Viewing 3D Graphics
Nexus GA’s QuickDraw 3D Acceleration supports the following
advanced 3D graphics capabilities:
• QuickDraw 3D RAVE Support
• Perspectively correct texture mapping functions
• Single pass Bilinear/Trilinear filtering
• 16-bit z-buffering (a process that removes hidden surfaces)
• Flat and Gouraud shading
• Floating-point setup engine
• Mip-Mapping
• Alpha blending and fog effects
• Specular Highlights
• Shadows and Spotlights
• Texture lighting
These features make it possible to quickly render 3D graphics,
produce atmospheric effects, calculate light and color shading,
and determine which objects are in the foreground and which
are in the background.
Nexus GA only displays 3D graphics in thousands and millions
of colors. When you use 256 colors, there are too few colors to
display complex 3D textures, so 3D acceleration is not
supported.
You can use the 3D Memory Monitor to see how memory on
your Nexus GA is allocated when displaying 3D graphics. This
allows you to optimize 3D performance. You can also adjust the
compression of textures using the 3D Texture Compression
feature.
