGL ES texture mapping in java. Share to everyone for your reference. Specifically as follows:

typeof nullAs object a result, this is actually typeof the one bug that is the null original value, the non-reference type
typeoof [1,2]As a result object , there is no such item in the result, and the reference type function is all but the object
typeof Symbol()With the typeof get symbol type of worth to be symbol , this is the ES6 new knowledge point

One, the expansion of the string The ES 6 strengthens support for Unicode. JavaScript allows a character to be represented in \uxxxxx, where xxxx represents the Unicode code point of the character. So there's a scope limit (\u0000 ~ \uffff).1. For ...The biggest advantage of this walker is that it supports code points larger than \uffff , which are not supported by traditional for loops.2. string.at (numberparam) and string.charat--it seems to be jus

Android uses ndk instead of yuv420 overlay to ensure smooth video display. Instead, it uses a platform to port a safer rgb565 display. Tested on Android 2.3.
However, the MTK andriod platform (a301) encountered a glteximage2d gl_error 0x501 error (the source image is 176*144 ). After repeated tests, this MTK andriod version supports OpenGL ES, but it has a strange limit on the resolution of the source image. When the source dimension width and height
Recently, due to interest, I began to learn OpenGL plotting. This article uses "Draw sphere" as a point to summarize what we have learned recently.
> OpenGL ES started with OpenGL from Android. As we all know, Android View is thread unsafe, so it is only allowed to operate on the View in the main thread. However, if we need to implement a complex interface, especially for game development, and draw a large number of images in the main thread, it will

=============== Problem description ====================
I want to learn the OpenGL ES technology after Android encapsulation, but I am not good at English. It is very difficult to read the official documentation. Therefore, I would like to ask you for help here.
I don't know how everyone learns this technology, or reading some good books or learning it by myself. I hope that the experts who understand th

You can analyze es stream files according to the MPEG standard.MPEG standard iso13818-2Es streaming was exported from an MPEG2 MPG file by a small program written by FFMPEG. Later, it was discovered that there were also ready-made extraction tools on the Internet.Write this program to better understand the es

OpenGL ES 3.0 Vertex coloring tool (1), opengles
OpenGL ES 3.0 Flowchart
1. Vertex Shader (Vertex Shader)
Vertex coloring implements a general programmable method for vertices.
The vertex shader inputs include the following:
• Shader program. Source Code or executable program of the vertex coloring program, which describes the operations to be performed on the vertex.
• Vertex shader inputs (or attributes)
The previous modelview transformation is equivalent to placing the camera and adjusting the position and angle of the object to be photographed. The projection transformation corresponds to adjusting the camera lens distance to obtain the scene.

Subsequent coordinate transformations are for the projection matrix. The purpose of projection transformation is to define the Viewing Volume. On the o
Many tutorials say that the cocos2d-x OpenGL ES World coordinate system origin is in the lower left corner, but as to why in the lower left corner no one has ever mentioned it, which leads most people to think that this is OpenGL ES's rule, in fact it is wrong, OpenGL The coordinate origin of ES in the lower left or center of the screen is related to the projection matrix, if we set the Cocos2d-x projectio
