They're embedded below: Overall it has been a great SIGGRAPH, I met tons of new people who provided lots of inspiration for new research ideas. Thanks! http://blog.mmacklin.com/2013/04/24/position-based-fluids/ Wed, 24 Apr 2013 06:33:12 +0000 http://blog.mmacklin.com/2013/04/24/position-based-fluids/ Position Based Fluids (PBF) is the title of our paper that has been accepted for presentation at SIGGRAPH 2013. I've set up a project page where you can download the paper and all the related content here: http://blog.mmacklin.com/publications I have continued working on the technique since the submission, mainly improving the rendering, and adding features like spray and foam (based on the excellent paper from the University of Freiburg: Unified Spray, Foam and Bubbles for Particle-Based Fluids). http://blog.mmacklin.com/2010/12/29/blackbody-rendering/ Wed, 29 Dec 2010 08:21:08 +0000 http://blog.mmacklin.com/2010/12/29/blackbody-rendering/ In between bouts of festive over-eating I added support for blackbody emission to my fluid simulator and thought I'd describe what was involved. Briefly, a blackbody is an idealised substance that gives off light when heated. Planck's formula describes the intensity of light per-wavelength with units W·sr-1·m-2·m-1 for a given temperature in Kelvins. Radiance has units W·sr-1·m-2 so we need a way to convert the wavelength dependent power distribution given by Planck's formula to a radiance value in RGB that we can use in our shader / ray-tracer. http://blog.mmacklin.com/2010/11/01/adventures-in-fluid-simulation/ Tue, 02 Nov 2010 01:34:27 +0000 http://blog.mmacklin.com/2010/11/01/adventures-in-fluid-simulation/ I have to admit to being simultaneously fascinated and slightly intimidated by the fluid simulation crowd. I've been watching the videos on Ron Fedkiw's page for years and am still in awe of his results, which sometimes seem little short of magic. Recently I resolved to write my first fluid simulator and purchased a copy of Fluid Simulation for Computer Graphics by Robert Bridson. Like a lot of developers my first exposure to the subject was Jos Stam's stable fluids paper and his more accessible Fluid Dynamics for Games presentation, while the ideas are undeniable great I never came away feeling like I truly understood the concepts or the mathematics behind it.
