Final #2: Six Monocular Depth Cues


Through Meshmoon I explored the virtual world and found different monocular depth cues.
In the screenshot above, size differences can be seen. There are four tables and chairs. These table sets are all sized the same, but by placing my avatar from a different angle, it can be seen that the table closest to my avatar looks big and the table furthest from my avatar look small.



The two screenshots above show occlusion. Occlusion is where an object closer can block the view of the object behind. In the first screenshot, the lighthouse can be seen in the middle. However, as seen in the bottom screenshot, by changing the angle of the view of my avatar, the lighthouse can be blocked by the wooden polls.


In the screenshot above lighting and shading can be seen. 
The light coming in from the window can be seen on the wall, and the window pain can also be seen.
On the grey pillar by the window, the shade of the grey is darker on the right. The light coming from the window is making the pillar's shadow darker, hence the darker grey tone.



The two screenshots above show texture density. Texture density is where the texture of the objects look different from the distance. In the first screenshot, each stone can be seen on the stone wall. On the other hand, in the second screenshot, the stones can barely be seen from a distance. The distance makes the texture less obvious.



In the screenshot above, linear perspective can be seen. Linear perspective is where lines that are parallel, eventually have a vanishing point. In the screenshot above the wood of the bridge eventually cannot be seen at the end because of linear perspective. Since each wood of the bridge is parallel, the bridge vanishes from our sight.



In the two screenshots above, atmospheric perspective can be seen. Atmospheric perspective is where objects that are close appear to be detailed and objects further away appear to be less sharp. In the first screenshot the details of the detail of the mural can be seen since my avatar is close. The shade of the curtains and details such as the bricks of the wall can be seen. On the other hand, in the second screenshot, the details of the murals cannot be seen in a distance, neither can the bricks of the wall can be seen. 

This is a post of me going through Meshmoon Rocket and observing the Six Monocular Depth Cues. 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 http://ImmersiveEducation.org/@/bc
