WebGL vs OpenGL | Know The 6 Most Useful Differences

Difference Between WebGL vs OpenGL

WebGL is abbreviated as Web Graphics Library. It is mainly designed for rendering two-dimensional graphics and Interactive three-dimensional graphics. It is Javascript API that can be used with HTML5. It supports cross-platform and it is available in the English language only. The WebGL programs consist of a control code that is written in JavaScript. OpenGL is called as Open Graphics Library. It is referred to as a cross-language and platform application programming interface for rendering the two dimensional and three-dimensional vector graphics. OpenGL provides many functionalities like extensions.

Let us study much more about WebGL vs OpenGL in detail:

The original author of WebGL is Mozilla foundations but it was developed by the Khronos WebGL Working group. It was initially released in the year 2011. There are many advantages of using WebGL, as WebGL applications are written in javascript, with the help of these applications there can be direct interaction with other elements of the HTML document. It provides support to all browsers and mobile browsers as well as IOS safari, android browser, etc.
WebGL is open-source and can access the code easily. There is no need to compile the code for WebGL applications. WebGL supports automatic memory management, there is no need of manual memory allocation. There is no need for additional setup and for developing the web application text editor and browser is required only.
OpenGL API is used to interact with GPU (graphics processing unit) to get the hardware-accelerated rendering and OpenGL applications mainly used in the computer-aided design, virtual reality, visualization, video games, etc.
The original author of OpenGL was Silicon Graphics. It was developed by Khronos Group. It was initially released in the year 1992 and it was written in the C language. OpenGL commands or shaders are written GLSL like vertex, geometry, fragment, etc. In OpenGL, there is a fixed-function pipeline which makes it better for developers to use this for web applications.

Key Differences between WebGL vs OpenGL

Both WebGL vs OpenGL are popular choices in the market; let us discuss some of the major Difference Between WebGL vs OpenGL :

WebGL is based on OpenGL ES which lacks the many features that regular OpenGL is having like it supports only vertex and fragment shaders. OpenGL has features that are not in WebGL like geometry shaders, tessellation shaders, and compute shaders.
WebGL is mainly used for browsers. OpenGL do need native drivers and is mainly oriented to install software.
WebGL is used for web applications and OpenGL is used for many video games.
WebGL is easier to learn and develop the applications. OpenGL can be learned easily, if once you are familiar with WebGL.
In WebGL, it can fake 3D texture with help of using 2D texture. In OpenGL, it is not required to do as it has a lot of features like geometry and shaders.
In WebGL, it is forced to learn use shaders and buffers from the start. In OpenGL, it is not like that.
WebGL has less learning curve as it has fewer features. OpenGL has a bigger learning curve as it is having a lot of features including WebGL has.
WebGL is based on OpenGL ES 2 which is not plain OpenGL. OpenGL ES is the subset of OpenGL. OpenGL ES has fewer capabilities and is very simpler to a user. OpenGL has lot capabilities and difficult to use.

Conclusion – WebGL vs OpenGL

OpenGL vs WebGL both are graphics library to render two dimensional and three-dimensional graphics. WebGL is being used in HTML canvas element, it means can be incorporated with HTML language. WebGL is easy to learn as it is simple and easy to use in javascript and Html. OpenGL does require good knowledge to work with and develop the application.

Both OpenGL vs WebGL are having advantages and disadvantages. The selection of graphics library can be done on the basis of requirements, scalability and future vision for the application. It means it is always necessary to learn, explore and use the different technologies to develop and upgrade the skill set.
