- PHIGS is not "on top of Starbase" - PHIGS and Starbase are peer
- interfaces to HP's rendering technology. PowerShade provides lighting
- and shading on low-end devices; both PHIGS and Starbase use
- PowerShade if it is available (PowerShade is a separately priced
- product).

-
- There are several other choices: PEXlib, HOOPS, and possibly other
- APIs from third parties (HOOPS is a third party product). Starbase,
- PHIGS and PEXlib are all HP products and will provide maximum
- performance. I really can't comment on third party products.
-
- For new development, I'd recommend either PHIGS or PEXlib. Both these
- APIs are standard, and you can leverage your investment. PEXlib and
- PHIGS have relative advantages and disadvantages; O'Reilly publishes
- books on both that may serve as a comparison.
