OpenGL by Rexo Web — a deep editorial

OpenGL is one of the foundational APIs of real-time 3D graphics. When a modern web‑focused studio like Rexo Web approaches it, the result is more than technical how‑to; it’s a point of view about how low‑level graphics, web delivery, and creative intent intersect. This editorial looks at the technical lineage, practical tradeoffs, and artistic implications of using OpenGL in a web context, and considers what Rexo Web’s focus reveals about the evolving relationship between native graphics APIs and the web platform.

OpenGL vs. The New Guard (Vulkan & DirectX 12)

In recent years, new APIs like Vulkan and DirectX 12 have emerged, offering lower-level access to hardware and better performance. So, is OpenGL dead? OpenGL by Rexo Web — a deep editorial

Absolutely not.

While Vulkan offers more control, it is significantly more complex to implement and requires writing much more code ("boilerplate"). OpenGL remains the preferred choice for: Introduction: OpenGL vs
