What works? Where are the boundaries?ĪI-generated images are potentially limitless. Most companies train machine learning algorithms using real photos that already exist on the Internet. The artificial intelligence is trained in a neural network before it can successfully convert text input into images. ![]() what is the basis for AI-generated images? and German copyright law, for example, AI-generated images are technically not subject to copyright protection because they lack human involvement and creativity. In general, however, it is safe to say that AI-generated images are not automatically copyrighted. This question is difficult to answer because copyright law varies from country to country. Neural networks can be used to create images that mimic the style of a particular artist, or to create images or videos that resemble a particular type of art. AI algorithms can create original, high-quality images by combining and modifying existing images. All the user has to do is make a text entry describing the desired image. Basically, the images are created digitally from scratch. what are AI-generated images and how are they created?ĪI images are images generated using artificial intelligence technology.

Large-Scale Water FX in Houdini is available via a subscription to The Gnomon Workshop, providing access to over 300 tutorials. His credits include Avatar: The Way of Water, Avengers: Endgame and Infinity War, and Star Wars movies Rogue One and The Force Awakens.Ī long-time Houdini user, Miguel started his journey with the software at 14 years old. Miguel Perez Senent is a CG supervisor at Industrial Light & Magic. ![]() ![]() Perez Senent also discusses how to use Houdini’s TOPs to wedge and parallelise simulations and renders.Īs well as the tutorial videos, viewers of the workshop can download the materials needed to create the FX shot, including the animated creature with textures, light, and camera. The workshop also covers how to optimise the scene to run on a single computer: the completed FLIP and whitewater simulations took under an hour to complete. The workshop explores how to achieve realistic motion of whitewater at large scales, including how to modify the behaviour of millions of particles using methods based on real-life observations.įinally, Perez Senent cover the look dev work for the shot within Houdini’s Solaris USD context, rendering it in passes in the Karma renderer, ready to create a final composite in Nuke. Perez Senent then discusses how to generate the simulation mesh, and how to blend it with the rest of the ocean, using the result to define a custom whitewater emission source. He begins by defining a large ocean surface and using the FLIP solver to create the base fluid simulation around the creature, providing tips for making it more realistic-looking, and more efficient. In the workshop, Perez Senent reveals the complete process for creating an epic water simulation shot showing a sea creature breaching the ocean surface, then diving back in. The workshop provides over six hours of video training in Houdini, SideFX’s VFX-industry-standard effects softare, and compositing application Nuke, and can be followed by users with no prior Houdini experience.Ī detailed guide to movie-scale water simulation for VFX and animation work The Gnomon Workshop has released Large-Scale Water FX in Houdini, a detailed guide to fluid simulation for VFX and animation, recorded by Industrial Light & Magic CG supervisor Miguel Perez Senent. ![]()
