Description:
|
A
gvector is a composition of three real numbers representing the
x,
y, and
z components of a 3D vector. This is an
ACIS-defined Scheme data type used to represent a (mathematical) vector with magnitude and direction. It is named
gvector only to differentiate it from the inherent Scheme data type
vector, which represents an array.

where the first double number is the
gvector's
x component,
|
|
the second double number is the
gvector's
y component,
|
|
and the third double number is the
gvector's
z component.
