Real-time photorealistic gemstone rendering has recently become a demanded field. Diamond CAD modeling is widely used for creating new diamond cuts. The cut designer should be able to observe diamond’s light reflection properties, such as brilliance (white reflected light through the top of a diamond) and fire (colored light reflected from within a diamond) while editing the shape of the gemstone. Besides, specialized software is needed for the advertisement video generation, since offline rendering of gemstones in 3DSMax of Maya takes huge amount of time.
This talk will be dedicated to several real-time techniques, used in the gemstone rendering. An image-based technique for glare rendering, a caustics rendering method, adapted for gemstones, and several finite lens aperture simulation techniques will be presented.
