The Maths of Perspective in Art
Вставка
- Опубліковано 12 вер 2024
- The Italian architect Filippo Brunelleschi, designer of the dome of Florence cathedral, is also known for developing the rules of linear perspective. In a famous experiment, viewers looked alternately from a vantage point at his perspective painting of the Florence Baptistery, and then the real building, to appreciate the realism made possible by the technique.
This lecture explores the maths of perspective, including modern examples like televised sports where sponsors paint their logos so they look right on camera.

Thank you. Always such astute and fascinating content from Gresham. Outstanding work.
This is my favourite subset of art, the crossover with STEM!
Great lecture. I wish she was using a different microphone. I am having an anxiety attack listening to her being out of breath.
Shouldn’t you write to GC’s tech department if it’s upsetting you so very, very much? It isn’t her microphone or stage, for starters, she isn’t Madonna or something. So you went to all that trouble just to make some personal attack on her (totally normal) manner, and grossly exaggerate an ailment you do not have? Great comment.
Prof Hart was recovering from a really bad cold which accounts partly for some of the breathlessness.
Unless I missed it, a look at the Bayeux Tapestry is deserved ... There were examples of buildings and objects portrayed circa 1067-ish ...
23:20 A brand new optical illusion! I thought at first the drawing was wrong, the right-hand red blob was below the middle one. It isn't! Just scroll so the top of the drawing is cut off. Great talk, makes the art interesting to a mathematician (does it work the other way?) Anyway thanks
A true born speaker!! Great video!!
Maybe would have been nice to show pictures of the conic sections in perspective and how they can look the same under perspective.
So helpful, thank you!
Brunelleschi did not invent the rules for perspective drawing - if you visit Pompey, you will find many beautiful perspective paintings. One might perhaps be correct if we.claim that he rediscovered the rules.
She says he 'discovered' perspective, NOT that he 'invented' it!
In all the myriad drawings ever made before drawing got technical it would be unlikely no one ever closed one eye and drew just what lines they saw. I think the main point is that before there were no rules at all, no ‘science.’ Our lecturer does in fact leave this broadest question as to provenance open, even using the word ‘rediscovered.’
They had rule-of-thumb perspective but not mathematically accurate perspective - the first to fully describe it geometrically was Alberti.
Did you know that a sphere in perspective is not realised by simply drawing a circle? Strange but true! Great lecture, thank you, except for all the bad memories it brings back XD
true
Teach kids to draw geometry it will introduce them to technical drawing
I'm just not that bright.
I wish she slowed down. She is nervous.
You need better graphics.
With all respect you are slowly finding your way to sacred geometry
Great topic, mediocre content, bad vibe speaker :(
Misunderstands art.
This is about technical drawing, not art. I doubt you understand either.
