Simon iPhone-OpenGL ES tutorial-04 OpenGL ES 04-color and texture As my last tutorial said, I'm tired of drawing white objects on the screen, so that we can add some colors, just like the project automatically generated by the apple module. Next I will introduce you to pay attention to these concepts, because these concepts will work backwards (very fast) when we start texture rendering) In OpenGL

OpenGL ES Tutorial for Android-Part III-Transformations January 1st, 2010 by Per-Erik Bergman-Android,Embedded Last tutorial was about building your polygons. this tutorial is all about transformations, how to move the polygons around. I will continue this tutorial from where the previous ended so you can use that source code or make a copy of it. The previous tutorial details how to create a polygon. This tutorial describes how to move and transform

OpenGL ES 11-moving in 3D (TRANSLATOR: That. In fact, I jumped to another chapter, section 12, and learned how to judge an object in the 2D world, I think most of our game developers have already used huge peanut code, and it is easier to develop games in the 2D world. This chapter is of little use to us. So I am also lazy .) Bird flu, busy, Mother's Day, and other things mean that I am not here for a while. So now is the time to do things. 3D Movemen

OpenGL ES Tutorial for Android-Part VI-Textures December 30th, 2010Per-Erik Bergman-android,Embedded,Java Last Tutorial we worked a bit more on meshes and we have also talked about adding colors to our mesh. the most common way of adding colors to your mesh is to add a texture. there is a couple of different steps involved with adding a texture to the mesh IWill try to go through them all and explain the basics about them. In the previous tutorial, we

The digital signal actually transmits data streams. Generally, the data streams include the following three types: ES is the original code stream, and contains the continuous code streams of video, audio, or data. Ts is a transmission stream consisting of 188 bytes in a fixed length. It contains one or more programs with independent time bases and is suitable for environments with many error codes. We all know that the TS package starts with 0x47 and

My 1st OpenGL ES program for wince5 HTC touchhd Cheungmine After lunch, I had nothing to worry about. I looked at my cell phone (HTC touchhd) and suddenly wanted to compile an OpenGL program for fun. Download the OpenGL ES development kit from csdn. After decompression, several files are found in the bin/ARM/release directory: Libgles_cm.dll Libgles_cm.lib Libgles_cm.exp And so on. I'm going to copy libgles

It took four days to transfer an FPS game engine fly3d to OpenGL ES. As we all know, ES is intended for mobile devices, so for efficiency, it performs a lot of screening and subtraction on OpenGL, throwing away all inefficient functions such as (glbegin) and throwing away some of the drawn types such as gl_polygon, Here we will share with you the alternative method of using gldrawarray to draw polygon.And

I am not very busy recently. I plan to start learning OpenGL this week. There are already many books and materials on OpenGL on the Internet. The reason for writing is to develop a good learning habit and give a summary of your learning process. Basic Concepts OpenGL defines a cross-programming language and cross-platform programming interface specification. It is a high performance 3D graphics standard. OpenGL is a professional graphical program interface and is a powerful underlying graphics l

How to get partial field values in Es, by default, ES searches all fields of source, but sometimes we do not want to get all the field data, such as in development, we have dozens of fields in index, good dozens of g of data per day, all the return amount is too large.There are two ways to get the data for a specified field,1. Use the default method to find all the source data, and then filter the reorganiz

Mpegts Basics Look at these blog posts:Mpegts FoundationAnalysis of ts,pes,es structure of MpegtsTS Stream multiplexing and multiplexing is a reverse process. TS multiplexing gets the PES bare stream of audio and video. In general, the length of each TS packet is 188 bytes, and there is also a 204-byte, which is to add 16 bytes of Rs redundancy check information after each packet. In this case, the 188 bytes are analyzed, and the rest are similar.To i
