This talk aims to transform scientific visualization by developing a user-centered Creative AI-driven 3D authoring system. The goal is to empower scientists to create and manipulate 3D content as easily as using a pen. It addresses challenges in expressing complex phenomena, enabling user-controlled motion and deformation, and facilitating versatile behavior specification. The methodology involves progressive creation, intuitive interaction, narration, and AI integration. The outcome will provide scientists with a dynamic and intuitive tool for expressing complex ideas and fostering creativity in 3D scientific modeling.
