+  summary: VirtualGL optimizes remote application performance by intercepting and redirecting OpenGL commands for smoother graphics rendering.
+  description: |
+    VirtualGL is a versatile toolkit that optimizes the graphical performance of applications running remotely on a server but displayed locally on a client machine. By intercepting OpenGL commands from the remote application and directing them to the client for rendering, VirtualGL enhances responsiveness and efficiency, particularly for graphics-intensive tasks like CAD, scientific visualization, and gaming. This technology enables smoother, more responsive user experiences in remote computing environments by reducing network bandwidth requirements and ensuring high-quality graphics output.
