What is the difference between orthogonal and perspective projection?

∙ 15y ago
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

∙ 15y agoSpecially 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.

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
In mapping what is the difference between mercator projection and an equal area projection?
the difference between mercator projection and equal projection is 250km apart from each other
What is the difference between orthogonal and orthonormal vectors?
All vectors that are perpendicular (their dot product is zero) are orthogonal vectors.Orthonormal vectors are orthogonal unit vectors. Vectors are only orthonormal if they are both perpendicular have have a length of 1.
What is the Difference between Isometric Projection and Oblique projection?
The difference is that the Isometric projection shows more and accurate drawing than the Oblique project which is just a pictorial method.
What is the difference between map and map projection?
a map projection is a map that has lots of different angles.
What the difference between a map and a map projection?

What is the difference between mercator and Robinson projection?
the mercator projection lines are straight but the robinsons are curved
Can you show me the difference between first and third angle projection?
In a first angle projection, the object stands in between the observer and the plane of projection. In a third angle project, the object and the plane of projection is interchanged.
What is the difference between greatness and madness?
perspective.
What is difference between selection and projection operation?
Projection is from which columns the result should come... Selection means selecting perticular row.
