Line Integral Convolution for 3D Surfaces
Line Integral Convolution (LIC) is a very powerful vector field visualization technique as it can effectively reveal the global and complex structures of a flow field. All the existing LIC algorithms, however, requires the one-to-one correspondence between input image pixels and grid cells, and hence restrict their use only for 2D/3D structured grids. In this paper, we present a new algorithm, for convolving solid white noise on triangle meshes in 3D space, and extend. LIC for visualizing the vector field on any arbitrary 3D surfaces, such as a contour surface output from the Marching Cube algorithm, or a surface of a 3D object represented implicitly by a part of a curvilinear or an unstructured grid.
