CS10001 Lab: 5 points

Fall, 2008 Assignment: 10 points

Objective The student will create a instructions on building a linked object using the Second Life prims.

(search for “Second Life tutorial”)

Background

The real joy of Second Life is the ability to build objects in a 3D environment. Editing objects in Second Life is much like using a 2D graphics package, such as Adobe Illustrator or the graphics tools within Microsoft PowerPoint. To edit and create objects you must be in a site that allows visitors to create prims, such as a sandbox. This assignment is about creating an object through linking prims. A future assignment will involve writing a script for the item to give it a purpose and/or function.

Lab – Experimentation

The lab component for this assignment involves creating a wide variety of objects. Experiment with the various prim objects, settings, and textures. Create 5-10 various prims of different shapes, settings, and textures. Put them in a pile. Take a picture of your objects with your avatar in view.

Report – Instructions to create an object

Use the Second Life prim tools to create a linked object. See the list of ideas to get you started. Once complete, recreate the item and use a word processor to write a set of instructions on how to build the object. Break your instructions into 4 to 7 steps. Use snapshots displaying the object during creation, with at least one picture per step. Follow the format of the example report. Insert page breaks as necessary to ensure the instruction step is on the same page as the corresponding picture. You may copy this assignment writeup document from the class web page, remove the unnecessary content, and change the instructions to match your object. Note: the report filesize could get large as a result of the bitmap pictures.

Grading

You will be expected to demonstrate your instructions to the class, graded on the following criteria:

Effort Creating the object and writing the building instructions

Creativity Originality and imagination in object created and the instruction details

Readability Correctly creating the building instructions report

Presentation Giving a demonstration of your instructions to the class

Extra credit will be given for the following:

• Create instructions to build multiple objects.

• Create a sufficiently complex or useful item, requiring many steps and setting changes. (For a nurse training simulation, I need a good gurney!)

Ideas

The following is a list of ideas to get you started. You are encouraged to implement your own ideas.

Drawing implement I need a good object that is clearly a pencil, pen, paintbrush, or other artistic implement.

Animal In SL, I have a parrot that occasionally rides on my shoulder. Create an animal using the prims available, such as a cat, spider, baboon, komoto dragon, etc…

Weapon There seems to be a big desire to create weapons. Cannon, rocket, sword, gun, etc… The scripting for firing the weapon will be added later.

Vehicle Create a car, wagon, boat, skateboard, surfboard, propeller-hat, jet-pack, etc… The scripting for piloting the vehicle will be added in a future assignment.

Flag Search on YouTube on how to create a Flag in Second Life. You will find a short video tutorial on creating flags using the Second Life prims. You may use any pattern for the flag.

Robot Create an R2D2 or similar looking robot.

How to Create a Wagon in Second Life

Dean Zeller

CS10001

Fall, 2008

Purpose The following is a set of instructions on building a simple wagon using Second Life prims.

Step 1: Create the Wagon Base

1A) Create a Block prim.

1B) Under the General tab, enter Wagon Frame for Name.

1C) Under the Object tab, change the size to 5.0 (X), 3.0 (Y), and 0.1 (Z).

1D) Under the Texture tab, select a texture and color desired for the wagon.

Step 2: Create the Wagon Frame

2A) Select the Wagon Base. Create a copy of the base by shift-dragging on the Z (blue) arrow.

2B) Under the General tab, change the name to Wagon Frame.

2C) Under the Object tab, change the size to 5.5 (X), 3.3 (Y), and 1.0 (Z).

2D) Under the Object tab, set Hollow to 90.0, and Taper to –0.10 (X) and –0.10 (Y).

2E) Move the Wagon Frame down until the Wagon Base is covered.

2F) Select both the Wagon Base and the Wagon Frame. (Select the base, hold down the shift key, then select the frame.)

2G) Under the Tools menu, select Link. The prims will be linked into one object, named Wagon Frame.

Step 3: Create one set of Wheels

3A) Create a Block prim.

3B) Under the General tab, enter Wheels for Name.

3C) Under the Object tab, set Building Block Type to Tube.

[pic]

3D) Under the Object tab…

Set the Size to 4.5 (X), 1.5 (Y), and 1.5 (Z)

Set the Rotation to 90.0 (Z)

Set Hollow to 75.0

Set the Profile Cut to .25 (Begin)

3E) Under the Texture tab, select a texture and color desired for the wagon wheels.

Step 4: Complete the Wagon

4A) Position the wheels towards the front of the wagon, centered with the frame. This will take practice to do it right. Check from multiple angles to make sure it is aligned correctly.

4B) Use the shift-move on the X (red) arrow to create a copy of the wheels prim. Position the second set of wheels near the rear of the wagon.

[pic]

4C) Select the frame and two sets of wheels (using shift-click).

4D) Under the Tools menu, select Link. This will link all prims into one object.

[pic]

4E) Under the General tab, change the name of the object to Wagon.

4F) Under the Object tab, select Physical. This will turn the wagon into a physical object.

4G) Right-click on the wagon, and select More > More > Inspect. The contents of the wagon should display.
