EWNP has had interesting<\/a> papers<\/a> in recent<\/a> years<\/a>, but when it skipped 2008 I thought it was gone.\u00a0 However it came back in 2009<\/a> with five papers<\/a>, all of which are online except for one:<\/p>\n

Procedural Modeling of Leather Texture with Structural Elements<\/em>:\u00a0 Not currently available online, but judging from a previous paper by these authors<\/a> this appears to be about procedural modeling of the cracks and bumps in leather surfaces.\u00a0 Most real-time applications will use photographed or manually created textures for this, so it is probably not of wide interest to real-time developers.<\/p>\n

Interactive Modeling of Virtual Ecosystems:<\/a> Automatic modeling of plants taking lighting, obstacles, etc. into account.\u00a0 Might be useful as an automatic modeling tool.<\/p>\n

A Geometric Algorithm for Snow Distribution in Virtual Scenes:<\/a> What the title says; might be useful for automated scene modeling, but probably not for runtime use.<\/p>\n

Corotated SPH for Deformable Solids:<\/a> Smoothed Particle Hydrodynamics (SPH) is commonly used in film production for liquids, smoke, etc.\u00a0 This paper discusses how to extend the technique to model deformable solids.\u00a0 Probably not real-time anytime soon.<\/p>\n

Real-Time Open Water Environments with Interacting Objects<\/a>:\u00a0 This combines the Tessendorf FFT-based method for ambient waves with a different method for interactive waves (waves interacting with dynamic objects).\u00a0 This is the most relevant paper for real-time rendering; worth a read.<\/p>\n

Tessendorf’s FFT method is the current gold standard for non-interactive ocean waves, and is widely used in game and film production.\u00a0 A description of it can be found on his publication page<\/a>, under Simulating Ocean Surface<\/em>.\u00a0 Tessendorf’s publication page has many more papers of interest, including an algorithm (called iWave) for interactive waves and reports on particle and volume rendering for film production.<\/p>\n

Insomniac have a particularly efficient and flexible implementation of a variant of Tessendorf’s method, which they extended to support interactive waves as well.\u00a0 This method was used in the game Resistance 2, and Insomniac Games have kindly published not just a white paper on the technique, but actual working code!<\/a> This is part of their admirable Noctural Initiative<\/a> for technology sharing.\u00a0 The Noctural Initiative website is highly recommended, as it includes code which has been used in successful game projects by one of the most highly-regarded studios in the industry.<\/p>\n

Another interesting approach to interactive waves is Wave Particles, which is described here<\/a>.<\/p>\n","protected":false},"excerpt":{"rendered":"
