Purpose:
|
Defines a constant cross section radius for a variable radius function.
|
|
|
Derivation:
|
var_rad_fixed_width : var_radius : ACIS_OBJECT : -
|
|
|
SAT Identifier:
|
"fixed_width"
|
|
|
Filename:
|
kern/kernel/sg_husk/vrbln/var_rad.hxx

|
|
Description:
|
This radius is an implicit function of the parameter
v. It cannot be evaluated explicitly as
r(v) without partially evaluating the blend surface itself.
