Non-Photorealistic Rendering (NPR) is an approach in computer graphics that diverges from the traditional goal of creating images that closely mimic reality. Instead, NPR focuses on stylized and artistic rendering techniques, producing visuals that resemble traditional art mediums like painting or illustration. The emphasis is on conveying a specific aesthetic or artistic expression rather than realism.
Imagine a 3D scene rendered in a way that resembles a hand-drawn illustration or a watercolor painting – this departure from photorealism characterizes the essence of NPR. Artists and designers embrace NPR to infuse their digital creations with unique styles, reminiscent of comic books, cartoons, or various art movements.
NPR techniques encompass a wide range of styles, including cel shading, hatching, and stippling, each mimicking traditional artistic methods. These styles can be applied to 3D models, animations, or even entire scenes to evoke a specific mood or to achieve a more stylized and visually striking result.
While photorealistic rendering remains prominent in industries like architecture and product design, NPR has gained traction in entertainment, gaming, and artistic expression. It provides a canvas for creative exploration, enabling artists to break away from strict realism and explore diverse visual languages to tell compelling stories or convey emotions in a more abstract and interpretive manner.
