A new and faster way to browse physics-based animations

Computer-based animators tasked with bringing fictional worlds and characters to life are helped by simulators that can model the many possible ways an object or liquid can move through a physical space. These emulators are known as “solution tools,” and they provide a solid start to your animation work. but there is a problem. As computers become faster, these solutions are often created too much Options for Painter to sort effectively by finding just the right option.

This video summary explains how to navigate the many unified worlds and shows examples of how to simulate scenarios involving a variety of physical phenomena.

“Simulations can return thousands of options,” said Purvi Joel, a doctoral student in computer science at Stanford University, who along with her mentor, Professor Doug James, devised a new approach: to refine the research and narrow the results to the most promising options.

They call it Surfing Unified Multiple Worlds, and they will be releasing their approach for the first time at the upcoming SIGGRAPH 2022 conference in Vancouver, BC, the premier annual gathering of computer graphics and interactive technologies. This approach can speed up the search for animators, by limiting the options that emulators have to navigate, and reduce computation time and expense. Ultimately, the researchers hope, this software will allow artists and scientists to interact with transducers with unparalleled ease and efficiency.

“We have this very interesting struggle in this field, as computers are getting faster and more parallel every year, and they can do more, but humans are the ones who have reached the limit,” said James, a professor of computer science.

parameters and time

Solvents are controlled by the input parameters – the physical dimensions of the object in the animation. In one example, researchers used uniform browsing of the multiple worlds to trigger an imaginary bowling alley. Parameters include starting speed and ball position.

The parser simply steps through the parameters incrementally, one by one, and simulates several possible outcomes over time. The main point is that there can be many input parameters, the longer and more complex the animation, the more parameters and computation time are required to generate simulations, and more options are created.

“If you are an animator and you have an idea, you have to set these parameters manually, and then sort all the results one by one,” Joel explained.

Browsing the multiple unified worlds allows illustrators to create “queries” to narrow down options to make it easier to select very specific outcome options. Queries can, for example, limit results to only those the animator is interested in – including those that are either “in” the desired range of possibilities or, conversely, excluding those that are “not in” that range. . Animated models are available for viewing on the researchers’ website.

When asked to move a stuffed armadillo falling down a spiral staircase, for example, an animator might generate a query in the unified browser saying, “Just show me the options where an armadillo falls all the way down a staircase.” Surrounded by a bowl, the painter can limit the options only to those where all the cubes remain in the bowl, or perhaps where not one, but only one, falls. A small blue ball to be launched in a fantasy sandcastle might specify “give me samples where the left front turret was smashed” or “only the top turret”.
