DCL:GRPH1:SCPACK : 3-D User Interface
The SCPACK is a collection of 3-D interfaces. However, even for 3-D interfaces, parameters such as transformation functions are basically handled by SGPACK, and SCPACK is simply an interface to specify them collectively.
SCPACK contains routines for settings of the 3-D normalization transformation,
settings of the perspective transformation, and for drawing the basic elements
(output primitives) of 3-D graphics.
