TRANSFORMATIONS

Transformations allow us to uniformly alter the whole picture. The geometric transformations considered here - translation, scaling and rotation are expressed in terms of matrix operation. Homogeneous coordinates are considered to uniformly treat the translations

- Transformations are the building blocks of tricks.

- Positioning, shaping, viewing positions are done by transformations.

- Transformation is additionally used for determining the angle views.

- The transformations that one can perform in 2 dimensions: 2D and 3D

1. Translation: 

Movement of all points of an object within a set direction for an object is understood as translation.

2. Scaling: 

The increasing of coordinates of an object is understood as scaling.

3. Rotation:

Rotation could be a process of fixing the angle of the article. Or Rotation transformation is that the results of the orientation of the initial space being different from the orientation of the destination space. It may be clockwise or anticlockwise. For rotation, we've got to specify the angle of rotation and rotation point in line with transformation point and also Rotation point is additionally called a pivot point. it's about which object is rotated.
