## Question

What are the applications of OpenGL (application of OpenGL in computer graphics)?

## Short answer

OpenGL is used for hardware-accelerated 2D and 3D graphics in many fields. It powers computer games, CAD/CAM engineering design, animation and special effects, virtual and augmented reality, scientific and medical visualization, simulators, GIS, mobile interfaces, and educational graphics.

## Answer

OpenGL is used wherever 2D or 3D graphics must be drawn fast with hardware support:
1. **Computer games** and game engines.
2. **CAD/CAM and engineering design:** 3D modelling of machines, buildings and circuits.
3. **Animation and film special effects.**
4. **Virtual reality and augmented reality.**
5. **Scientific and information visualisation:** simulations of weather, molecules, graphs.
6. **Medical imaging:** 3D display of CT and MRI data.
7. **Simulators:** flight and driving simulators.
8. **GIS and mapping**, and architectural walkthroughs.
9. **User interfaces and mobile graphics** (OpenGL ES in phones and embedded devices).
10. **Education** and graphics teaching.
