Figure 1: Existing systems for dimension line layout produce static positions in world space (a). After rotating the view, multiple artifacts are visible, e.g. the dimension lines occlude the model, intersect other dimension lines, or they no longer have a desirable spacing from the model and other dimension lines (b). Our proposed solution enables a user to interactively inspect the model while dimension lines are well positioned in a view-dependent manner, i.e. the dimension lines adapt when the camera moves (c,d). We demonstrate that dimension lines can be used for editing a parametric model, as well as extensions that allow the visualization and control of model parameters other than distances (e,f).
AbstractWe propose a solution for the dimensioning of parametric and procedural models. Dimensioning has long been a staple of technical drawings, and we present the first solution for interactive dimensioning: a dimension line positioning system that adapts to the view direction, given behavioral properties. After proposing a set of design principles for interactive dimensioning, we describe our solution consisting of the following major components. First, we describe how an author can specify the desired interactive behavior of a dimension line. Second, we propose a novel algorithm to place dimension lines at interactive speeds. Third, we introduce multiple extensions, including chained dimension lines, controls for different parameter types (e.g. discrete choices, angles), and the use of dimension lines for interactive editing. Our results show the use of dimension lines in an interactive parametric modeling environment for architectural, botanical, and mechanical models.
In this part of the course, we give a tutorial on how to compose live visuals. First, we talk about hardware and software setup needed for a live visual performance. Then we present concepts to prepare and organize huge media libraries allowing for instant access during performance. Afterwards, we give an overview of the basic content elements and how they can be edited, timed or animated according to musical properties (provided by real-time audio analysis). Finally we explain the workflow during a live visuals performance and show how graphic designs can be successfully embedded in a real-world environments. During the talk, we will make several live demonstrations by using the Soundium system as case in point -but most concepts can be applied to other performance tools as well.The background image shows a typical live visuals setup.
