Constructing stream surfaces in steady 3D vector fields

Maintenance of a front of particles, an efficient method of generating a set of sample points over a two-dimensional stream surface, is described. The particles are repeatedly advanced a short distance through the flow field. New polygons are appended to the downstream edge of the surface. The spacing of the particles is adjusted to maintain an adequate sampling across the width of the growing surface. Curve and ribbon methods of vector field visualization are reviewed.<<ETX>>
