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
What else can I help you with?
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 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 mercator and Robinson projection?
the mercator projection lines are straight but the robinsons are curved
What is the difference between a map and a 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 map and map projection?
a map projection is a map that has lots of different angles.
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.
What is the difference between ihrm and hrm?
The difference between IHRM and HRM is that IHRM deals with much broader perspective while HRM deals with narrow perspective.
Difference between isometric view and isometric projection?
I think both are same. There is difference between isometric view and isometric drawing that is of size.
