Getting Started
This chapter introduces Intergraph Computer Systems’ RealiZm II graphics accelerators. It
also provides information on connecting the monitors and getting started using a workstation
equipped with a RealiZm II card.
RealiZm II Cards
RealiZm II cards are high-performance, OpenGL-based, 3D graphics accelerators that include
rasterization, optional texturing, and optional geometry acceleration:
u
ZX13, VX113, and VX113 AGP include 16 MB of frame buffer memory and support
resolutions up to 1.3 Mpixels (1280 x 1024).
u
ZX25 and VX25 include 32 MB of frame buffer memory and support resolutions up to
2.5 Mpixels (1824 x 1368).
RealiZm II Features and Functions
RealiZm II graphics accelerators offer many advanced features and functions, including the
following:
u
Hardware support of Windows NT graphics (both GDI and OpenGL graphics operations)
u
Gouraud shading support and antialiased vector support
u
16 MB (ZX13, VX113, VX113 AGP) or 32 MB (ZX25 and VX25) of frame buffer
memory
u
Industry-standard Peripheral Component Interconnect (PCI) bus interface with high-speed
direct memory access (DMA) engine (ZX13, VX113, ZX25, and VX25)
u
Industry-standard Accelerated Graphics Port (AGP) interface with high-speed DMA
engine (VX113 AGP)
u
128 video planes
u
Support of industry standard multi-sync monitors
u
Optional hardware texture processing support with 4 MB, 16 MB, 32 MB, or 64 MB of
texture memory (ZX13, ZX25, VX25); standard 16 MB texture memory for hardware
texture processing support (VX113 and VX113 AGP)
u
Optional geometry acceleration for lighting and transformation operations
