250 Box Challenge - Width of Opposite Ends

11:31 PM, Monday October 18th 2021
I'm about halfway completed with the challenge, and while my lines themselves are improving, I'm still struggling to understand the boxes wholly in 3d space, as the farther end of my boxes never look quite right and the inner vertice is alway off by at least one line.

Reading the challenge page more, I've been trying to wrap my head around this concept of "width of opposite ends" with the farther end being wider yet proportionally smaller, but I'm having a hard time, and it's hard to find an example from my own work or from looking at orientations in blender. I've been experimenting with different implementations of thinking about the lines, but with no real luck.

Does anyone have a good example, resources, or concepts to help me better understand this concept?

Am I just thinking about the wrong approach?

It's really about the ratio of height to width not absolute size. The further away end will be smaller in area/dimensions but the width will be greater in proportion to the height because you are looking at it more face on.

Does this help?

Sort of, perhaps it's because the farther end is overall smaller, or it's too subtle, but it doesn't look like I'm seeing more of the far face. I'm having a tough time visualizing it, and applying it to my current boxes. The visual aid on the challenge didn't really help as it's a top down view. Looking through my boxes so far, I do sometimes see a noticable width to height ratio occasionally, but the inner lines are scuffed, so I don't know if I can trust those as an aid to visualize it better.

Thank you for the response though!

It is relatively subtle depending on how deep the box is and where the vanishing point is.

It's a bit like a spinning disk. A spot on the outside edge is travelling more distance than a spot near the centre for the same angle of rotation.

In this case you can think of the near face being the outside dot. That face is turning away from you faster than the furthest face ( the inside dot ).

Not sure if this helps either but I thought of it so I thought I would say it. Perhaps try drawing a really big box with a lot of foreshortening then measure the edges and see if that helps. Good luck.

I think that kinda visual actually helps a little, and I will try that box idea.

Thank you very much.

When it comes to technical drawing, there's no one better than Scott Robertson. I regularly use this book as a reference when eyeballing my perspective just won't cut it anymore. Need to figure out exactly how to rotate an object in 3D space? How to project a shape in perspective? Look no further.
