Final #2: Six Monocular Depth Cues

This image illustrates atmospheric perspective.  My avatar and the purple alien are sharp and detailed.  The bear in the background is less detailed and fuzzy.  Also, the smoke rising from the care is dense and solid black near the car.  As it rises it dissipates and becomes less dense.  This gives it the appearance that it is moving away and behind the car.
  

This image illustrates linear perspective.  The tree planters and lines in the sidewalk appear to narrow as the recede.  The planters become progressively shorter as they move further away.  This linear perspective is combined with size differences as the planters are also becoming smaller as they move further away.

This image is an excellent example of texture and density.  The bottom shows the corrugated steel floor with wide spaces between the pattern.  As you move up the spaces between the corrugation become more dense.  This increased density makes the floor look further away.  This is an example of objects appearing smaller being further away.

This screen shot illustrates both lighting and shading.  We can see in this image that the light source is coming from the upper left.  The light is most intense in the upper left part of the image and gradually becomes less intense towards the lower right of the image.  The shadowing on the backside of the rock uses shadowing and gives this scene a sense of realism and depth.

This screenshot illustrates occlusion.  The car is sitting in front of the building which is a visual hint that it is in front of the building.

In this screen shot you can see building off in the distance...they appear smaller.  In the foreground you can see my avatar's head...it is closer and larger.  These size differenced are visual clues creating a sense of how close or far objects are and where they are positioned in relation to one another.


This is a blog illustrating the six Monocular Depth Cues. They are screen shots from CloudParty which have been cropped and edited in Gimp.  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
