NPR Lenses: Local Effect Control for Non-Photorealistic Line Drawings
نویسندگان
چکیده
Modern line rendering systems can create high-quality illustrations. However, the interaction possible with such systems is often limited to selecting an appropriate viewpoint and applying certain line styles to the entire model. NPR Lenses are a new non-photorealistic rendering tool, that allows integrated distortions in 3D with common 2D interaction techniques. NPR Lenses support local adjustments to rendered 3D line-drawings while being view-aligned and still supporting the independent adjustment of the 3D scene.

NPR Lenses: Interactive Tools for Non-Photorealistic Line Drawings
NPR Lenses is an interactive technique for producing expressive non-photorealistic renderings. It provides an intuitive visual interaction tool for illustrators, allowing them to seamlessly apply a large variety of emphasis techniques. Advantages of 3D scene manipulation are combined with the capabilities of viewer-aligned lenses by inserting 2D lens controls into the 3D rendering pipeline. By ...
متن کاملTemporal Coherence for Stylized Animations
Non-photorealistic rendering (NPR) algorithms allow the creation of images in a variety of styles, ranging from line drawing and pen-and-ink to oil painting and watercolor. These algorithms provide greater flexibility, control and automation over traditional drawing and painting. Despite significant progress over the past 15 years, the application of NPR to the generation of stylized animations...
متن کاملA Survey of Image-Morphologic Primitives in Non-Photorealistic Rendering
This paper presents an overview of the image-morphologic primitives used commonly in non-photorealistic rendering (NPR), a subdomain of computer graphics that is inspired by a long tradition of artistic and illustrative depiction. In particular, we survey NPR shading, stroke-based rendering, sparse line drawings, graftals, and area primitives. Such primitives usually cover larger regions on the...
متن کاملNon-Photorealistic Rendering from Stereo
A new paradigm for automatic non-photorealistic rendering is introduced in this paper. Non-photorealistic rendering (NPR) provides an alternative way to render complex scenes by emphasizing high level or salient perceptual features. Particularly, the pen-and-ink rendering style produces sketchy-like drawings that can effectively communicate shape and geometry. This is achieved by combining draw...
متن کاملAc 2007-571: Computer-based Non-photorealistic Rendering
Computer-Based Non-Photorealistic Rendering is a rather elaborate term for a set of 3D rendering techniques that focus on nonrealistic, or stylized, output. Specifically for this paper, the style is a type of concept sketching, done with a computer rather than markers and pens and other traditional tools. This paper will give an overview and show examples of some of the nonphotorealistic render...
