Abstract:
Interpolation of the cross-sectional contours can decrease distance
between adjacent layers. With this interpolation, the data of
cross-sectional contours can be directly used for rapid prototyping,
which makes it easier to integrate RE and RP. On the other side,
similarity and degree of overlapping of contours between adjacent layers
are improved, ensuring the correctness of reconstructed results. A
linear interpolation algorithm is adopted. Research on various methods
for establishing vertex-pairs of linear interpolation based on
cross-sectional contours is performed and an improved linear
interpolation algorithm is proposed. The linear interpolation methods
used for the branched contours based on this algorithm are also
discussed. Application results show that this algorithm is feasible and
reliable.
