Ahmad is a Graphic Designer in an Animated Movie maker company. Ahmed needs to scale a 3D object and he required a projection of the view plane having a fixed direction. So, which projection technique would you suggest Ahmad perform the scaling and why?

Solution:

I would suggest Ahmad use the perspective projection technique for scaling the 3D object. This is because, In a perspective projection, parallel lines in the 3D object converge towards a single point on the image plane, known as the "vanishing point." This creates the illusion of depth and distance in the image. The closer an object is to the viewer, the larger it will appear, and the farther away it is, the smaller it will appear. This simulates the way the human eye perceives depth and distance, making it a good choice for creating realistic and believable animation. Perspective projection can be adjusted by changing the distance between the viewpoint and the image plane, as well as the position of the vanishing point, to achieve the desired effect.
