Resampling of point-based models

A new method for resampling of point-based models was presented. A novel point primitive called "spherical surface point" was used to approximate the vicinity of a model point. Resampling was accomplished by inserting appropriate points between resampling related points and their neignbor points. Ray tracing was used to render models. Experimental results show that the proposed resampling method effectively solves the undersampling problem of point-based models and achieves satisfied visual quality.
