    TEXTURING COMPOSITE DEFORMABLE IMPLICIT OBJECTS
    (1998-03-01) Zonenschein, Ruben; Gomes, Jonas; Velho, Luiz; DeFigueiredo, Luiz Henrique; Tigges, Mark; Wyvill, Brian
    In this paper we present a method for applying 2D textures onto composite and articulated objects defined by implicit functions. The method generates a particle system associated with the gradient vector field of an implicit function which acquires texture coordinates at a support surface. By extending this method to composite objects, an implicit surface may change its shape in time, while maintaining texture consistency. This approach prevents the appearance of undesirable effects such as ghosting and artifacts at the blending parts of an implicit object.
