CubeAtlas generates 360-degree panoramas from a perspective image and text by arranging cubemap views in one canvas, making spherical neighbors local to a pretrained diffusion transformer. Sparse attention leaves target-token count unchanged while reducing denoising time to 0.84× the ERP baseline. On RealSee3D, SeamCube error is 0.0064 versus CubeDiff’s 0.0229; this measure does not establish recovery of unseen surroundings.
