Hi,
I have found following eq of parametric form:
x=x1+rcosθ, y=y1+rsinθ
At:
http://doubleroot.in/straight-line-parametric-form-theory/#.UqyLmPSnopA
However, another parametric form for line:
P=P1+t•(P2-P1)
x(t)=x1+(x2-x1)•t
y(t)=y1+(y2-y1)•t
is given at:
http://www.it.hiof.no/~borres/j3d/math/param/p-param.html
I have found that parametric form is not unique. Is it possible to convert second form into first form? Somebody plz guide me.
Zulfi.
