... **Rotation about an Arbitrary Point:-**
To rotate an object about an arbitrary point, (Xp ,Yp) we have to carry out three steps:
1. Translate point (Xp, Yp) to the origin.
2. Rotate it about the origin and,
3. Finally, translate the center of rotation back where it belongs (See figure 1.).

... **Homogeneous Co-ordinates:-**
As the basic transformations can be expressed in matrix form. But many graphic applications involve sequences of geometric transformations (translational, Rotation and Scaling). Hence we need a general form of matrix to represent such transformations. This can be expr ...

... **Solution:-**
To determine the general form of the scaling matrix with respect to a fixed point P (h, k) we have to perform three steps:
1. Translate point P(h, k) at the origin by performing translation (T1).
2. Scale the point or object by performing scaling (S).
3. Translate the origin ba ...
