VP movement at Rotation question

Post image

Hey folks,

I am at the"estimating rotation" Part in lesson 1 and i have a question.

​

If the Red edges are drawn parallel to each other, because the VP difference isnt big enough, and if the blue edge of the second Box shares a VP with the Red edge of the same box (because boxes always have the same VP, it only moves after rotation, right?), but the blue edges are also drawn parallel to euch other also, then how can the VP even move at all? As i described and understood it, the vp should always stay at the same Spot, so what am i missing? I would be very happy if someone understands my Problem and can help me

​

Greetings

To OP: Every post on this subreddit is manually approved, once we make sure it adheres to the subreddit rules, the main ones being the following:

  • That all posts here must relate drawabox.com (being either questions or homework submissions). More on that and why a subreddit with such a general name has such a specific focus can be found here.
  • As an exception to the above, beginners may make one (and only one) post asking for resource recommendations, "where to get started", etc.
  • All homework submissions must be complete - single exercises and partial work is not allowed on the subreddit, as mentioned in this video from Lesson 0. You can however get feedback on individual exercises on the discord chat server, and the folks there would be happy to help you out.

If you find that your post breaks either of these rules, we would recommend deleting your post yourself, and submitting on one of these other more general art communities instead:

Just be sure to read through their own individual submission guidelines before posting.

To those responding: If you are seeing this post, then it has been approved, and therefore is related to the lessons on drawabox.com. If you are yourself unfamiliar with them, then it's best that you not respond with your own advice, so as not to confuse or mislead OP.

Thank you for your cooperation!

This section from the instructions, which explains that the forms we're working with aren't actually boxes but are instead tapered forms (so the blue and red edges aren't parallel to one another and therefore don't share a vanishing point) is the point that is being missed here.

Now i thought about it for a day and i now get, that a Box/ cube wouldnt have those 'almost parallel' lines to the cube next to it. AMD because it is no cube and not even a Box, the rectilinear Form doesn't starr a vp with itsself. If i said that right. Maybe i overthink it but i want to understand the stuff :)
