Orthographic Projection
When the direction of the projection is normal (perpendicular) to the view plane, we have an orthographic projection. In another word, Orthographic projection means a method of representing the exact shape of a 3 Dimensional object on a 2 Dimensional sheet in two or more views.
It is also simpler than the two parallel projections. In orthographic projections, the direction of the projection is perpendicular to the projection plane. In that projection, Projectors are parallel to each other and also perpendicular to each other. It is also called a Multi-view Projection.
Advantages
- One of the advantages of this projection is it can preserve both distances and angles.
Disadvantages
- There are so many hidden surfaces that in the real images can not clearly visible.
Difference Between Orthographic and Isometric Projection
Pre-requisites: Projections in Computer Graphics
Representing an n-dimensional object into an n-1 dimension is known as projection. It is the process of converting a 3D object into a 2D object, we represent a 3D object on a 2D plane {(x,y,z)->(x,y)}.
