Broken custom presentations Sample2D_Text and ISession_Text have been replaced by AIS_TextLabel. ISession2D_Curve::Compute() - fixed defining the group without presentation aspects. GeomSources - fixed assigning custom attributes.
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 illustrates 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.
