Overview

In this assignment, you'll start taking your shading skills to the next level by understanding Ambient Occlusion (AO) at a deeper level.

Materials Needed

  • The project image.
  • A red colored pencil, or a digital painting application.

Steps

  1. Download the project file and A) print it out or B) open it in your preferred digital painting application. 
  2. Assuming diffuse light from the sky, indicate in red where you think the occlusion shadows are. Lighter red = less occlusion, darker red = more occlusion.
  3. When you’re done, check the solutions included in the ZIP file. It contains: A 2D solution with ambient occlusion intensity in red. A 3D render to show you where occlusion occurs and better understand the reasoning behind the red areas in the 2D solution.

Duration

This project should take 15–30 minutes to complete.

The one that is floating,i was unsure if there is occlusion shadow or not
@rfrimpong3
I graded myself and I have question please from the notes above, is it implying that only ambient light have Occlusion shadow? Because I thought direct light can also have occlusion shadow in its scene.

I think shadows created by direct light are called "form shadow" or "cast shadow". In this assignment we look at AO, and AO refers to "Ambient Occlusion", specifically focusing on the shadows created by ambient light.

Lighter red are the parts I missed.

Not sure if I'm missing something but I found no 3D version of the worksheet, only a 2D. I see a lot of people here post a 3D version... I feel that AO is a lot easier to understand intuitively than core shadow.

I got confused a bit too, is this what you were looking for? found here https://www.proko.com/course-lesson/practice-simple-ao-study/downloads

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..

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
Bradley Forbush
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.
Bradley Forbush
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.
