SUMMARY

The discussion centers on understanding the concept of angular convergence between two points, specifically between a camera and a building. The key formula provided is arctan(h/x), where 'h' represents the height of the building and 'x' is the distance from the camera to the building. The conversation also touches on how perspective changes with distance, particularly when considering the horizon. A link to the Wikipedia page on the horizon is shared as a resource for further understanding.

PREREQUISITES
  • Basic understanding of trigonometry, specifically the tangent function.
  • Familiarity with the concept of perspective in photography or visual representation.
  • Knowledge of angular measurements and their applications.
  • Understanding of the horizon and its significance in visual perception.
NEXT STEPS
  • Research the application of arctan in real-world scenarios, such as photography and architecture.
  • Explore the mathematical principles behind perspective drawing and visual representation.
  • Learn about the physics of light and how it affects perception of distance and size.
  • Investigate the concept of the horizon in different contexts, such as geography and astronomy.
USEFUL FOR

This discussion is beneficial for photographers, architects, visual artists, and anyone interested in the mathematical principles of perspective and visual perception.

Hi!
I want to know, the value of perspective in exact number.
Like how much is the angular convergence between two points


A. Camera ----------------------------------------------------------- Building B.


In the above how much would building converge, and what would be the size, when viewed at point A.

Thanks
V.

Your question is much too vague. Your object has to have some size in order to subtend an angle. If building B has height h, and the distance from camera A is x, then the angle between the base of B and top of B, as seen from camera A, is arctan(h/x). Is that what you are asking?
 
Thanks,
So, you mean it would change as per the distance between eye(camera) and the view(building) ?

But what is the answer, if i replace the building with horizon ? How would i know the distance of horizon from my eye ?

Nevermind.. got it here :
http://en.wikipedia.org/wiki/Horizon

Thanks.
