Class 10: Monocular depth cues

This is an example of Occlusion. This is where objects that are closer can block objects that are further away. This makes it appear that the object has three dimensional depth. As you can see one tree is closer to my avatar, therefore it is blocking a part of the tree that is farther away from me.

The next picture is an example of linear prospective. This is where an object that is linear, such as this fence, recedes to a point called the vanishing point. In the picture, the horizontal posts in the fence become smaller and smaller as the fence gets farther and farther away.

In the next picture is an example of atmospheric prospective. Objects that are closer to us have greater detail than those that are farther away. In this picture you can see that the trees that are closer to is have much more detail that the trees that are in the distance. The trees that are far away are fuzzy and appear as an outline of a tree while the tree that is close to us has great detail and you can see the leave on it.

The next picture is an example of lighting and shading. Objects that are directly hit by the light source appear brighter than objects that are not being hit by the light source. The light pours over the object and gradually gets darker around the object. In the picture that I took, the pumpkin is the light source. object 1 is directly being hit my the light, making it very bright and the side of it is darker, this creates depth. As you get farther and farther away from the light source (objects 2 &3), the objects appear darker.

The next picture is an example of texture density. As you can see the brick pattern that is closer to me appears to be less dense. But when you look farther away, the brick pattern appears to be more dense. You can barely make out the shapes of the bricks because they look so dense. This is because in 3 dimensions objects appear to be smaller the farther away they are.

The following picture is an example of size difference. As you can see the two torches are physically identical, however because one of them is farther away it appears smaller. This is how 3D environments appear to be three dimensional. Size difference helps determine how close of how far an object is.

This is 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

Final project step2: My completed immersive library/museum

Here is my finished library

This is the top view of my library

This is the main building of the library

This is the lava building

this is the pumpkin spider building that is next to the main building

here is another view of it

this is inside the lava building

above is the view of the top of the lava building

this is a top and side view of the spider building

here is inside of the spider building

this is a side view of the main building and a picture of the big tree

here is the other side

this is the buildingn that has a couch on the roof

here is another view of the couch building

above is a pyramid I made

here is a top view of the main building including the track on the bottom of the picture

this is a good view of the inside of my main building

Final Project Step 2: Building My Immersive Library/Museum

I built my own original immersive library

I started out with a floor

Then i built some pillars out of bookshelves

Then I made some stairs and decided to make my library and open and above ground library

I made the walls out of stained glass to make it more open to nature

here you can see how i have a little pond incorporated to the library/museum

YAY I made a sign

I added some 3D objects such as a tree and a boat!

I built a fun pyramid

I added some art to the wall, a table and a bed!.. everyone needs a rest while they study

Then I added a waterfall to the library!

Then I added a robot!

I created an arch out of library books!

I built another building

this is the floor

here I am building the walls

I made a roof of lava

I built stair to the lava roof

this is my third building I built. It is made of hay and pumpkin. It also has a spider on it

This is creating a library in Minecraft. 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

Final project step 1: Immersive Libraries and Museums

In the article that we read on jied.org it described the mission statement of The Libraries and Museum Technology Working Group, which is is also known as (LIB.TWG). The mission of this group is to maintain and continue the development of the applications that involve library and museum services which are affiliated with immersive education.

LIB.TWG suggests that Immersive Education libraries and museums are essential to the evolution of education. Physical libraries and museums compliment education by providing resources and a cultural experience, however they are limited. Immersive libraries and museums can be used to enrich and personalize the educational experience. In regards to libraries, communications can be more efficient through virtual reality visits and consultations. In regards to museums, the use of virtual gaming can enhance the education and representation of artifacts.

These online resources can help connect and educate people that do not have the resources to do so and the possibilities are endless. For example schools that don't have the funding for a trip to the museum can use an online version of a museum and have the same and even better learning experience. Another example of an application for immersive education is the immersive education study room. This application creates a shared education experience with other students through learning simulators. Allowing easy access to information, other students, and access to collaborative simulations.

This kind of application can be used by younger students, making learning more interesting and fun. It can also be used by college students to make group projects easier to complete by not having to meet up and work around hectic college schedules. These technologies are helpful by improving communications and making it easy to update new information.

I think that the idea of using immersive libraries and museums in education is a great way to enhance the learning experience. Learning in a virtual setting can make learning easier and more fun. However I don't think that virtual libraries should be completely relied on just yet. If the applications do not function properly they can greatly interfere with the learning process and possibly making it frustrating for the students and teachers.
