nf3d

Rectangular facets to plot3d parameters

Calling Sequence

[xx,yy,zz]=nf3d(x,y,z)

Arguments

:x,y,x,xx,yy,zz 6 real matrices :

Description

Utility function. Used for transforming rectangular facets coded in three matrices x,y,z to scilab code for facets accepted by plot3d.

Examples

//A sphere...
u = `linspace`_(-%pi/2,%pi/2,40);
v = `linspace`_(0,2*%pi,20);
x= `cos`_(u)'*`cos`_(v);
y= `cos`_(u)'*`sin`_(v);
z= `sin`_(u)'*`ones`_(v);
//plot3d2(x,y,z) is equivalent to...
[xx,yy,zz]=nf3d(x,y,z); `plot3d`_(xx,yy,zz)
