Android supports OpenGL ES for 3D rendering. OpenGL ES is a subset of the desktop OpenGL API implementation. On its own, Open Graphics Library (OpenGL) is a very popular cross-platform API for rendering 2D and 3D graphics.
It is slightly more complex to use OpenGL ES to render our custom view than the standard Android canvas drawing primitives and, as we'll see during this chapter, it needs to be used with common sense and it won't always be the best approach.
For any additional information about OpenGL ES please refer to the official documentation from The Khronos Group:
