NAME

pv - create a parametric vertex

SYNOPSIS

pv id = x y input_tanget ix iy output_tanget ox oy

where

input_tanget / output_tanget = {TAN_LINEAR | TAN_SMOOTH | TAN_GLOBAL | TAN_FIXED | TAN_FLAT | TAN_STEP | TAN_SLOW | TAN_FAST | TAN_CLAMPED}

DESCRIPTION

Create a new parametric vertex. These vertices are used to define a hermite curve.

EXAMPLE 

# create the vertices
pv pv0_ = 0 0 TAN_SMOOTH 2.5 1 TAN_SMOOTH 2.5 1
pv pv1_ = 60 1 TAN_SMOOTH 2.5 1 TAN_SMOOTH 2.5 1


#create the hermite curve
pcurve motionPath = 
 in PRE_CONSTANT
 out POST_CONSTANT
 cvs pv0_ pv1_
