2D Graphics in C++

These programs solve problems in 2-dimensional graphics and computational geometry.

Label draws a polygon, and a text label which can be moved to various positions around it.  The label positions are calculated so that the convex polygons enclosing the two shapes (the labelled figure and text) are tangent.  The user interface allows a new figure and text string to be selected.  Uses Qt.
