Hi @Dorian Iten! Here's my simple AO study :). T'was good fun!
Happy new year!
Cheers,

Here is two of three. What about the side of the cylinder? AO or not, and if, where and why?

I did this for this exercise on ambient occlusion and after watching the solution, I am a bit confused, especially about the cube. Like I don't understand why the hole on top should be so dark and why the occlusion shadow spreads so widely on the base plane :/ Maybe watching the modules feedback will help

I did the simple ao assignment in graphite, on computer-print out paper. I assumed there was a lot of ambient light, thereby making the shading and shadow very subtle. I actually broadened the occlusion shadow in this, my 2nd version. (I didn't spread the shadow beyond the circumference of the objects in my first draft). The paper got a bit crinkly when I did this. I had trouble imagining a shadow around the base of the cube, considering light would be flowing all around the object and it was flush with the surface plane.

After watching Module 2 review, I modified my drawing and added a bit more occlusion shadow to the forms. Its still subtle, but I think its much better.

Here is my simple AO study assignment done in graphite.
J haven’t checked the solution yet, but I do feel confident in my thought process.
the cube being close, (touching) the floor plane would be quite dark occlusion but with nothing else blocking ambient light from above, the side planes should stay fairly consistent. The planes in the indentation will likely receive less ambient light as they are in a tighter space exposed to less AL. Also the planes are much smaller therefore will appear to the eye to be darker relative the larger side planes.
the cyclinder and the sphere were much simpler to think about, though I should check the solution before O get too confident….

Revised after going over the solution. In the box, I missed the cast shadows that are sort of tapered due to the multiple directions of light casting shadows from different angles. I also didn’t account for how much “coverage” AO contributes to the shadows. I’m glad this exercise revealed that me.
Also so I can see it in life, I set up a test study subject at work where we have multiple light sources from high up ceiling lamps and skylights and windows as well as white peg board walls. You can see the shadows cast in multiple directions and the inside “walls” of the tape are quite dark.

The cube gave me a bit of trouble ngl, I'm still not 100% sure I understand how the ambient occlusion works with the indent in the top.

Well, here's my first attempt at this. I wasn't sure if I should draw directly on the images, because they already have shadows. Just in case, I drew mine from scratch.

Hello :)
I learned a lot from this exercise but there's one thing that bothers me. In your solution for the block image, upper indented part is much darker than the rest of the shadows and I'm not sure why. I understand that it's inside and not exposed so much to the light as the rest of the cube but it still looks a lot darker.

Nice work, Jeremy. You missed one thing: did you consider that the flat planes at either end of the cylinder would behave in the same way as the flat planes of the cube?

Creating smooth gradients is a challenge. Awesome exercise!

Here's my attempt in Krita. The one thing I want to work on the most is producing clean and render-like tones. I have spent several hours experimenting with various brush sizes, opacities, and hardnesses in combination with layers and masks and identified that I struggle most with compressed gradients, when it's unclear where a gradient starts and ends, overlapping gradients, and non-linear gradients.

Nice work. Creating smooth tones can be easier than you expect! Check out Dorian's great video here: www.dorian-iten.com/smooth-tones

Nice assignment. Difficult to imagine what the shadow will look like. AO Assignment:

Hi Laura. The flat plane (A) at the end of the cylinder would behave in the same way as the flat planes of the cube, getting darker as it gets closer to the table. There would also be ambient occlusion on the platform on the far side of the cylinder (B).
