- 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.
