Viewer2d sample demonstrates how the functionality of TKV3d package can be used for 2D visualization. It provides samples of 2D objects visualization, dynamic selection and highlighting. It illustratea how to: 1) implement 2D view behavior with V3d_View class, with interactive zooming and panning of the 2D scene; 2) draw 2D primitives like rectangles, lines, curves; 3) draw different types of markers; 4) draw text defined by its font, height, style, angle; 5) display 2D curves of a face' edges and group them using orientation criterion; 6) display zoomable images; 6) display circular and rectangular grids . Viewer2d support zooming ,panning of displayed objects and circular and rectangular grids.
