Artist-Led Suggestions towards an Approach in Content Aware 3D Non-photorealistic Rendering

Referencing practice in traditional drawing, the author attempts to expand upon the knowledge landscape informing current approaches in 3D NPR rendering and thereby to indicate possible areas for fruitful enquiry. The author presents three examples of drawing practice: incomplete perimeters, lines that suggest form and lines that suggest color. Each case is accompanied by examples of drawings from modern or pre-modern artists. A need for a content-aware approach to rendering is indicated. Informing this enquiry is the fact that the author taught drawing for 20 years before working with computer engineers on 3D NPR rendering.
