Abstract: Creating rotational symmetry field plays a key role for generating the auxiliary mesh structures.However,analyzing and visualizing 3D rotational symmetry fields is challenging due to its complex patterns and the lack of efficient visualization methods.This paper proposes a feature description and visual analysis approach that consists of three stages.First,a regularization sampling is performed.The shape of every local area in symmetrical field is reconstructed to obtain the approximate scalar field of the area.Then,a set of Zernike descriptors are computed at each local sampling point,yielding a series of rotating independent parameters.A multi-variable field is generated after the traversal process for all the local areas.Finally,an iterative visual analysis process is interactively carried out to detect interested features in the field.The results on datasets verify that the proposed method can effectively support the visual analysis of 3D rotational symmetric fields.
