Title: Innovations of Alexis Angelidis
Introduction
Alexis Angelidis is a prominent inventor based in Albany, CA (US). She has made significant contributions to the field of computer graphics, holding a total of 5 patents. Her work focuses on advanced simulation techniques that enhance the realism of visual effects in digital media.
Latest Patents
One of her latest patents is a "Computer graphic system and method of multi-scale simulation of smoke." This innovative method provides a multi-scale approach for simulating incompressible gases in three dimensions, allowing for resolution variation that is suitable for perspective cameras and regions of importance. The dynamics of this simulation are derived from the vorticity equation, and it employs Lagrangian particles that are created, modified, and deleted to effectively handle advection with buoyancy and viscosity. Additionally, boundaries and deformable object collisions are modeled using the source and doublet panel method. The acceleration structure is based on the fast multipole method (FMM), which adapts to account for non-uniform sampling.
Another notable patent involves "Generating a volumetric projection for an object." This process includes providing a surface mesh for an object, generating a voxel grid with volumetric masks for the mesh, and creating a lit mesh that represents a shaded version of the mesh within a scene. The method involves tracing rays to determine interactions between the voxel grid and the lit mesh, ultimately allowing for the creation of a volumetric projection by blurring color sampled from proximate locations.
