Unfortunately you're still running into issues.

  • Box 1: You've got the red lines coming towards the viewer.

  • Box 2: Correct

  • Box 3: Red lines coming towards the viewer

  • Box 4: Red and blue lines coming towards the viewer. Alternatively we could reverse how we interpret the box, but that would simply result in the red/blue being correct, but the green lines coming towards the viewer and the box looking kind of wonky, so I don't think that was your intention.

  • Box 5: Correct

The technique that Tofu linked you to previously, which uses the original Y we established when starting each box is, if applied correctly, pretty hard to do wrong. It doesn't mean you'll necessarily understand the idea of which direction is "away from the viewer" and which direction is "towards the viewer", so it's not a perfect solution, but it does give a recipe that can be followed to at least give us useful lines upon which to base our analysis of our results.

Here's a markup of your 5 boxes, identifying the original Y for each box, and where your line extensions are correct, as well as where they're incorrect. I hope that helps - but beyond that, all I can really ask is that you go back and read through the section on this approach Tofu provided earlier and ask you to follow those steps more closely.

Please submit an additional 5 boxes, in reply to this feedback.

Sorry I drew 6 on accident.

That is definitely better, in terms of having all of the sets of lines extended in the correct direction. As such, I am going to ask Tofu to mark this challenge as complete.

That said, there's one critical point you do need to keep in mind as you move forwards - here you appear to have made a concerted effort to draw all of your sets of lines as being parallel on the page, not having them converge together at all. It seems as though you're trying to force the vanishing points that govern these sets of lines to "infinity", in the manner discussed in Lesson 1.

Unfortunately, this is incorrect. We do not directly control where the vanishing points themselves are. We control how the given lines are oriented in space, which in turn determines where the vanishing points ought to be. A vanishing point only "goes to infinity" when the lines it governs run perpendicularly to the viewer's angle of sight - so basically not slanting towards or away from the viewer through the depth of the scene.

That also means that you'd ostensibly only be able to have two out of the three vanishing points of a box "at infinity", which in turn would force that last vanishing point right onto the page, as in 1 point perspective (like the rough perspective exercise). That last vanishing point cannot be put at infinity itself, as this would break the laws of perspective altogether.

Now, that said, this challenge - given that it has us rotating our boxes freely in 3D space - should not really involve any vanishing points "at infinity", since the likelihood of them aligning so perfectly to the viewer is quite slim. Furthermore, it's pretty clear that the way you've drawn these boxes suggests that your intent was not for them all to be aligned to the viewer in such a way.

Keep this in mind going forward, and be sure to incorporate some convergence to your lines when doing this kind of exercise in the future, never having them run so perfectly parallel on the page - and additionally, don't forget the fact that you should be experimenting with both shallow and dramatic foreshortening as explained here.

And lastly - when you do this exercise as part of your regular warmup routine, remember that the line extensions are indeed a part of the exercise, and should thus be included there as well.

Marking this as complete, as per Uncomfortable's request.

Next Steps:

Move onto lesson 2, but take note of everything Uncomfortable mentioned in his feedback.

This critique marks this lesson as complete.

Color and Light by James Gurney

Color and Light by James Gurney

Some of you may remember James Gurney's breathtaking work in the Dinotopia series. This is easily my favourite book on the topic of colour and light, and comes highly recommended by any artist worth their salt. While it speaks from the perspective of a traditional painter, the information in this book is invaluable for work in any medium.
