OpenGL features and specs

• Cross-platform Compatibility
  OpenGL is platform-independent, allowing developers to write code that can run on multiple platforms such as Windows, macOS, Linux, and others without modification.
• Wide Hardware Support
  Extensive support across a broad range of graphics hardware, making it a reliable choice for ensuring that applications will work on various devices.
• Open Source
  As an open-source graphics API, OpenGL allows for extensive collaboration and contributions from the community, improving its features and performance over time.
• Industry Standard
  Used widely in the industry for professional applications in areas like CAD, virtual reality, and video games, providing good community support and documentation.
• Rich Feature Set
  Provides a comprehensive set of features for rendering 2D and 3D vector graphics, offering flexibility for developers to create complex visual effects.

Possible disadvantages of OpenGL

• Complexity
  OpenGL's vast array of features and options can lead to a steep learning curve for new developers who may find it challenging to implement even basic tasks.
• Obsolete Features
  Some parts of OpenGL are considered outdated, with legacy functionality that may complicate development and require additional effort to modernize older codebases.
• Performance Overhead
  While generally efficient, OpenGL can introduce overhead compared to lower-level APIs like Vulkan or Direct3D, which offer more direct control of graphics hardware resources.
• Fragmented Support
  Different platforms and graphics card vendors may implement OpenGL features inconsistently, requiring extra testing and potentially platform-specific workarounds.
• Low Abstraction
  Despite its flexibility, OpenGL provides a lower level of abstraction compared to some newer APIs, meaning that developers must manage more of the graphics pipeline manually.

Allegro features and specs

• Cross-Platform Support
  Allegro supports multiple platforms, including Windows, macOS, Linux, iOS, and Android, allowing developers to create applications that work across diverse systems.
• Open Source
  Being open source, Allegro is free to use and modify. This encourages community involvement and ensures continuous improvement and adaptability to user needs.
• Comprehensive Documentation
  Allegro offers extensive documentation and numerous tutorials, making it easier for beginners to learn and for seasoned developers to find solutions to specific problems.
• Strong Community Support
  The library is backed by an active community of developers who contribute to forums and resources, providing assistance and sharing knowledge.
• Simple API
  Allegro features a straightforward and easy-to-understand API, making it accessible for beginners and allowing for rapid development of 2D games and multimedia applications.

Possible disadvantages of Allegro

• Limited 3D Support
  Allegro is primarily designed for 2D graphics, and while it can handle basic 3D rendering, it is not as robust or feature-rich as dedicated 3D engines.
• Lack of Advanced Features
  Compared to larger game engines, Allegro lacks certain advanced features like complex animation tools and integrated development environments, which may limit its use in high-end game development.
• Smaller Ecosystem
  The ecosystem around Allegro is smaller compared to other well-established frameworks and engines like Unity or Unreal, leading to fewer third-party tools and plugins.
• Performance Limitations
  While suitable for simple games and applications, Allegro might struggle with performance optimization and efficiency in very resource-intensive or complex projects.
• Dependency Management
  Setting up Allegro and its dependencies can be challenging for newcomers, requiring familiarity with C/C++ build systems and package managers.
