While they are standards and could be theoretically implemented in any OS architecture, the reality is that DirectX is used only for Microsoft Windows (and XBOX, in case someone finds that information relevant). DirectX does not only cover graphics but also audio and input. I have not evaluated those ones as I do not consider them interesting for my needs.ĭirectX (Direct2D and Direct3D) is a set of APIs created by Microsoft which are implemented in Windows. Metal is focused on Apple devices and Vulkan intends to be an improvement over OpenGL. However, both DirectX and OpenGL are basically the most widely used ones. There are others, being the main ones Vulkan and Metal.

Major graphics cards manufacturers decide if their hardware devices will support one technology or the other or both (which is the usual case).ĭirectX and OpenGL are not the only standards/APIs that provide 2D and 3D rendering capabilities. Beyond the standards, there will be libraries implementing them, for DirectX libraries are provided directly by Microsoft and in the case of OpenGL, there are many open source solutions. In that sense, it is exactly the same as any other computing standard such as POSIX or the C++11 standard. It is important to understand that OpenGL and DirectX are hardware acceleration standards which define which APIs shall be exposed by graphics cards. There are two major competing standards in 2D and 3D acceleration: DirectX and OpenGL. The tutorial covers 2D, but it is actually a good introduction to OpenGL in general, so if you are interested in 3D, it is still good introductory material, as concepts are really similar for both 2D and 3D. In this post, I will briefly cover OpenGL and its usage in Java, including an introductory but completely useful tutorial. Relying on the main CPU for such tasks would imply that only less complex renderings could be done and that a lot of CPU time would be wasted to cope with the graphic routines.

It basically allows the software to draw complex graphics dealing with user coordinates, scaling, panning, zooming, rotations and texture rendering, both in 2D and 3D.īy providing such functionality close to the actual rastering output device, there is a reduction on both CPU usage and I/O bus bandwidth, which effectively enables to do complex renderings and animation, both in 2D and 3D. A GPU is a specific purpose CPU which provides the floating-point and matrices processing capabilities which are commonly used in 2D and 3D rendering. This is achieved by means of a specialised CPU (which is called GPU - graphics processing unit - ). While some graphics cards present more power and functionalities than others, a basic set of 2D and 3D acceleration is present in almost every modern device.

Hardware acceleration was once a high-end feature of specialised computers, such as Silicon Graphics UNIX workstations that were widely used in the film and TV industry during the 90s, but now it is a common feature present in every computer built during the last 15 or 20 years. Conventional charting tools and libraries are not fast enough for this task and hence custom graphics programming is needed. Hardware acceleration is often seen as a niche solution for game development, but there are many other graphical applications that can benefit from this technology, especially those involving data visualisation such as specialised data science tools or software displaying real time data.

Silicon Graphics workstations were used both in the movie and in the dinosaurs modelling and rendering process. In the photo, a film frame from “Jurassic Park”. They introduced IrisGL API (which is considered the direct father of OpenGL) and they were extensively used in movie and TV industry during the 90s. Silicon Graphics shined as a high-end 2D/3D graphics hardware-accelerated rendering workstation.
