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...

This work proposes GeometryAP, a training-free framework for consistent 3D content generation via geometry-informed auxiliary priors in a two-stage "generate-then-reconstruct" pipeline, and proposes the 3D Gaussian-based Global-to-Local Mesh optimizer (GaussGLMeshizer).

SARG-GS is proposed, a geometry-driven 3DGS framework tailored for sparse-view scenarios, comprising a Semantic Augmented Epipolar Fusion (SAEF) module and a Residual Guided Reprojection Compensation (RRC) module, which achieves superior structural completeness and rendering fidelity with as few as three input views.
