Spherical Harmonic

Spherical harmonics (SH) are mathematical functions used to represent data on the surface of a sphere, enabling efficient analysis and manipulation of directional information. Current research focuses on improving the accuracy and efficiency of SH-based models, particularly through novel algorithms like those employing radial basis functions and hierarchical frameworks, and their application in diverse fields such as audio processing (Ambisonics), 3D molecule generation, and geographic data encoding. The widespread use of SHs across various scientific disciplines highlights their significance for representing and processing complex spatial data, leading to advancements in areas ranging from autonomous space navigation to immersive audio technologies.
