Specially in OpenGL Orthogonal term is used while considering 2D view whereas Perspective is used in 3D.

In Orthogonal view an image or object would act as in 2D environment. And in Perspective view an image or object would act in 3D environment.

Difference between perspective and parallel projection in graphics?

Parallel Projection If the 'Centre of Projection' is at infinity. Perspective Projection If the 'Centre of Projection' is at a point.


The difference between perspective projection and weak perspective projection?

Weak perspective projection is an approximation of the perspective projection. In fact, it is a scaled orthographic projection: first, the object is projected onto the image plane by a set of parallel rays orthogonal to the plane; second, the image of the object is scaled. This approximation works if the object is close to the optical axis of the camera or its dimensions are small relative to the distance from the camera.


What is difference between parallel and perspective projection in Computer Graphics?

Parallel projection does not produces realistic views whereas perspective projection produces realistic viewin parallel projection lines of projection are parallel whereas in perspective projection lines are not parallel and the point where these lines meets is called ceter of projection in case of perspective projection


What is difference between parallel and perspective projection?

perspective projection is defined by straight rays of projection drawn from object to the centre of projection and image is drawn where these rays untersect with the viewplane...while parallel projection is defined by parallel lines drawn from object in fixed direction towards the viewplane In perspective projection centre of projection is at finite distance from viewplane and in parallel projection centre of projection lies at infinite distance. respective projection form realistic picture of object but parallel projection do not form realistic view of object
