Graphics Accelerators - Windows 95 & 98

Any Microsoft approved graphics card running with Windows 95b or Windows 98 will allow the Pro/ENGINEER software to provide some enhanced graphics capabilities. However, this is not hardware acceleration, and the shaded rotation/zoom/pan capabilities may not be "real time." Win32 GDI graphics software is used for this, not OpenGL graphics software.

For hardware acceleration, a graphics card must be used that has the capability of quickly rendering 3D objects. At a minimum, for 3D graphics hardware acceleration, a Microsoft approved graphics accelerator with OpenGL capabilities and 8MB memory must be used.

• Testing of OpenGL on Windows 95b/98 workstations is limited and based on availability of Windows 95b/98 graphics accelerators and OpenGL drivers.
• OpenGL is supported for use with Pro/ENGINEER on Windows 95b/98 workstations with Evans & Sutherland AccelSTAR and ELSA GLoria Synergy graphics only.
• If OpenGL graphics capabilities are desired, Windows NT or Windows 2000 is strongly recommended.

Win32 GDI Graphics Capabilities

Windows 95b & Windows 98 workstations with S3 graphics and Win32 GDI
Windows 95b/98 workstations with a Microsoft approved graphics accelerator running with Win32 GDI graphics software will have the following graphics capabilities
ROTATION	Ability to dynamically rotate, pan and zoom shaded images. (Must use config.pro option "save_triangles_flag" . This will enable software rotation - not necessarily real-time.)
LIGHTS	Ability to define and display multiple light sources and surface properties. (Single point or directional type light only, white light only, define position & intensity only.)
ANTI-ALIASING	High quality graphics capability which smoothes jagged lines. (Must use config.pro option "edge_display_quality". This will enable software anti-aliasing)
Use optional graphics config.pro setting "WIN32_GDI".

OpenGL Graphics Capabilities

Windows 95b/98 workstations with OpenGL graphics
Enhanced graphics capabilities, which may be available with Windows 95b/98 and OpenGL graphics accelerators include the following categories
ROTATION	Ability to dynamically rotate, pan and zoom shaded images.
LIGHTS	Ability to define and display multiple light sources and surface properties
TRANSPARENCY	Ability to define and view surfaces transparently.
CLIPPING	Ability to "CUT" through a model.
WIREFRAME DEPTH CUE	Ability to display receding wireframe objects in a "fog".
SHADED DEPTH CUE	Ability to display receding shaded objects in a "fog".
THRESHOLDING	Ability to peel away model surfaces.
ANTI-ALIASING	High quality graphics capability which smoothes jagged lines.
