My attempt and the fix after seeing the solution. I wonder why the box concave part has shadows in it? I thought the light source suppose to come from above.. Any feedbacks will be greatly appreciated..

Eager to do the next Ambient Occlusion assignment!

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

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.

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….

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.

My simple AO studies. Also practicing my blending in digital to make smooth gradients.

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.
