A circle in perspective

What is the difference between a circle in perspective and an ellipse and how to draw them.

A circle in perspective is not the same as an ellipse.

An ellipse is a circle viewed from a simple angle – say 45 degrees.

A circle, drawn in a square, of the same diameter as the length of edges of the square makes a tangential intersection with the edges of the square in the middle of each of the walls of the square. Ekk!


An ellipse is what you see if you look at a circle on at a angle. A circle in perspective is a circle viewed using one or two point perspective. One half of an ellipse is the symmetrical with the other half. There are no lines of symmetry in a circle in perspective. One half is smaller and a different shape from the other half.


To draw a circle in perspective. First draw a square in perspective, then cross the square, and find the centre. Mark the tangential intersection points and mark in guess guides for the ellipse. Then squint your eyes, look, judge it and draw.


Vanishing Point and horizon line

The relative positions of the vanishing points and the horizon line affect the orientation of the object in the drawing. The horizon line is sometimes called the eye level line. An object drawn above the eye level line will appear as if it high up, as if it were in the sky, any object below the line will appear lower down, as if it were on the ground.



One, two, three point perspective

How to draw one point, two point and three point perspective. Also a note about curvilinear perspective

The number of points in a perspective, refers to the number of vanishing points.

One point perspective is the sort of perspective used to draw street scenes. Also useful for interiors.


Two point perspective is a simple perspective often used to draw a house.


Three point perspective is used most often to draw medium sized objects such as tables.


Straight line perspective is not really what the eye sees. Perspective is a way of explaining what we see and presenting it on paper in a realistic way.Curvilinear perspective is what you see through a fish eye lens…and also what you see all the time except your brain straightens out the bendy lines automatically. It is the nearest to the truth…but looks weird on paper.If you were in helicopter half way up a skyscraper and looked out the window so that you could see the top of the sky scraper and the bottom at the same time you would notice curvilinear perspective. But the walls of the sky scraper are straight – so this couldn’t be right. It is a visual paradox.

DES513 Assignment 1 – PRESENTATION

Group 1

1. Buy private web hosting*

2. Buy a domain name

3. Create a website which is an example of your interest in an aspect of MM

Group 2

Take your existing web site and create a mobile version**

(You will be assigned to a group in class)

Due date 15 Nov. (50 Marks) (Detail to follow)


Here are some suggestions for hosting companies:

Sometimes you can get a deal where the hosting and the domain purchase is all handled by one company…who then sort out the pointing/forwarding for you also. Costs are as low as $3pm


A good place to start is here:
