Des pite great progress in both explicit reconstruction and implicit reconstru ction, it remains a challenging task to reconstruct a polygonal surface eq uipped with feature lines, especially when the input point cloud is noisy and lacks faithful normal vectors. In this paper, we develop a multistage algorithm, named RFEPS, to address this challenge. The key steps include ( 1)denoising the point cloud based on the assumption of local planarity, (2 )identifying the feature-line zone by optimization of discrete optimal tra nsport, (3)augmenting the point set so that sufficiently many additional p oints are generated on potential geometry edges, and (4)generating a polyg onal surface that interpolates the augmented point set based on restricted power diagram. We demonstrate through extensive experiments that RFEPS, b enefiting from the edge-point augmentation and the feature preserving expl icit reconstruction, outperforms state of the art methods in terms of the reconstruction quality, especially in terms of the ability to reconstruct missing feature lines.\n\nRegistration Category: FULL ACCESS, EXPERIENCE P LUS ACCESS, EXPERIENCE ACCESS, TRADE EXHIBITOR\n\nLanguage: ENGLISH\n\nFor mat: IN-PERSON URL:https://sa2022.siggraph.org/en/full-program/?id=papers_180&sess=sess15 3 END:VEVENT END:VCALENDAR
