Assignment 1 - Perspective Assignment (1 Point and 2 Point Perspective)
Mathematics in Art - FA 1020 \ MATH 1020
Due: Wednesday May 29
Instructor: Derek Brueckner Office: 460 ART Lab
Derek.Brueckner@ad.umanitoba.ca
Objectives:
There is the choice of using
analogue photographs or digital photographs. Either way this
assignment requires two pictures taken with a camera or select two pictures
(photographs from magazines) and depict converging lines, horizon line and
vanishing points on each photograph (or reproductions of each
photograph) This assignment’s ultimate goal for evaluation requires people
to demonstrate a clear and precise comprehension of 1
Point Perspective in one photograph and 2 Point Perspective in the other
photograph with complexity, neatness and accuracy in each photograph.
Details of Assignment Requirements and Format:
Each individual photograph should offer an
interesting, challenging and unique solution for each part of the assignment. Notice
that in all the examples presented below for the on line version of this
assignment’s text there are only photographic examples that depict converging
lines, vanishing points and a horizon line on top of each photographic
image. DO NOT submit drawings or reproductions of drawings or
illustrations!
The presentation of photographs should include:
A) Photo of a 1-point perspective
The 1-point perspective assignment requires an
example of a photograph that demonstrates a 1-point perspective concept in the
purest sense possible. This assignment should not show any 2-point or 3-point
perspective concepts with in this 1-point image. The 1 point perspective
assignment will be evaluated according to: originality of image and level of complexity
in terms of using multiple planes, lines and volumes at various locations,
heights and widths with in a 1 point perspective context.
AND
B) Photo of a 2-point perspective
The 2-point perspective does not need to be as
pure in concept as the 1-point perspective. The 2-point perspective assignment
can incorporate a multiple 2-point and or 3-point concepts into the overall 2-point
assignment. Using multiple 2-point and or 3-point concepts can be a beneficial to
the grade in the over all 2-point perspective assignment provided there is a collective
complexity, originality and accuracy with the overall assignment. As in the 1-point
perspective the 2-point perspective will also be evaluated according to: originality
of image and level of complexity in terms of using multiple planes, lines and
volumes at various locations, heights and widths.
Each photograph will also be evaluated in terms
of depicting: a horizon line, vanishing point(s) and converging lines in the
most complex, correct and neatest way possible.

Details of Assignment Requirements and Format (continued):
The 1 point and 2-point assignments will be submitted
into two separated piles for grading so make sure first and last name are on the
front of both assignments and that the 1point and 2point assignments are NOT
attached together with paper clips, staples, or tape.
Each photograph/assignment should also be on a
separate sheet of paper. Both sheets of paper for each
photographic image should not be any larger than 8.5 x 11 inches. In some cases
people may need to securely add another sheet of paper to depict the
converging lines and vanishing lines but if numerous sheets of paper are
required to depict the converging lines and the vanishing points then there is
a strong possibility that the image may be too difficult to complete
accurately. Any added paper in addition to being securely attached should
also be able to fold in and out easily from the assignment’s 8.5 x 11 inches
dimensions.
Labels
Just to reiterate: on the front of each
photograph people must neatly print their first and last name. Do not put your
student number on either assignment. As well title each work, label one
photograph example as the 1 point perspective and label the other photograph
example as the 2 point perspective. Also stated, each assignment must
label the horizon line and the vanishing point(s)
Analogue Photograph/Option
To complete the analogue version of the
assignment securely attach a sheet of (clear) acetate only at the
top of the picture over each photograph then on the surface of the
acetate draw: neatly and accurately draw converging lines to vanishing points
on the acetate. Also label vanishing points and horizon line in both
perspective examples. This assignment can be drawn by hand, using a straight
edge and a fine tipped marker. If people are worried about mistakes one option
for the analogue version is to start with a non-permanent marker and once the
assignment is correct retrace lines with a permanent marker to prevent the
lines of the non-permanent marker from smudging or disappearing completely. The
other option is to lightly draw converging lines, horizon line, vanishing
point(s) with a pencil on the photograph as an initial guide and then use a
permanent marker to trace the lines and other information on the acetate.
Digital Photograph/Option
There is also the option of doing this assignment
in a digital version by using Photoshop and doing a digital drawing on a
digital photo depicting converging lines, vanishing point(s), a horizon line in
each image, labeling vanishing points and horizon line in both perspective
examples. Once work is completed then print out each of the digitally
manipulated photos on separate sheets of 8.5 x 11 inches. (Obviously if you are
not proficient in Photoshop the digital approach will not be an option)
Consultation with Instructor:
If the perspective assignment presentation and or
the presentation on perspective is unclear even when attending the lectures
immediately make an appointment to see instructor after class or a mutually
agreeable time.

ADDITIONAL INFORMATION FOR ASSIGNMENT:
(information below not reproduced in hard copy of assignment handed out in class)
These images below most samples are evaluated as adequate to good (C to B) examples of work done for the perspective assignment. To be clear as to what is a very good to an excellent (B+ to A) assignment people should make sure they check their notes from class to understand all the expectations for the assignment. Some better examples of the perspective assignment are presented in class but will not be posted. Once again the instructor is willing to assist students outside of class provided the instructor is consulted at a reasonable time before the assignment deadline.
Some Examples of the 1 Point Perspectives Assignment:
The examples collectively presented in the image below on this blog demonstrates an extremely basic understanding of 1 point perspective showing a minimal amount of converging lines in a deep space. Overall the work could be more complex, adventurous and unique in terms of subject matter and overall selection of subject matter in space.
Some Examples of the 2 Point Perspectives Assignment:
The example presented in the image below on this blog demonstrates a clear understanding of 2 point perspective and even though shows many complex converging lines in a deep space should be more adventurous and unique in terms of subject matter and overall selection of space.
In this example of a two point perspective above (and the detail below) all planes parallel in plan view have converging lines going to 2 points (vanishing points) in the image. As in many image examples such as this image a vanishing point or both points may be located outside the frame of the picture plane. As always these two vanishing points in a two point perspective are both positioned on the horizon line.
As suggested in the above description of the examples presented in this assignment these examples may present an understanding of two point perspective in the assignment but are not stellar examples (See the description of examples in the above text of this assignment why these examples are not stellar) as well the last image above is incomplete and kind of quickly done. In the above work for the assignment the person missed the opportunity to draw in many more converging lines to both vanishing points and the horizon line was not drawn in nor was the work labelled with the title, the vanishing points, or the horizon line.
Some Potential Problems in the Perspective Assignment that will Prevent Elevation of Grade during Evaluation Process:
Inaccurate converging lines
Missing converging lines
Missing vanishing points or mistakes or confusion as to where the vanishing points are located
Simple images which lacked complexity: Overall the subject matter in the 1 point perspective image or in the 2 point perspective image did not offer much for converging lines and was overall a very simple presentation of the concept.
An image that is designated as a 1 point perspective image but is actually a 2 point perspective image or a multiple 2 point perspective image.
In some cases an image that is categorized as a 1 point perspective image or more often a 2 point perspective image is actually a 3 point perspective image. This incorrect categorization of the image then creates confusion regarding the accurate locations of the vanishing points on the horizon line and the overall accurate location of the horizon line. Ultimately these confusions cause the depiction of the vanishing points and (in particular) the horizon line to be positioned inaccurately in the image.
In some cases, over all the work(s) does not demonstrate an understanding of what a 1 point perspective image and or a 2 point perspective image is.
Not labeling assignments on the front of the image with name (printed) and not labeling the vanishing point(s) (VP) and the Horizon Line (HL)
Once again please do NOT put your student number on the assignment only indicate your first and last name on the front of each image submitted.
Once again please do NOT put your student number on the assignment only indicate your first and last name on the front of each image submitted.
Perspective Assignment Grade (5% of course) and Percentage Breakdown of Assignment:
GPA Grades on Assignment:
1 Point Perspective Image was a GPA grade out 4.5 (2.5% of course)
2 Point Perspective Image was a GPA grade out 4.5 (2.5% of course)
Note: GPA grade is out of 4.5
The GPA grade for the entire perspective assignment will be calculated by adding the GPA scores of the 1 Point Perspective Image and the 2 Point Perspective Image and then dividing the total of the two GPA grades by 2.
Grading Example to Determine Score on Perspective Assignment:
GPA score of 1 Point Perspective Image: 3.2
GPA score of 2 Point Perspective Image: + 3.0 GPA total for perspective assignment
6.2 / 2 = 3.1 (out of 4.5)
