illumination model,
1) FLAT SHADING
2) INTENSITY INTERPOLATION SCHEME ---> GOURAUD SHADING 

IT CONSISTS OF THREE STEPS
1) average normal unit vector
2)

working on discrete signals
==================================
operations on discreate signals

1) Fllipping F[n] =F[-n]
2) Scaling F[n]=F[2*n]  // samples are lost in  
3) shifting a signal X[n-n0]= X[n-1] //start the signal with one usnit late or early
Shift , Flip and Scale
====================
4) X[-2n+3]

1) symmetry : f(r,thetha)==f(r,-thetha) then a curve is symmetrical about thetha i.e.  theta = PI/2 or PI or ZERO.
curve is symmetrical about f(r,thetha)==f(-r,thetha) then curve is symmetrical about pole. 
2) tangent to pole : a curve passing though pole is called tangent to pole.
r=a(1+cos(theta)).
putting r=0 whether the theta exixts if not then curve does not exists at r=0 else exists.
3) curve tracing : means for calcutes values of theta you have to trace the curve .
thetha= ZERO,PI/6,PI/4,PI/2,PI.
4) Asymptote: for which values of theta r becomes infinite.
5) tangent to the curve:  tan(phai) = r / derivative(r,theta);
		calculates the values of PHAI to evalutes .
