“…The Fourier transform was also used in the morphing technique of the volumetric model [12], the modeling through the generalized cylinder [13], and biomedical modeling [14,15]. With the Fourier transform, Bertram et al [16] proposed a wavelet representation of contours for the compression and the hierarchy of multi-resolution representation.…”

The 3D progressive compression has received great interest in recent years, mainly due to the need for transmitting a large model over the network. This paper proposes a new compression method using Fourier descriptors for the contour shapes. Upon acquisition of the set of planar contours, a vertex list is obtained. The vertex coordinate (x, y) on the plane, is considered as a complex value (x + jy), which is transformed to the frequencies by using the Fourier descriptor. The priority filter based on the magnitude of frequencies determines the significance of the frequency components. Instead of using all frequencies, the most significant frequencies are selectively used to reconstruct the contour by the inverse Fourier transform. As a result, data size in the frequency domain is considerably reduced. Three application examples are demonstrated to show the effectiveness of the proposed method.

Haptic interfaces offer an intuitive way to interact with and manipulate 3D datasets, and may simplify the interpretation of visual information. This work proposes an algorithm to provide haptic feedback directly from volumetric datasets, as an aid to regular visualization. The haptic rendering algorithm lets users perceive isosurfaces in volumetric datasets, and it relies on several design features that ensure a robust and efficient rendering. A marching tetrahedra approach enables the dynamic extraction of a piecewise linear continuous isosurface. Robustness is achieved using a continuous collision detection step coupled with state-of-the-art proxy-based rendering methods over the extracted isosurface. The introduced marching tetrahedra approach guarantees that the extracted isosurface will match the topology of an equivalent isosurface computed using trilinear interpolation. The proposed haptic rendering algorithm improves the consistency between haptic and visual cues computing a second proxy on the isosurface displayed on screen. Our experiments demonstrate the improvements on the isosurface extraction stage as well as the robustness and the efficiency of the complete algorithm.
