LIANG Wei-wen, BIN Hong-zan. Research on the perspective texture mapping of free-form surface[J]. Editorial Office of Optics and Precision Engineering, 2002,(4): 354-358DOI:
a perspective texture mapping is proposed in this paper. First
the principle of perspective transformation and its application in the texture mapping of free-form surface are presented. During the perspective texture mapping
the precision of approximation of bicubic patches is better than that of polyhedrons
so bicubic Bezier patches are used to approximate free-form surface. Then
the arithmetic of the perspective texture mapping is introduced: through getting the corresponding relationship between the texture space and the object space
and the corresponding relationship between the object space and the screen space
we get the corresponding relationship between the texture space and the screen space. Finally the aliasing is discussed. This method can also be effectively used for polyhedron and free-form body.
