3 point perspective question

[pegasi]

Hi guys,

I have a beginner question about 3 point perspective.
Shouldn't 2 points always meet at the eye level and the third one above or below eye level? like the image below?


I was trying to draw a cube (see photograph below) but I couldn't do it in proportions, it seemed strange. So I took the photo and edited it on photoshop to better see whats happening.


In the photo, only 1 point meets the eye level, when and why does this happen? Is there a book that talks about this? (I haven't finished the Norling's book, but from what I've seen, theres no example of this)

Thanks guys

Multiple Objects in a Scence can have their own vanishing points. Your eye level is actually horizon but vanishing points can be above or below the horizon.

Basically any receding parallel lines have to converge at a single VP but having VPs too close will cause distortion. So keep them well seperated, may be off the page.

Yes, the first picture looks like 3-point perspective, (you don't need the 3rd one on the horizon, in case that was your concern.

Vanishing points don't have to be on the horizon, perhaps you misunderstood that.

Something seems off about that bottom vanishing point on the second picture. I'm no expert, but I wouldn't even bother using a vanishing point for those vertical edges.

Inclined planes have their own vanishing points. It is similar to the experience of a false horizon line when the landscape tilts up or down. Both Loomis Successful Drawing and Norling go over it.

And I don't need to know more than this. Thanks man!
Even thought people say CA is different from before, its still a great place, specially for people who can't have a proper education.
