Open the VRWorx software program by clicking on "Start" and going to "Programs."
The VRWorx title screen will appear briefly.
And then a menu will appear. Choose "Create an Object" and click "OK."
An object module project document window will appear. Click on the "Setup" tab to activate it.
"Source Image Format" has two choices:
1. Image Size refers to the size of the images which will be used to create the object movie. If the image size is not found in the drop down menu, a custom size can be typed in the box after clicking on "Custom."
2. Acquire From determines the source of the images for making the object movie. Choose "PLUG-IN in Image File" if you are loading images from a disk.
The next setting to be determined is the "Vertical Settings." Objects may be captured in a vertical sweep called "rows." Full coverage is 180 degrees. If the desired sweep is not found on the drop down menu, choose "Custom" and type in your vertical sweep. The "Rows" field specifies the number of rows for the vertical capture. Once the "Rows" value is determined, the "Spacing" will be determined automatically. The "Spacing" field cannot be manually edited. The next field can either be "Centered at" or "Start at" and determines where the sweep will begin. If you choose "Start at," then the degree box will be used to specify a starting point.

The next setting to be determined is the "Horizontal Settings." Objects are usually captured in a 360 degree sweep starting at 0 degrees and rotated clockwise. The "Sweep" field determines the number of degrees the image was rotated during the image capture. The "Columns" field refers to the number of images which were taken during the sweep. Once the "Columns" value is determined, the "Spacing" will be determined automatically. The "Spacing" field cannot be manually edited. The "Advanced Views" field determines the direction in which the images were captured and can be either "Horizontally" or "Vertically." The next field can either be "Centered at" or "Start at" and determines where the sweep will begin. If you choose "Start at," then the degree box will be used to specify a starting point.

The next tab on the object module project document window is the "Acquire" tab. Once you have completed all the fields on the "Setup" menu, click on the "Acquire" tab to make it active. Under "Tools" is the "Clear" button. This button can be used to remove a single image from a group of images. The single image must be selected before this button becomes active. The "Single" or "Multiple" settings refer to the way in which the images are acquired to make the object movie. Images can be acquired one at a time or as group. If you choose "Multiple," then the images are added to the frame area at the button of the "Acquire" window in the order that was specified in the setup menu. For this skill development activity we will be using the "Multiple" command.

Once the images have been selected, the "Acquire Images Progress" window will appear. When the window closes, the images will appear in the frames area at the bottom of the "Acquire" menu.
The scroll bar at the bottom of the "Acquire" window allows you to move through all the images to determine that they have been added in the correct order.

The next tab is "Hotspots." This tab allows you to add one or more hot spots which will invoke some sort of action when clicked. The "Tools" menu allows you to add an area in the form of one or more of shapes shown. Color may also be added by clicking the palette image. The image below shows a portion of the object movie with several hotspots added.

The "View" area in the lower left hand corner contains arrows which will allow you to move the image to different views so hotspots can be added in other areas.
   
When the hotspots are chosen, click on the "Hot Spots Properties" button to open up a dialog box.
General information about the selected hotspot can be found in this dialog box. The "Kind" field is a drop down menu which lists the common types of hotspots. The "Type" field becomes active if "Other" is chosen from the "Kind" menu. The "ID" field using numbers from 1 to 254 to identify each hotspot. This is an editable field, so the number can be user specified. The "Name" field can also be user specified. The "Comment" field can be used to add additional identifying comments about the hotspots.
If "URL" is chosen from the tab menu bar, when a user mouses over the hotspot, a click of the mouse will take them to the designated url. To designate the url, the "URL" tab must be clicked and the url typed in the box and the "OK" button clicked. An example is shown to the right.
The next tab is "Effects."
In this area you can add special effects, which are available on the drop down menu next to "Effect."
The next tab is "Compress." This is the final step in creating your object movie and helps you to determine how it should be compressed and displayed.
Click on the "Set" button to bring up the compression settings window. The default settings are shown on the right, but the settings can be adjusted to your specifications.
In the compression window you can also set the color depth and the frame size. The software manufacturer suggests leaving the "Color Depth" set at "24 bit (Millions)." The "Frame Size" will default to the size the images were specified in the setup menu and should remain this size unless the "Crop" command was used under "Effects."
Once all of the above settings have been made, you should click the "Compress" button under "Commands.". A window which shows the "Compression Progress" will appear.
The last tab is "Playback." In the playback panel, you can view your finished object movie and add several finishing touches.
The first is the "Playback Window." This allows you to change the size of the playback window by entering the desired width and height in the appropriate fields.

The "Attributes" set of buttons enables you to do four different operations.

1. "Annotate" allows you to add descriptive data about the movie such as your name, copyright and a description.

2. "Interaction" allows you to set the parameters which will be used by others to interact with your movie.

3. "Animation" allows you to set the parameters which control the two types of animation available for object movies, frame animation and view animation.

4. "Playback" allows you to set the playback options. Clicking on "Preload" allows the movie to load before opening which allows for a smoother playback. Clicking on "Cache data" allows for the movie to retain much of the calculated data which also adds to the smoothness of playback.

The "Poster View" sets a single frame in the object movie as a poster view to be used to identify the movie to your viewers. Click the "Set" button to set the current window as the poster view. Click the "Go" button to view the poster view which was set in the previous step.
The "Initial View" indicates the frame that is first displayed when the object movie is opened. Click the "Set" button to set the current window as the initial view. Click the "Go" button to view the initial view which was set in the previous step.
The interaction box allows you to interact with your object movie just as your viewers will be able to do.
Once all of the above settings have been entered, the movie needs to be "Exported" to function as a stand-alone movie file. When this button is clicked, you will be prompted to determine where you want to save the completed movie file.
Congratulations! You have successfully created an object movie.
