This study introduces a sharpness-based 3D model repair method. It effectively fills holes and restores original model shapes using interpolation and sharpness-dependent filtering.

Area of Science:

  • Computer Graphics
  • Geometric Modeling
  • 3D Reconstruction

Background:

  • 3D models often contain holes due to scanning or modeling errors.
  • Existing hole-filling methods may alter the original model's geometry.
  • Restoring sharp features in repaired models is challenging.

Purpose of the Study:

  • To present a novel sharpness-based method for hole-filling in 3D mesh models.
  • To ensure repaired models accurately conform to the original geometry.
  • To recover and preserve sharp features lost during the hole-filling process.

Main Methods:

  • Employs a two-stage process: interpolation-based hole-filling followed by post-processing.
  • Utilizes radial basis function interpolation for implicit surface generation.

  • Applies a sharpness-dependent filtering algorithm for iterative feature recovery.

    • Main Results:

    • The method successfully generates an initial repaired mesh model using surface interpolation and triangulation.
    • Post-processing effectively adjusts the repaired model to match the original shape.
    • Sharp features hidden in the repaired model are recovered through iterative filtering.

    Conclusions:

    • The proposed sharpness-based method is effective for repairing incomplete 3D mesh models.
    • The technique ensures geometric fidelity and preserves critical sharp features.
    • This approach offers a robust solution for 3D model repair.
