Illumination Explorer: All-Frequency Illumination Estimation via HEALPix-Guided Diffusion
Estimating panoramic illumination from a single limited-FOV input image is a critical yet challenging task for rendering realistic objects with complex materials in augmented reality. Existing methods typically either estimate parameterized lighting models or directly generate panoramas in an end-to-end manner. However...
