How can you represent a sphere with parametric equations?
Author
? or, generally and 3-d sphere. Not generating the points, representing them as an equation. ( or set of )
P=(x0,y0,z0) is the sphere ''s centre , R is the radius
(x-x0)^2+(y-y0)^2+(z-z0)^=r^2
in parametric form we have the spherical coordinates
x=R*sen(a)*cos(b)
y=R*sen(a)*sen(b)
z=R*cos(a)
0<=a<=Pi , 0<=b<=2*Pi
from spherical to carthesian
R=sqrt(x^2+y^2+z?2 ) , a=atan(y/x) , b=atan(sqrt(x^2+y^2))/z
(x-x0)^2+(y-y0)^2+(z-z0)^=r^2

x=R*sen(a)*cos(b)
y=R*sen(a)*sen(b)
