    In our Eurographics 2011 paper, we deal with the challenge of physically displaying reflectance, i.e., the appearance of a surface and its variation with the observer position and the illuminating environment. This is commonly described by the bidirectional reflectance distribution function (BRDF). We provide a catalogue of criteria for the display of BRDFs, and sketch a few orthogonal approaches to solving the problem in an optically passive way. Our specific implementation is based on a liquid surface, on which we excite waves in order to achieve a varying degree of anisotropic roughness. The resulting highlights are shown to follow Gaussian distributions similar to Ward's BRDF model.

  2. LiveClay is nearly getting out of beta soon, we have implemented lots of new things that will do wonders for the topology, including the much awaited Reduce tool and an advanced (and fast ;)) smoothing and relaxation tool that takes fully advantage of subcells : FastSmooth

    Enjoy :)

  4. Hello everyone!
    This is my first online kinda tutorial / hint / walk through video. Excuse me for the voice I'm no radio speaker, and the hour was late ;)

    Basically I tried to walk you through my 3 favorite renderers (since VRay and Mental are pretty covered, I thought those 3 might be fun). 2 of them utilize GPU power one doesn't. Since GPU rendering is becoming more and more visible on the market those two may come to your attention as worth playing with. What I forgot to mention in the video was that iRay was in version 1.2 and Arion in 2.0.2 - it's important since iRay seems to 'slow down' with higher versions... If it comes to Arion it's worth to mention that version 2.4 is just around the corner and some cool new features (to mention one: g-buffer!!!) will be very soon available (at a very fair price).

    If you have any questions about above video please do not hesitate to ask, post, e-mail.
