VirtualGL

VirtualGL enables the display of OpenGL applications on remote X servers by intercepting rendering calls and forwarding the resulting frames to a client’s graphics hardware. It works with headless NVIDIA GPUs and supports integration with virtual X servers such as TurboVNC, allowing 3D and video workloads to be visualized on machines that lack a local display. The software is distributed as binaries and source tarballs, with package repositories for YUM and APT, and runs on macOS among other supported operating systems.

Typical users include researchers, engineers, and developers who need to run graphics‑intensive applications on remote or virtualized hardware while preserving interactive performance. By separating rendering from display, VirtualGL lets users leverage powerful server‑side GPUs without requiring a physical monitor, facilitating remote visualization, collaborative work, and resource‑constrained environments.

The project is maintained as a stable, open‑source codebase under a Creative Commons Attribution license, and it provides documentation, mailing lists, and continuous‑integration builds. It is often paired with TurboVNC and libjpeg‑turbo to deliver high‑speed virtual X sessions and efficient JPEG encoding for transmitted frames.
