Simulating the surface of litchi grain leather by creating quadrilateral-continuous pattern in Adobe Illustrator CC

The paper illustrates an approach of creating quadrilateral-continuous pattern for simulating litchi grain leather surface in order to solve the issue that the designer of leather products cannot simulate litchi grain surface simply or realistically. Adobe Illustrator CC is a kind of design software that possesses pattern-editing mode. Based on both the image of the litchi grain leather sample scanned by stereo microscope and the rationale behind the quadrilateral-continuous pattern, we obtained the wrinkles and pores of litchi grain leather sample in Adobe Illustrator CC without using any sophisticated algorithm, which in turn resulted in realistic and various effects on the surface of litchi grain leather. Moreover, the pattern exported from Adobe Illustrator CC can also be widely used in other kinds of design software.
