The WinFast 3D L3100 provides workstation class 3D graphics acceleration based on Dual GLINT MX 3D graphics processor & GLINT Gamma lighting and geometry processor from 3Dlabs. The 80MB local buffer and 16MB frame buffer provides professional users a full range of capabilities to handle animation related processes at high resolutions. The WinFast 3D L3100 accelerates 100% of OpenGL 1.1 geometry, lighting and rasterization operations in silicon - including support for 16 light sources, Gouraud shading, per-pixel texture mip-mapping, tri-linear texture filtering, anti-aliasing, multi-plane stenciling and alpha blending with destination alpha support.

System Requirement

Minimum Intel Pentium, Pentium Pro, Pentium II for Windows NT 4.0 Platform with 32 MB RAM

(Windows NT 4.0)

Twin 3D Graphics Processor Design

The two GLINT MX graphics processors can be configured for a single display which is line interleaved. Each GLINT MX renders alternate lines on the display, therefore doubling the rendering speed.

Features

• Dual GLINT MX 3D graphics processor
• On-board GLINT Gamma geometry and lighting processor
• Large size texture buffer to provide smoother 3D operations and faster 3D rendering speed
• Hardware Tri-linear MIP-mapping acceleration
• Hardware Z-buffer for hidden line/surface removal
• Maximum 3D resolution up to 1600x1200 true color
• 128 bit 220MHz RAM DAC on board
• 100% OpenGL compliant
• On board SVGA, not pass through required
• AGP interface, AGP Version 1.0 compliant

Memory Configuration

• 16Mbytes high speed VRAM
• 15/16 and 32 bits per pixel

• 80Mbytes high speed EDO DRAM
• 48 bits per pixel contains Z-buffer, Stencil field, Fast clear control and Graphics ID

3D Features

The WinFast 3D L3100 provides the best acceleration of the rendering features and special effects for a broad range of 3D applications. such as fully OpenGL compliant rendering pipeline, Gouraud shading, phong specular highlights, depth buffering, anti-aliasing, alpha blending, chroma keying, stencilling, fog/depth cueing, and filtered texture mapping.

Geometry and Lighting Pipeline

In addition to it's best-of-breed 3D rendering features, the WinFast 3D L3100 implements the following parts of the Geometry and Lighting Pipeline which provide ultra fast OpenGL acceleration.

• OpenGL Begin/End paradigm for describing primitives
• Texture coordinate generation
• Normal and texture coordinate transformation
• Normalization of the normal after transformation
• Full OpenGL RGB material and lighting for up to 16 light sources
• Two sided lighting
• Polygon offset
• OpenGL Polygon mode and Color Material operations
• Backface culling
• Fog calculations
• Full frustum clipping with an optional 6 user defined clipping planes
• Perspective division and Viewport mapping
• Render, select and feedback modes
• Triangle, Line and Point set up
• Raster Position

Performance

• 3.3 million polygons per second (25 pixel, 50% backface removed)
• 3 million, 10 pixel, 3D vectors per second
• 66 million mip-mapped pixels per second
