Abstract

One important aspect of semantic data in computer visualization is to offer supporting and extra information of the environment besides the pure graphical information to system users. It is devoted to help them understand the visualization result better. This paper presents a way to visualize semantic data in 3D urban environment in form of text, which is similar to the issue of 3D labelling and annotation. Different objects in 3D urban environment need different annotation techniques. Occlusions, overlaps, readability, visibility and information density are problems encountered frequently, and several potential solutions are proposed accordingly. A primary test is done to compare the performances among three different text layout techniques: floating text, fading text, linking text. The result shows that floating text and fading text are well understood in a 3D environment, the former one maintaining good readability and visibility and the latter one efficiently avoiding occlusions. Finally several open questions are proposed in the discussion part.
