We present an example-based approach to synthesizing stipple illustrations for static 2D images that produces scale-dependent results appropriate for an intended spatial output size and resolution. We show how treating stippling as a grayscale process allows us to both produce on-screen output and to achieve stipple merging at medium tonal ranges. At the(More)
We contribute an in-depth analysis of the characteristics of traditional stippling and relate these to common practices in NPAR stippling techniques as well as to the abilities and limitations of existing printing and display technology. In our work we focus specifically on the properties of stipple dots and consider the dimensions and attributes of pens(More)
An important research area in non-photorealistic rendering is the obtention of silhouettes. There are many methods to do this using 3D models and raster structures, but these are limited in their ability to create stylised silhouettes while maintaining complete flexibility. These limitations do not exist in illustration, as each element is plane and the(More)
We present a new method for obtaining non-photorealistic images. These images have two main visual components: silhouettes and non-realistic colouring. Silhouettes are lines that define the form of an object. They are used in classical animation and illustration as the main expressive components. In these applications, if it is necessary, colouring can be(More)
Nowadays, non-photorealistic rendering is an area in computer graphics that tries to simulate what artists do and the tools they use. Stippling illustrations with felt-tipped colour pen is not a commonly used technique by artists due to its complexity. In this paper we present a new method to simulate stippling illustrations with felt-tipped colour pen from(More)
When a patient presents with TMJ pain, it could be all too easy for the orthodontists to turn the other way claiming that their occlusion has no connection with their symptoms and that they are suffering from a biopsychosocial disorder. This abundantly illustrated article attempts to demonstrate that patients can appear to display a stable occlusion even(More)
INTRODUCTION The FACE philosophy is characterized by clearly defined treatment goals: facial esthetics, dental esthetics, periodontal health, functional occlusion, neuromuscular mechanism and joint function. The purpose is to establish ideal occlusion with good facial esthetics and an orthopedic stable joint position. MATERIALS AND METHODS The authors(More)
