In this lesson, Peter Han shows us how to transform organic forms into mechanical designs using linear perspective. Starting with an organic object, like a peccary skull, we observe its structures and landmarks to visualize how to convert its shapes into mechanical forms.

I found this very hard, but after a few failed attempts, I managed to do this. I don't understand how mechanical hinges and joints work, how to connect things in a way that makes sense and I don't know how to detail this stuff further (apart from the details I stole from Peter Han)
But I will try to do these from time to time throughout the year, because I want to get better at drawing mechanical stuff.

Awesome lesson and demo. I learnt that understanding the forms is still an important aspect in drawing organic stuff. It was also comforting to hear that the forms themselves don't need to be perfect, because it is just a method for us to understand the object's form better.

Really inspiring lesson. I did this one from a picture I took at the museum. I’m going to have to look into more references for mechanical details. I kind of ran out of ideas for how to accessorize.

Here is the late homework! Just catching up with all the videos. I am sharing on social media the making of these homeworks to promote the course. You can see the sped up timelapses here: https://www.instagram.com/reel/DGO0WGmu8CM/?igsh=MWo3YXJ2cXZhejR4Yw==

I am really enjoying this lesson. It inspired me to pull out George Bridgman’s book, The Human Machine. I drew a few of the drawings from the book. I drew a couple of Asaro heads in slightly different perspective views. The Asaro head can be found on Sketchfab. One of them, I somewhat joined the mechanical neck drawing from the Bridgman book. The head at the bottom right was drawn from the Bridgman book, combining the head to the neck mechanism drawings using a bit of imagination. Thinking of modern mechanical parts, I pulled up an image of a pneumatic machine part and played around with the idea of a pneumatic mechanical jaw. I have attached the picture that I referenced. I drew 4 images as the perspective was a bit off on the first two on the right side bottom. I imagine that I will be coming back to this lesson a lot. Thanks a lot for the inspiring lesson.

Had fun with this, I did a couple organic sketches followed by about 5 quick boxy ones before finally adding a bit of mechanical detail. Would strongly recommend sitting in the structural phase for multiple iterations before attempting anything more. Very impressive to see Peter do this effortlessly, truly inspiring!

Great study! Really captured the proportions

I tried drawing a goat skull from reference a couple of times, and then I tried turning it around in my head and draw a mechanised version from memory. I think it turned out alright, but I didn’t really get a good grip on the 3D form of the skull. I think that a 3D model, or the real thing like Peter had, would have helped a lot. The references were all too similar and they gave me an idea of the silhouette instead of the 3D form.

Really great demo! As someone interested in learning more about approaching sci-fi design, I found this very informative.

This demo by Peter is an artwork in its own right.

The living legend, Peter Han. That was amazing to watch. I'm going to find something my beginner butt can turn from organic to mechanical, and practice this.
Thanks Marshall. This perspecrice course has been awesome so far

He made it look so easy too! translating the shapes is hard enough as it is, and he did it by just looking at the skull for a few seconds! one day...

Here, I took a shot at drawing a skull I found on Sketchfab. (https://sketchfab.com/3d-models/chamois-rupicapra-rupicapra-8c279797eed148ddac38f6e78b73e27f) I also explored how hydraulic mechanisms work on a digger and applied that concept to the skull. I really enjoy this way of thinking—studying organic forms, mechanizing them, and turning them into an interesting design.

This is really cool! Love all the exploratory sketches too! I'd love to see this head on a full robot

Thanks for having Peter on again Marshall for doing another fun demo on how he uses organic forms into perspective. This was such a fun watch.

Thank you for the demo, it feels so well timed! It's really interesting to see what we're currently learning extended in this way.
