With the tremendous advances in both hardware capabilities and rendering algorithms,
rendering performance is steadily increasing. Even consumer graphics hardware can render …

We discuss the significant technical challenges facing the CAD industry and research
community and present an approach to address these issues. The key component of all …

We present an external memory algorithm for fast display of very large and complex
geometric environments. We represent the model using a scene graph and employ different …

Due to its practical significance and its high degree of parallelism, ray tracing has always
been an attractive target for research in parallel processing. With recent advances in both …

We present a system for interactively producing exploded views of 3D architectural
environments such as multi-story buildings. These exploded views allow viewers to …

We present a novel approach for interactive view-dependent rendering of massive models.
Our algorithm combines view-dependent simplification, occlusion culling, and out-of-core …

One of the main objectives of the engineering departments of large industries is the
construction of integrated information systems to control their projects, offering resources for …

We propose a robust and imperceptible spectral watermarking method for high rate
embedding of a watermark into 3D polygonal meshes. Our approach consists of four main …

We present occlusion-switches for interactive visibility culling in complex 3D environments.
An occlusion-switch consists of two GPUs (graphics processing units) and each GPU is used …

A platform-independent occlusion culling library for dynamic environments, dPVS, can
benefit such applications as CAD and modeling tools, time-varying simulations, and …
