Surface features, however, can be difficult to see with traditional styles of rendering particles. Therefore particle systems are being developed that use particles to position strokes rather than draw oriented discs or other more traditional particle shapes. Detection of surface features still remains a problem related to the distribution of the particles. In this research a new technique to sample and position strokes for pen-and-ink style rendering of implicit surfaces is presented. Steering and flocking behaviours are employed to direct particles to sample and render in the same pass.
