3.3.1 scsvpt/scswnd/scslog/scsorg

1.

Function

Changes the parameters for 3-D normalization transformations.

2.

Call

NumRu::DCL.scsvpt(vxmin,vxmax,vymin,vymax,vzmin,vzmax)
NumRu::DCL.scswnd(uxmin,uxmax,uymin,uymax,uzmin,uzmax)
NumRu::DCL.scslog(lxlog3,lylog3,lzlog3)
NumRu::DCL.scsorg(simfac,vxorg3,vyorg3,vzorg3)

3.

Explanation of Parameters

vxmin3,vxmax3,vymin3,	(R)	The viewport for a rectangular linear coordinate. See Section 1.5.
vymax3,vzmin3,vzmax3
uxmin3,uxmax3,uymin3,	(R)	The window for a rectangular linear coordinate. See Section 1.5.
uymax3,uzmin3,uzmax3
lxlog3,lylog3,lzlog3	(R)	Specifies the log axes for a rectangular linear coordinate. See Section 1.5.
simfac	(R)	The scaling factor for a cylindrical or spherical coordinate. See Section 1.5.
vxorg3,vyorg3,vzorg3	(R)	The position of origin in a cylindrical or spherical coordinate. See Section 1.5.

Notes

(a)

The current parameters can be inquired by

vxmin, vxmax, vymin, vymax, vzmin, vzmax = NumRu::DCL.scqvpt()
uxmin, uxmax, uymin, uymax, uzmin, uzmax = NumRu::DCL.scqwnd()
NumRu::DCL.scslog(lxlog3,lylog3,lzlog3)
simfac, vxorg3, vyorg3, vzorg3 = NumRu::DCL.scqorg().

(b)

UXMIN3!=uxmax3, UYMIN3!=UYMAX3, and UZMIN3!=UZMAX3, and in the case of logarithmic transformations, these parameters must have positive values.

(c)

These parameters become effective when SCSTRF is called.
