Hierarchical, texture-based rendering is a key technology for exploring largescale data sets. We describe a framework for an interactive rendering system based on a client/server model. The system supports various output media from immersive 3-D environments to desktop based rendering systems. It uses web-based transport mechanisms to transfer the data between the server and the client application. This allows us to access and explore large-scale data sets from remote locations over the Internet. Hierarchical space-subdivision,wavelet compression, and progressive data transmission are used to visualize the data on the client side
