ALPHA: Implementation of a subset of PHIGS

Gullestad, Ylva (1989) ALPHA: Implementation of a subset of PHIGS. [SICS Report]



ALPHA is a support system for applications using interactive computer graphics. The ALPHA system is a subsystem of the PHIGS graphic standard (the PHIGS version presented in dpANS X3.144-198x of October 1986), specifically tailored to the Xerox/Interlisp-D environment. The Programmer's Hierarchical Interactive Graphics System (PHIGS) is a functional specification of the interface between an application program and its graphic support system. PHIGS supports hierarchical graphics, user interaction and 3-D modelling. ALPHA is a detached CommonLisp package in the Interlisp-D environment. The package exports all ALPHA functions to be used and only imports necessary Interlisp-D functions.
