Image Description, by The image shows a new Non-Photorealistic Rendering technique, displayed in real-time using the GPU. Strokes are oriented along an estimate of the curvature tensor of the surface. The right half of the image shows tensor line-integral convolution (Hyper LIC) applied to the tensor of curvature. The image is generated in our Open-Source "Graphite" software.
