  • OpenGL's introduction of GLSL was much later, falling behind Direct3D's functionality.

OpenGL Stagnates

  • OpenGL's gap compared to Direct3D created a significant delay in development.
  • Direct3D 9.0 and 10.0 were released during that period, further pushing OpenGL into the background.
  • OpenGL's development shifted to the Khronos Group, a consortium of vendors for standards.

The New OpenGL (OpenGL 3.0+)

  • OpenGL 3.0 was released, keeping compatibility but falling behind in other features.
  • OpenGL 3.1+ removed immediate mode functionality and evolved to incorporate more modern features.

Deprecation, Core, and Compatibility Profiles

  • OpenGL 3.0 introduced the deprecation model to remove older features.
  • Core and Compatibility profiles provide flexibility and control when creating contexts.
  • Flag attributes (like "Core" or "Compatibility," "Forward Compatible," and "Debug") provide different contextual choices at runtime for the OpenGL API.

OpenGL 4.0

  • OpenGL 4.0 with the Core Profile and new features like tessellation.
  • The immediate mode API was eliminated, and any deprecated features were removed.

Portability and OpenGL ES/WebGL

  • OpenGL's cross-platform nature allows use on a number of systems (PCs, Macs, consoles, and mobile devices).
  • OpenGL ES is an embedded systems API, and WebGL is a web-based API extending the possibilities to the web browser.

Software and Hardware Pipeline

  • The software pipeline describes the process of creating graphical outputs.
  • The Application layer is the interface to OpenGL and other APIs.
