Figure 1: Production pipeline of stroke-based buildings. The edges of facade images are extracted and vectorized. This vector data is used instead of textures to represent the facade in the final 3D model.
AbstractIn this paper, we present a new approach for remote visualization of large 3D cities. Our approach is based on expressive rendering (also known as Non-Photorealistic Rendering), and more precisely, on feature lines. By focusing on characteristic features, this solution brings a more legible visualization and reduces the amount of data transmitted on the network. We also introduce a client-server system for remote rendering, as well as the involved pre-processing stage that is required for optimization. Based on the presented system, we perform a study on the usability of such an approach in the context of mobile devices.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
