An invitation to discuss computer depiction
NPAR '02: Proceedings of the 2nd international symposium on Non-photorealistic animation and renderingPages 111–124https://doi.org/10.1145/508530.508550This paper draws from art history and perception to place computer depiction in the broader context of picture production. It highlights the often underestimated complexity of the interactions between features in the picture and features of the ...

Hardware-accelerated parallel non-photorealistic volume rendering
NPAR '02: Proceedings of the 2nd international symposium on Non-photorealistic animation and renderingPages 67–ffhttps://doi.org/10.1145/508530.508542Non-photorealistic rendering can be used to illustrate subtle spatial relationships that might not be visible with more realistic rendering techniques. We present a parallel hardware-accelerated rendering technique, making extensive use of multi-...

Computer aided inbetweening
NPAR '02: Proceedings of the 2nd international symposium on Non-photorealistic animation and renderingPages 125–132https://doi.org/10.1145/508530.508552The production of inbetweens is a tedious task for animators and a complicated one for algorithms. In this paper, an algorithm for computer aided inbetweening and its integration in a pen-based graphical user interface are presented.The algorithm is ...

Creating non-photorealistic images the designer's way
NPAR '02: Proceedings of the 2nd international symposium on Non-photorealistic animation and renderingPages 97–ffhttps://doi.org/10.1145/508530.508548We present a novel way for quickly and easily designing non-photorealistic images based on elementary operations which are linked together to create a variety of visual effects. Rather than mimicking a visual effect that an artist has already produced, ...

Abstracted painterly renderings using eye-tracking data
NPAR '02: Proceedings of the 2nd international symposium on Non-photorealistic animation and renderingPages 75–ffhttps://doi.org/10.1145/508530.508544When used by artists, manual interfaces for painterly rendering can yield very satisfying abstract transformations of images. Automatic techniques produce interesting paintings as well, but can only recast pictures in a different style without ...

Hardware accelerated real time charcoal rendering
NPAR '02: Proceedings of the 2nd international symposium on Non-photorealistic animation and renderingPages 59–66https://doi.org/10.1145/508530.508541In this paper, we present simple rendering techniques implemented using traditional graphics hardware to achieve the effects of charcoal drawing. The effects include characteristics of charcoal drawings like broad grainy strokes and smooth tonal ...

HijackGL: reconstructing from streams for stylized rendering
NPAR '02: Proceedings of the 2nd international symposium on Non-photorealistic animation and renderingPages 13–ffhttps://doi.org/10.1145/508530.508533This work shows that intercepting a low-level graphics library command stream and reconstructing a declarative representation is practical and useful, especially for exploring new rendering styles. We show not only how the basic mechanics of ...
