We present an architecture for remote visualization of datasets over the Grid. This permits an implementation‐agnostic approach, where different systems can be discovered, reserved and orchestrated without being concerned about specific hardware configurations. We illustrate the utility of our approach to deliver high‐quality interactive visualizations of medical datasets (circa 1 million triangles) to physically remote users, whose local physical resources would be otherwise overwhelmed. Our architecture extends to a full collaborative, resource‐aware environment, whilst our presentation details our first proof‐of‐concept implementation.
