This paper presents a method of parameterization for online freehand drawing objects based on a piecewise cubic Bezier curve approximation. The target is to represent sketches in a compact format within a certain error tolerance with lower computation to be practically adaptable for the online graphics input. A set of user’s intended breakpoints in digital ink is firstly produced in terms of pe...

This article is discussing application of graphic tablet in the art educational University, by introducing it design and work with graphical images related to creation editing raster, vector graphics. Sequential drawing simplest elements for training hand’s muscle memory achieved during classes use pen tablet. The relevance this device opens up new opportunities education when using modern tech...

Nowadays only digital figures are accepted by the most important journals of taxonomy. These may be produced by scanning conventional drawings, made with high precision technical ink-pens, which normally use capillary cartridge and various line widths. Digital drawing techniques that use vector graphics, have already been described in literature to support scientists in drawing figures and plat...

Structured graphics is useful for building applications that use a direct manipulation metaphor. Objectoriented languages offer inheritance, encapsulation, and runtime binding of operations to objects. Unfortunately, standard structured graphics packages do not use an object-oriented model, and object-oriented systems do not provide general-purpose structured graphics, relying instead on low-le...

Sensemaking of large graphs, specifically those with millions of nodes, is a crucial task in many fields. Automatic graph layout algorithms, augmented with real-time human-in-the-loop interaction, can potentially support sensemaking of large graphs. However, designing interactive algorithms to achieve this is challenging. In this paper, we tackle the scalability problem of interactive layout of...

Laser projectors are commonly used in the entertainment industry to create vector-based graphics. In order to present a stable image to observers, the laser projector moves the beam quickly using computer-controlled mirrors. The speed is high enough so that the human eye perceives it as a persistent line of light. In contrast with other vector graphic devices, laser projectors have their own in...

In recent years 2D graphics applications and window systems tend to use more demanding graphics features such as alpha blending, image transformations and antialiasing. These features contribute to the user interfaces by making it possible to add more visual effects as well as new usable functionalities. All together it makes the graphical interface a more hospitable, as well as efficient, envi...

This paper describes the concept of augmented reality, the process of drawing virtual images over the real world using a head mounted display. Using wearable computers, it is possible to take augmented reality software outdoors and visualise data that only exists in a computer. The paper discusses all concepts in detail, and the hardware used to build the system, explaining the various componen...

This paper describes the Junctionality oj a 3D Graphics Raster Processor called TAYRA. TA YRA consists in the most part oj Graphics Raster Pipeline with five major external interfaces: PCI Master/Target, Depth, Texture, Colour and Video Interfaces. The Graphics Raster Pipeline perform'S' all the major OpenGL style (not necessarily compliant) raster functions: scan conversion; lines, spans, tria...
