Drawing Straight Lines

lines, pseudolines, polar coordinates, trilinear coordinates, non-linear programming, geometry We present a graph-drawing algorithm which respects extended co-linearity constraints. These are expressed as a set of ‘straight’ paths in a planar graph. Constraints of this sort are translated into a set of inequalities over polar coordinates of lines. These inequalities provide necessary and suffic...

DALI! - Drawing Animated Lines!

We present an animation system for the creation of non-photorealistic 3D animations. Our system daLi! is able to render images using a common 3D model as input. This model may be enriched with additional information concerning for instance hierarchy, structure and presentation style. The rendering is done analytically, which means the output is resolution independent. It results in a series of ...

Drawing new GM battle lines

The legal battles over GM crop trials in Europe are hotting up, reports Nigel Williams.

Drawing lines by uniform packing

In this paper, we introduce a new approach to line drawing that attempts to maintain a uniform packing density of horizontal segments to diagonal segments throughout the line. While the conventional line drawing algorithms perform linear time computations to find the location of the pixels, our algorithm takes logarithmic time. Also, experimental results show that the quality of line is accepta...
