LucidFusion is a flexible end-to-end feedforward framework designed for generating high-resolution 3D Gaussians from unposed, sparse, and any number of multi-view images. This technology uses Relative Coordinate Maps (RCM) to align geometric features between different views, providing a high degree of adaptability for 3D generation. LucidFusion integrates seamlessly with traditional single-image-to-3D processes, producing detailed 3D Gaussians at 512x512 resolution suitable for a wide range of applications.
