abstract = {In this paper, we propose an algorithm for enhancing edges of
real-time non-photorealistic renderings. It is based on the edge
map, a 2D texture that encodes visually important edges of 3D
scene objects, and includes silhouette edges, border edges, and
crease edges. The edge map allows us to derive and augment a wide
range of nonphotorealistic rendering styles. Furthermore, the
algorithm is designed to be orthogonal to complementary realtime
rendering techniques. The implementation is based on multipass
rendering: First, we extract geometrical properties of 3D scene
objects generating image-space data similar to G-buffers. Next, we
extract discontinuities in the image-space data using common
graphics hardware to emulate image-processing operations. In
subsequent rendering passes, the algorithm applies texture mapping
to combine the edge map with 3D scene objects.},
