Term I, Perspective I, Week 2

Week of November 16, 2020

For a description of this unit see my Perspective I unit plan. See my Art School Curriculum at Home for a full description of the program.


I probably spent more time studying than drawing this week. I finished Marshall Vandruff’s perspective lectures and the D’Amelio book. Last week I was considering cutting Perspective I short by 2 weeks, but I’ve decided not to do that. I need to practice all the stuff I learned over the last 2 weeks. I finished drawabox lesson 4 and the 250 cylinder challenge, and I’ve started lesson 5. I don’t think I’ll tackle another drawabox challenge this unit, but I can probably finish lessons 5 and 6 (animals and everyday objects). Other than that I’m going to spend time practicing what I’ve learned about perspective.

I got 25 hours in this week, which improves on the 20 hours I got last week. Next week I’ll try to get 27.

Drawings and Critiques

250 cylinder challenge.

Same-colored sets of lines that don’t converge to a single vanishing point indicate construction issues. The hardest part about building these correctly is that the caps of the cylinders have to be perfect squares, and there’s no way (that I know of) to check that when they’re in perspective.

Drawabox insects.

Random perspective drawings. I need to come up with my own assignments to practice perspective concepts.

250 cylinder challenge.

Top right on the first page is closest to correct.

Drawabox insects and random perspective drawing.

Drawabox insects.

Wasps are the most fun to draw, but I’m trying to draw a wide selection.

These are attempts at boxifying household objects (a steamer, and a DVI connector at the top in the right photo). It was really difficult to boxify the steamer because the surfaces of the actual object are so curved. I need to practice doing this so many times that it becomes second nature to see complex forms as simple boxes.

Boxification of a polaroid camera.

It’s hard to get lines to converge correctly when the vanishing point is off the page.

Constructed cylinders

Drawabox animal construction.

Practicing inclined planes that go to a special vanishing point on a vertical horizon line perpendicular to the real horizon line.


I think the only way to improve these is to practice drawing perfect squares in perspective. I can use a plan projection (shown below) to accomplish that.

Drawabox animal demos.

These are focused on construction instead of detail. The tiger doesn’t look bad though. His nose is a little lop-sided. The horse kind of looks like a dog. The muzzle should drop down more.

This is a birds eye view of a perfect square (top) projected into perspective (bottom). The perspective view makes it look more rectangular. Maybe I messed something up. The dot in the middle is where the viewer is standing.

I’m not sure why medium suddenly decided to squash some of these photos.

250 cylinder challenge done! The final few aren’t much different from the first few.

The donkey’s head size got away from me. I think my right hand was covering the body as I was working on the head so I lost my sense of proportion. I like the running rat. It’s hard to construct the faces without any knowledge of animal anatomy.

Drawabox organic form intersection exercise.

The first page doesn’t have a convincing floor plane because of the form floating on the right.

I like both the birds. The top one really has the feeling of a bird. I tried to indicate some feathers but it didn’t work out.
