How to raise OpenGL level on Android without GLtool
Hello, friends if you want to change the OpenGL ES level
So you need to follow the steps.
To extend OpenGL, you first need root access to your phone.
You will then need a root browser to access the root directory
And then
Go
System folder in the root directory
After that, there you can see a file call build.prop
You need to edit that file.
You need to add a line
ro.opengles.version = 331072
After adding that line you need to save that file and reboot your phone.
And then you can test the OpenGL ES version by CPU-Z
.................................................. .................................................. .................................................. .................
(requires root access to edit build.prop)
- build.prop code -
ro.opengles.version = 331072
........................................................
The central processing unit on your computer can do just about anything. But even the craziest computers' CPUsonly has about eight cores these days which isn't enough to render the complex scene in real-time. Fortunately,
your computer and phone also have to say, graphics processing unit, or GPU. GPUs are chips purpose-built to pump out pixels, and some can have thousands of cores. Each of these cores is pretty limited in what it can do, though, and groups of these cores have to work together in lockstep, each executing the same instructions each clock cycle.
So while the GPU is less flexible than a CPU, it can spew out pixels at some absurd rate.
So the code we run on the CPU determines what we want to draw. And then we send those instructions over to the GPU which will actually figure out the pixel colors.
To do this we need a language for communicating between the CPU and the GPU. The most common language for this purpose is called the Open Graphics Language or OpenGL.
Smartphones use a slightly scaled-down version of this language called OpenGL ES, where the ES stands for embedded systems. If in a Microsoft universe you've ever heard of DirectX, that's a language that serves essentially serves the same purpose.
So to sum up the CPU uses OpenGL to tell the GPU what to draw. The GPU builds up the actual array of colors and ships it to the electronics that run the screen. Brief aside,
I'd be failing as a nerd if I didn't mention that you can actually do far more with GPUs than just color pixels. There's a whole field of general-purpose GPU computing.
Algorithms that run on GPUsneed to be very clever about how they get those lock-stepping cores to work together. But when they do, they can be extremely fast, and as is often even more important these days, extremely energy efficient in terms of power per calculation.
Is OpenGL worth learning? It is not worse than the main rival, DirectX. Why would I want to learn OpenGL?
OpenGL is probably a necessity if you want to work on 3D games. And you have to know it to do 3D games for Mac, Linux, and other-Microsoft OS.
I’d be good to learn the basis of 3D gaming, given how that’s the future of gaming. You probably need SFML. LOL. What is SFML? SFML stands for Simple and Fast MultimediaLibrary. It lets you use accelerated 2D graphics with OpenGL. I’ve heard of SDL.
SDL stands for Simple DirectMedia Layer. SDLcontrols the input devices like the game controller and outputs like the sound card. What’s another reason to know OpenGL? If you know OpenGL, you’ll have a better understanding of Web GL.
That’s like Ruby on Rails, a former programming star language, or Groovy, a wannabe cool language. If you don’t want to learn OpenGL, you could create those cute little Adobe Flash games that everyone hopes become addictive and sella million one-dollar downloads. Until Adobe Flash is declared officially dead.
Which version of OpenGL should I learn?
Don’t limit yourself to a particular OpenGL version. I would think the latest and greatest would be best to know if I’m going to put it on my resume and compete in the job market.
The latest and greatest OpenGL version isn't mature, whereas there are plenty of games in the prior one. And in the worst-case scenario, I can get paid to upgrade older games to the latest OpenGL version.
There are still people playing video arcade games from the 1970s and 1980s. On smartphones that didn’t exist five years ago! And are smarter than the PCs of ten years ago! At least you know OpenGL is good for game development for the next ten years.
Should I learn Unity or OpenGL?
OpenGL is a low-level operating system interface so you can write code and determine the best way to control the hardware, such as the soundcard or video card. I've heard the library in OpenGL figures out the best way to do what you're asking the hardware to do. OpenGL is an API. It does not do as much asUnity. Then I should learn Unity. Unity is a game engine. It lays on top of libraries like OpenGL or DirectX.
One of the advantages of using Unity is that it is an all in one tool. That's probably where the name comes from. Unity is a whole development suite, not just a library of parts to put together or a framework to help make sure they all fit. You can create the whole game in Unity. I've heard you can create games in OpenGL, though it is less productive.
Use OpenGL along with OpenCL as a full alternative to Unity for creating your own games. Then I just need to learn Unity to get into gaming.
If you are working in Unity, you should knowC# or JavaScript, too. It's never that easy. But I like the idea of using a game engine that makes it as simple as possible to create games. But you give up control. It is like giving up the convenience of controlling interfaces and background designs for the plug and play options of WordPress. So what should I learn?
Unity does far more than OpenGL. For example, it can handle game levels and inputs in addition to figuring out how to render your backgrounds and play music. I think I should learn Unity, if only for the all in one nature.
Unity, AKA UDK, is a Game Engine. That makes it a good starting point for game development. I'll learn OpenGL later if I have to start to understand what's under the hood after I start my driving lessons. Or need to learn how to fix the engine after you've crashed it a few times.
