1. Occlusion: This picture is an example of Occlusion. My Avatar is in front of a door frame and is closer to us than the door and is blocking our view from the door. In this instance my Avatar seems taller than the door frame even though the door is taller. Occlusion tells us our relative position compared to other objects around us, and shows that since my Avatar is blocking some of the door it is safe to say that my Avatar is in front of the door.
2.Texture Density: This picture is an example of Texture Density. The brick that is closer to us is a lot more detailed and does not seem as dense as the brick on the left hand side that is farther away from us. The farther away the texture (brick) the more dense they seem.
4. Lighting and Shading: This picture is an example of shading and lighting. This house is being hit by the sun on its left side, which "highlights" this side. This side appears to be the brightest, while the left side in the shade is a darker color. This shadow only will be seen by objects that have depth.
5. Atmospheric Perspective: This picture is an example of atmospheric perspective. Compared to the roof that my Avatar is standing on and the grass below which show a lot of detail and are clear, the pipe and building are less detailed and fuzzy. This is an example shows the difference in appearance as a result of light traveling through the atmosphere-- the further the light has to travel the more fuzzy and less detailed an object will be.
6. Linear Perspective: This picture is an example of linear perspective. The walk way that my Avatar is on appears that they are narrowing as it goes into the distance. I drew parallel lines on the side of the walk way to see how far in the walk way goes to give off the impression of the walk way getting longer.
It is a Final exercise from the Immersive Education course that I am taking at Boston College. The course is called Discovering Computer Graphics. For details, visit the immersive BC portal at
