Abstract:
Supporting decision processes via fast and accurate visualization of 3D data is an important aspect in many scientific fields, ranging from mathematics and engineering trough medical data analysis. Due to their high flexibility and platform-independence, 3D Web technologies have become more and more important for such visualization purposes. Within this paper, we concentrate on the accurate rendering of 3D surface models inside Web browsers and show efficient techniques that enable fast and precise visualization and interaction using state-of-the-art Web technologies. We introduce a smart vertex data storage format, which fits very well with the requirements of modern mobile graphics hardware. Furthermore, we discuss methods to partition models of high complexity. Finally, we present an hardware-accelerated picking algorithm that enables a high precision inspection of 3D objects and their vertex attributes.
