Trading for a currency pair on centralized crypto exchanges is organized via an order book, which collects all open buy and sell orders at any given time and thus forms the basis for price formation. Usually, the exchanges provide basic visualizations, which show the accumulated buy and sell volume in an animated 2d representation. However, this visualizationdoes not allow the user to compare different order books, e.g., several order book snapshots. In this work, we present OrderBookVis, a 2.5d representation that shows a discrete set of order books comparatively. For this purpose, the individual snapshots are displayed as a 2d representation as usual and placed one after the other on a 2d reference plane. As possible use cases, we discuss the analysis of the temporal evolution of the order book for a fixed market and the comparison of different order books across multiple markets.

This paper contributes an optimized web-based rendering approach and implementation for parameterized meshes used as 3d glyphs for information visualization. The approach is based on geometry instancing by means of instanced rendering in ***, and further allows for dynamic mesh selection according to a level-of-detail function anddata-driven parameterization of the meshes. As an application example, we demonstrate a visualization prototype of a 2.5d information landscape that allows for exploration of source code modules of a software system. To this end, each data point is represented by a 3d glyph selected from a glyph atlas according to its type and level-of-detail. We benchmark the approach against a straight-forward baseline implementation using regular *** meshes by evaluating the overall run-time performance. For this, we use a real-worlddataset and synthetic variants with up to 50000 data points. Compared to the baseline implementation, the proposed approach achieves up to a 3000 % higher median FPS count on laptop anddesktop-class hardware and allows for the visualization of up to 1300 % larger datasets interactively. These results suggest that leveraging instanced rendering for 3d glyphs with LOd increases the feasible dataset size for interactive, web-basedvisualization by an order of magnitude.
