GINO v8.0
GINO is the core graphics library in the development suite. It provides over 450 routines and functions for developing professional 2D and 3D graphics applications. The library includes functionality from basic line drawing, fonts, polygons and images to full 3D OpenGL features such as facets, bezier surfaces, lighting, shading and texture-mapping. Metafile input/output includes DXF, JPEG, PNG, ICO, BMP, CGM, Postscript and WMF.
Used in conjunction with the interactive and GUI features of GINOMENU, GINO can produce powerful professional-looking applications.
