s = vrml_thick_surf (x, y, z [, options] )
s = vrml_thick_surf (z [, options] )
Returns vrml97 code for a Shape -> IndexedFaceSet node representing a
surface passing through the given points.
The surface may look smoother than that returned by vrml_surf, but it
has twice as many facets.
x : RxC or C : X coordinates of the points on the surface
y : RxC or R : Y " "
z : RxC : Z " "
s : string : The code
If x and y are omitted, they are assumed to be 1:C and 1:R, resp
Points presenting one or more 'inf' or 'nan' coordinates are ignored.
Options :
"col" , col : 3 : Color, default = [0.3,0.4,0.9]
or 3xP : color of vertices (vrml colorPerVertex is TRUE).
"tran", tran : 1x1 : Transparency, default = 0
"creaseAngle", a
: 1 : vrml creaseAngle value. The browser may smoothe the
crease between facets whose angle is less than a.
default = 0
"smooth" : same as "creaseAngle",pi.
