Simplify the following text for a Grade 8 native English-speaking person.
Original: Orthographic projection ( or orthogonal projection ) is a means of representing a three-dimensional object in two dimensions . It is a form of parallel projection , where all the projection lines are orthogonal to the projection plane , resulting in every plane of the scene appearing in affine transformation on the viewing surface .
Simplified: It is a form of parallel projection , where the view direction is orthogonal to the projection plane .
