1	Remediating abstracted character designs into a three-dimensional medium Karlsson Pellnor, Märta-Louise January 2020 (has links) This paper examined how well different levels of visual abstraction in 2D characters can be remediated into 3D, focusing on the viewer’s opinion of the character and perception of its role or personality. Artifacts of two characters—six artifacts in total—were used in order to examine this. Each character’s artifacts consisted of 1) a visually abstracted 2D design, 2) an abstraction-preserving 3D model, and 3) a non-abstraction-preserving 3D model. Six participants were interviewed, and were asked to state their opinion of each artifact as well as their interpretation of its role and personality. The results showed that a 2D to 3D remediation method aimed at preserving design choices either did not affect the viewer’sopinion of the character, or made them like the 3D character more than the 2D version. Furthermore, the perception of character personality had slight differences in the abstraction-preserving 3D model compared to the 2D image.

2	Illustrative Visualization of Anatomical Structures Jonsson, Erik January 2011 (has links) Illustrative visualization is a term for visualization techniques inspired by traditional technical and medical illustration. These techniques are based on knowledge of the human perception and provide effective visual abstraction to make the visualizations more understandable. Within volume rendering these expressive visualizations can be achieved using non-photorealistic rendering that combines different levels of abstraction to convey the most important information to the viewer. In this thesis I will look at illustrative techniques and show how these can be used to visualize anatomical structures in a medical volume data. The result of the thesis is a prototype of an anatomy education application, that makes use of illustrative techniques to have a focus+context visualization with feature enhancement, tone shading and labels describing the anatomical structures. This results in an expressive visualization and interactive exploration of the human anatomy.

3	Visualisation, navigation and mathematical perception: a visual notation for rational numbers mod1 Tolmie, Julie, julie.tolmie@techbc.ca January 2000 (has links) There are three main results in this dissertation. The first result is the construction of an abstract visual space for rational numbers mod1, based on the visual primitives, colour, and rational radial direction. Mathematics is performed in this visual notation by defining increasingly refined visual objects from these primitives. In particular, the existence of the Farey tree enumeration of rational numbers mod1 is identified in the texture of a two-dimensional animation. ¶ The second result is a new enumeration of the rational numbers mod1, obtained, and expressed, in abstract visual space, as the visual object coset waves of coset fans on the torus. Its geometry is shown to encode a countably infinite tree structure, whose branches are cosets, nZ+m, where n, m (and k) are integers. These cosets are in geometrical 1-1 correspondence with sequences kn+m, (of denominators) of rational numbers, and with visual subobjects of the torus called coset fans. ¶ The third result is an enumeration in time of the visual hierarchy of the discrete buds of the Mandelbrot boundary by coset waves of coset fans. It is constructed by embedding the circular Farey tree geometrically into the empty internal region of the Mandelbrot set. In particular, coset fans attached to points of the (internal) binary tree index countably infinite sequences of buds on the (external) Mandelbrot boundary. mathematical visualisation visual mathematics visual notation visual object visual abstraction visual abstraction in time visual representation visual argument visual and time-based digitalthesis thesis by animation pattern perception mathematical perception abstract choreography visualisation of rational numbers Farey tree Farey sequence Mandelbrot buds torus rational flowson the torus rational lattice on the torus cyclic groups and regular polygons.
