VISUALIB (c) Graphics Library
( Borland C++ / Turbo C++ version )
Visualib is a comprehensive state-of-the-art graphics library for Microsoft
Windows environment. It contains powerful and efficient functions to transform
and display both 2D and 3D graphic objects. Visualib can be used with either
Microsoft C / Microsoft Windows Software Development Kit version 3.0
or Borland C++ / Turbo C++ for Windows version 2.0 and up. This a free trial
version for Borland C++ / Turbo C++ for Windows.
Main features of Visualib includes:
<< 2D and 3D Graphics Viewing Systems >>
User can establish virtually unlimited number of independent 2D and 3D
viewers. In each viewer, user can select various parameters such as the
viewport, eye position, perspective or orthogonal projections, view volume,
etc.
<< Transformation functions and stack >>
Visualib provides a sophisticated transformation mechanism to support
virtually all types of graphics transformations. Visualib maintain a
transformation stack which can be used in conjunction with the transformation
functions to achieve flexible and efficient graphic effects.
<< Graphic object drawing functions >>
Visualib supports a full set of common 2D and 3D drawing functions such as
lines, polygons, ellipses, spheres, polyhedra, etc. Backface culling is
implemented for 3D viewers. User may also select double buffer mode to
achieve smooth animation effects.
Visualib also provides the powerful curve and surface drawing functions such
as Bezier, Hermit curves, B-Spline, NURBS curves and surfaces.
Visualib greatly extends the capabilities of windows' GDI functions. Visualib
uses float type for specifying coordinates and implements its own clipping in
homogeneous coordinates, which effectively avoids the common integer
overflow problem associated with the GDI functions. However, all GDI functions
are still available and the function calls from both systems can be used at
the same time. Visualib can be used with any types of device context -
screens, printers, or memory. Consequently, the same routine for display can
also be used for printing or storing. Visualib uses the attributes such as
colors, line width of the device context set by the GDI functions.
Visualib is the only graphics package for the Windows that delivers the
power of high-end graphics work stations. For everyone interested in using
graphics in the Windows, Visualib is an indispensable tool.
Whether you are developing a CAD application or simply drawing
a nice business char, you will find that Visualib can save your time and
money. Visualib will free the user from writing highly sophisticated and
tedious graphics routines and obtain beautiful 2D and 3D graphics with ease.

format. You may read it by running WinHelp or access it from the demo program
VLIBDEMO.
You may try Visualib free of charge for 45 days. After the free trial period,
you must register it with Visual Tech if you decide to continue using
Visualib. See REGISTER.TXT for more information.
