Abstract: A new 2.5D line drawings cartoon model is presented in the paper.Using the model, given two orthographic views of a line drawing cartoon picture, we can generate a set of new views of the cartoon object in these two pictures and simulate the rotation from one view to another by an specific interpolating techniques proposed in the paper.First, all strokes in the two given pictures are extracted.Then, the correspondences of strokes in these two pictures are computed by shape similarities and paired.Third, from two paired strokes, a depth of a plane that the two strokes lie on is acquired.Fourth, by interpolating points of two corresponding strokes and rotating the resultant stroke in 3D space, the stroke viewed from an arbitrary direction between the two given directions was generated.The visibility of interpolated strokes was determined by the painter's algorithm.Finally, a plausible rendering of the cartoon picture from any views between the two given directions could be generated.Comparing to previous methods, the experimental results show that the model is independent of particular line drawing systems, and the rendering effect is much improved.
