I've been bothered that many art teachers don't know about higher perspectives such as 4 5 and 6 point perspective. How much did your art teacher teach you? I bet most stopped at 2 or 3 point perspective. There seems to be a lack of knowledge in the art world about higher vanishing points.

I didnt do perspective in high school at all.  Well.. we defined it, and mentioned that things get smaller as they get farther, but that's where it stopped.

In college we made it to 2 pt.

I learned at high school that perspective can have as much points as you want! Depends on direction of objects..

But I only learned that because I tought it should be like this, so I asked my teacher and she showed me some examples. the rest of my (ex)class probably don't know anything more than about 1 and 2 points

Don't think was ever shown anything past two point, but then I didn't do any art beyond grade ten.

From what I've seen of the higher point perspectives they appear to be for fisheye effects which is not so generally useful.

I honestly don't remember. But my art classes are a whopping 2 hours long. And the teachers are... how should I put this? ...not by the book types.

You don't need one. Most of the time the people who are interested in art do just fine by themselves. Art teachers can sometimes be useful for critique and help but when it comes to hardball questions they are no better than the student. I still remember asking my art teacher how to make a perfect cube in 1 point perspective he had no answer. However if this were the Renaissance I could have asked Euclid or Da Vinci and I would have been told the 3D perspective point (x,y,z) transforms into the point (x/z,y/z).
 
Art can be a mixture of concrete concepts and expression but concrete concepts seem to get no attention. Organic free forms are fine but they get far more attention than anything else. Art has a duality of concrete concepts and interpretive concepts. That said art teachers are not my target, compartmentalizing art and other subjects is. There are people who wish to create completely organic and free form art, there are draftsmen who create purely mathematical art and then there are people who like to merge the two. As far as I'm concerned many people never get the chance to explore concrete drawings and if they do they are locked into drafting classes. The Men of the Renaissance have been showing higher concepts in their art and it goes largely ignored and people still ask how to construct perfect shapes in a forced view. Too many people wish to separate art from other areas of study and this can't be done without rejecting underlying principals in science and mathematics. Many people are content to just guess and tinker until something looks right, others wish to know why and how a figure is drawn.
 
 
Other areas of study merge seamlessly with art.
 
Examples
We need Biology pictures or specimens to understand anatomy.
We need Euclidean math to draw accurate forms.
We need History to reconstruct scenes and from the past.
We need English to communicate written symbols and signatures
 
I'm just tired of people teaching art as if it is created in a void. The masters of the Renaissance were students of many areas and made some crossovers in their areas of study. My school system here offers little to the non impressionistic artist. There is no outlet for people who with to draw with accuracy, people who are not content to estimate a picture together. I was just wondering how many art teachers teach organic free form art as well as mixing in some other more concrete principals. What is there for the person who wants an effect and would like to produce it as it would appear naturally? They are just given hazy guesses and knowledge. Art can be abstract and organic but it can also be a calculated expression drawing from all areas of knowledge or any combination of both. Art should be taught as something that can encompass all areas of study or none at all. Don't ask a complicated concrete question unless you are ready for some study. Sometimes I think people compartmentalize their studies into subjects so they can ignore others. If you are poor in a subject the worst thing you can do is just reject or label it as stupid. You would be wise to find a connection to your current expertise and work on that bond until the subject becomes more comfortable.
 
Da Vinci shows that art and math mesh well.
 
 
Do you need to study this? No perhaps not but there is nothing wrong with understanding that some artists like accurate representation. There is still art in this. It is not just cold calculations, even this art is not exact, the lighting could have been taken to the exact level. It could be done using surface vectors and light parameters. His work may be built using concrete formulae but still it is artistic in choice and construction.

I like to build with MDF for the cost, I built a TV cabinet and stool out of the stuff. Only about 15 bucks for an 4 by 8 sheet.

To build the bench you didn't just create art in a void.
 
A short example:
 
Now there is nothing wrong with Cubism. That said what if the artist wanted to create a convincing cup shape? He would be told that the top tilts at an angle but without some understanding they are forced to just guess what angle the circle is rotated at. This is fine for some people, but what if the young artist wishes to get the angle perfect? Well then in today's compartmentalized art class they would be screwed. The art teacher referrers them to the math teacher who goes off on some tangent (lol math humor) and never really explains the proper way to rotate the cup to match the forced perspective. The math teachers rarely deal in problems outside their books (like perspective) so this math/art hybrid question puzzles both teachers.

How does this fit into the discussion? Disorder of what system arising from what falsely theoretical ideas? What are you getting at? How are you tying quantum mechanics into this?

(NB. haven't read much of the thread)

You're right PO, this is a problem. One thing i've found with my art classes throughout school and college is how little the teachers really explain and enforce certain ways of doing things. In the end, all the examiners seem to care about is whether you've researched enough artists, you've written enough notes and gone about the whole thing in the right way, they don't seem to care so much about the final piece. I could be exaggerating a little but that's generally how i see it. If that makes sense.

I hope that wasn't too off topic.

Perspective-wise, i suppose it's up to the artist themselves to learn about this sort of thing in more detail if they're not taught it directly. Which sucks.

No Larwick you are very on topic. I'm glad that somebody really thought about what I was getting at. Basically this thread posed a simple question that I thought would be a good starter to my larger thought about compartmentalizing art. I was very pleased in college when I asked my professors questions they didn't know the answers to. They told that me they would look into it and find out for me and they did. That cup example is a personal example that went through 3 teachers, art,drafting and math. Nobody provided the answer.
 
The rejection of other studies in art is what upsets me. It's not just enough to simply say "I don't know" it turns into "well art is only about expression" the other subjects are more precise and seem to get rejected when coupled with art. Anything complex like 4-6 point perspectives (which relatively aren't) are rejected or ignored. My art teacher became frustrated with me personally because I used rulers and other tools to draw and it was seen as less expressive. This is a single example but the attitude is not just limited to my art. That said, I don't reject organic forms I just see that some people do them and they have some value. I think many teachers (not all of them) don't explore their field they just get their degree and stop.
 
Some wonderful concepts come from mixing areas of study many people are just too overwhelmed to get help. In all fairness these teachers may not know about higher concepts but where is the passion for higher learning? Why does learning need to stop after a Masters Degree? If somebody offers to teach you something embrace the chance there is such a lethargic response to learning because people don't see and can't see the larger implications of the newly acquired techniques. The whole theory of left or right brained people is detrimental to the learning process. It sounds like a childish cliché but people need to try and attempt to learn before they give up or even fail to start.

You are right, but maybe taking it to an extreme with 4 and 5 vanishing points.

I only had one College (High School in USA terminology) teacher that was any good, and he was supportive more than technical. The only technical tip I ever got from any of my teachers was distance haze, and that was only the most basic, did not expand into horizon haze, or mist etc. So I experienced no perspective training at that time.

As an animator, I was glad that John Ewing believed in life drawing (though still clothed, and only young thin women) and acting classes. He did miss on dance. I learned more about drag and flow and arc of motion by watching my GF in her Jaz Dance classes.

I believe that to train the best artists, a confidence course would be great. Most good artists never become great artists because they are too self conscious or scared of making that line.

I now only want to learn from the best. I learn nothing from so called "Art Teachers" as they have never stepped out of their comfort zones. I also learn from teaching people. I seldom get anyone who is masochistic enough to be a student, but I have to put what comes naturally into a thought, consider the thought, and make words to describe thoughts.

I have yet to encounter the perspective math, so I would be interested if there is a book or a link.

Sure I can find some good stuff for you. By the way the distance haze is called atmospheric perspective and is a great way to add depth. It is based on some great scientific principals, atmosphere can be treated as a semi transparent material that blocks out light as it gains in volume.
 
This is a more mathematical approach to plotting single point perspective, be warned that it has some programming related information in it but the concepts transcend programming.
 
To sum it up
Say you wish to plot (x,y,z) in a sheet of paper
 
You simply take the 3D point (x,y,z)
 
the new x value for the projection is newx= X/Z
the new y value for the projection is newy=Y/Z
 
This simple formula lets you play with a 2D single vanishing points. Some bad results can occur if you use a negative Z value there is a fix but I don't know the proper technique at the moment.
 
 
 
 
 
Some of it still blows my mind. Break out those handy cosine and sine functions kiddies! The following tutorial is best for people with some programming ability.
 
 
This looks promising as well. Again the more complex the perspective, the less information is available it appears...

It is all well and good if you have a programming background, and I do not. In fact Sine Cosine and Tangent are the only thing I missed. My teacher way back in the day (a staffing shortage) just admitted that he did not understand that part of math, and skipped the subject. I always knew that it was going to be the only part of math that I would need in the real world.

I blew up some heads with this old tutorial.
 
 
Basically cosine and sine are used to find distances given an angle along the x and y Axis respectively. They allow you to define points along a circle quite easily. I will do another tutorial if necessary.
 
And if you are interested this is a really old tutorial on finding the color inbetween two other colors.
 
 
I am going to probably make a .pdf with a better learning curve. For people interested in getting a little math in their art. It is my responsability to spread what I have learned so others can surpass me.

I thought I was the only one who was deprived of perspective in school. We only learned ONE point perspective, and that was in 9th grade. -.-
I knew there was no way that this was the only point of perspective, so I went online and found that there were at least three points, but I never knew you could have even more than that, though I had thought of the possibility of trying it out. Thanks for bringing up this issue.

Semi random juxtaposition of words and phrases is best left to the professionals.
 
I should get started on that .pdf file I've been meaning to write on incorporating formulae into art. Perhaps a program would be easier.

Well, in grade 6-8 we didnt do much drawing (etc.), but a few times we did perspective, and I think we got up to 4 point in grade 6, and re-learned it in 7-8. I totally forget it now. Anyways, now Im in grade 9 and taking art, and we have done ZERO creation of art to this point. We've done more writing in art class than in Business. Which I know it's neccisary, but really =_=

I never learned in scool. I just determine my Perspectives by the way they look and if it looks right or not. But I know the basics, but nothing too sophisticated.
