A scaling transformation alters size of an object. In the scaling process, we either compress or expand the dimension of the object. Scaling operation can be achieved by multiplying each vertex coordinate (x, y) of the polygon by scaling factor s x and s y to produce the transformed coordinates as (x’, y’). So, x’ = x * s x and y’ = y * s y.

2D Transformation. We can have various types of transformations such as translation, scaling up or down, rotation, shearing, etc. When a transformation takes place on a 2D plane, it is called 2D transformation. Transformations play an important role in computer graphics to reposition the graphics on the screen and change their size or orientation.

The scaling factor s x, s y scales the object in X and Y direction respectively. Formz mac crack. So, the above equation can be represented in matrix form: Or P’ = S. P Scaling process: Note: If the scaling factor S is less than 1, then we reduce the size of the object.

If the scaling factor S is greater than 1, then we increase size of the object. Algorithm: 1.

Make a 2x2 scaling matrix S as: S x 0 0 S y 2. For each point of the polygon. (i) Make a 2x1 matrix P, where P[0][0] equals to x coordinate of the point and P[1][0] equals to y coordinate of the point. (ii) Multiply scaling matrix S with point matrix P to get the new coordinate. Draw the polygon using new coordinates. Below is C implementation.
