Workstation transformation is the mapping of normalized device coordinates to physical device coordinates.
V = N.W
Where, V= Viewing transformation
N= Normalization transformation
And W = Workstation Transformation
Steps for Workstation transformation:
1) Translation of object with its window until window is at origin.
2) Scaling of object and window until window has dimensions of viewport.
3) Translation of Viewport to correct position.
Here, window is a finite area in a coordinate system and viewport is an area in device to which window is mapped.
