Paper Abstract:	Data-glyphs are a common, useful metaphor for visualizing multidimensional data. However, to represent a larger number of glyphs requires an increasing amount of computational power to derive the data-dependent geometry of each glyph. We present a novel visualization implementation for computing and rendering customized data-glyphs for an industry application. Our software utilizes the parallel processing power of the Graphics Processing Unit (GPU) to enable interactive exploration of thousands of multidimensional data-glyphs. This is achieved by passing normalized data values to the OpenGL geometry shader to construct the geometry of each glyph reflecting the data values. The technique is applicable to a variety of glyph designs and supports fast selection between different designs. We demonstrate this technique to render more than 100,000 glyphs at interactive frame rates. To address the challenge of reproducing the technique, we provide a simplified open-source code example implementation that can be used by anyone, including our industry partner.
