Slideshows and Multimedia

Add Multimedia Content To a present4D VR-Suite Project

The 360° media linked by HotSpots represent the Locations in the virtual world you are building. This world is further enhanced when you add multimedia content including photographs, videos, sound files, 3D objects, reports and other documents as .pdf files. It is even possible to create multiple choice quizzes and add them to specific Locations in your project. This content is displayed as Slideshows associated with specific Locations and accessed by the user via InfoSpots.

present4D includes a user-friendly process to import both 360° media and the content for Slideshows. You can define Slideshows when you first create a project or anytime later to enhance your project with more details. Slideshows can also be set up externally using the Advanced Import method. While this method can be very fast, it requires the user to follow strict rules regarding file and folder name conventions.

Opening and Closing of Slideshows

Slideshows appear in the project as clickable “Infospots” that are labeled by the Editor.

In VR Mode:

  • To open a Slideshow, use a VR click on the InfoSpot.
  • To close a Slideshow, rotate your head by 90 degrees to the side.

In non-VR Mode:

  • To open a Slideshow, click the left-mouse button on the InfoSpot.
  • To close a Slideshow, click the X button in the upper-right corner of the Slideshow window.

Automated Navigation Buttons

All the navigation buttons for a Slideshow are automatically shown or hidden, as needed. When there is multiple content in a slideshow, such as multiple photographs, the slideshow starts playing automatically. The user can also manually navigate through the content with left and right arrows.

Using Videos in Slideshows

A video played in a Slideshow has the standard controls for play, pause, restart, and a timeline. To advance the video forward, click onto the desired position in the timeline.

Duration Setting for Slideshows

For Slideshows with multiple images or documents, you can adjust the length of time the files are displayed.

  1. Start Editor Mode
  2. Launch the iMenu
  3. Select the Settings tab
  4. Scroll down to Picture Time
  5. Choose the number of seconds you want each file to be displayed

For advanced users: To use the Individual setting, you can set individual durations for each Slideshow in the media.xml.

Related link to the settings: Picture Time.

Videos run until the end, then switch to the next content.

Add Slideshows and Multimedia Content

There are two ways to import media files into your project and create a Slideshow:

  1. Use the Step-by-Step Import process from the iMenu (in present4D’s Editor Mode) and create Slideshows for each Location
  2. Use the external, Advanced Import process to copy media files into the correct folder structure using Windows Explorer (file manager) and import the entire folder structure at once

Both methods require use of Windows Explorer to select files. This must be done when not using VR goggles.

Step by Step Import

The first steps are to open your project, start Editor Mode, open the iMenu, and select the desired Location where you want to add a Slideshow:

  1. Start Editor Mode
  2. Launch the iMenu
  3. Highlight the name of the Location where you wish to create a Slideshow.
  4. Select the Arrow in a Circle icon to the right of the name. This causes the selected Location to be loaded.

  1. Choose the tab Media from the top of the dialog box.
    • Choose from the options on the bottom of the dialog box to add that type of media files to your project.
  2. Choose the Slideshow icon to make files available to the user by clicking an Infospot. This causes Windows File Explorer to open so you can select the desired files.
    • Browse to the desired Location on your hard disk and select the media files to be inserted into this Slideshow. Choose one or more files to open with the following extensions: Image files such as .jpg, .png, Acrobat documents in .pdf, or video .mp4 files.
    • Enter the name to be used for the Infospot for this Slideshow (the file name of the first item is the default name). See also: Media Types and Dimensions for Slideshows
  3. Choose the Sound icon to add a looping sound effect to the Location.
    • Follow the steps described above for Slideshows, except choose a .wav file to play.
    • The sound loops continuously as long as the Location is displayed.
    • If you add two sound effects, they play simultaneously.
    • Sound added with this feature will also continue to play even if a video file is added that also has sound.
    • See also: Audio Files
  4. Select the POI icon to add a label to the Location.
    • The label consists of a headline and an optional sub-headline.
    • Click the green check mark or press the Enter key to complete the label.
    • You can add multiple POI labels and drag them to any position.
    • (Also available in VR edit mode)
  5. Select the Quiz icon to create a multiple choice quiz and enter the name for the quiz slideshow button.
    • Read more about the Quiz
  6. Choose the 3D icon to add a view of a 3D object to your project.
    • Follow the steps described above for Slideshows, except choose the folder that contains all the files for the 3D object, including textures.
    • A view of the 3D object is opened in a circular window where it can be rotated in 360°. See the section, below on 3D Objects for more information. See also 3D Object Viewer

Advanced Import

Experienced users who are already knowledgeable with present4D folder structure may want to save time by gathering all their slideshows and other multimedia content together externally. In this case, you manually create subfolders under the folder for the desired Location. When you open the project in present4D, it automatically adds the multimedia content to each Location.

Follow the chapter Import - Advanced

Media Types and Dimensions for Slideshows

Audio Files

See also: Codecs: Codecs and File Formats

3D Directional Sound

  • Sounds are stored as 3D directional sounds.
  • In VR mode, the position of the sound is acoustically located in the 360° image and moves with the head rotation.
  • The sounds can be moved like HotSpots by dragging the speaker icon in the 360° view.

Background Sounds - Advanced

Using the Advanced Import process it is possible to define a background sound like this:

  • Any audio file with a name that ends in _bg will be used as background sounds.
  • Background sounds are played in stereo, like for example a piano playing in the background.

For example:

  • If the filename is piano_bg.wav, the sound will be played in stereo
  • If the filename is piano.wav, the sound can be positioned in 3D

3D Object Viewer

3D Objects Overview

_images/3d-object_40proz.jpg

Similar to a Slideshow, it is possible to add a view of a 3D object to your project. Each 3D Object view can only contain a single 3D object and these files cannot be mixed with other media files.

In VR mode, you rotate the 3D object by moving your head. To close the 3D view, our head to the side. In non-VR mode, rotate the 3D object by dragging it with your left-mouse button.

Size of 3D Objects

Please note that 3D models are preloaded when changing the Location. Since 3D models may have a large amount of data, it may slow down the performance, especially with mobile devices. To avoid performance issues, it is recommended that you do not add several large 3D models to any one Location.

3D objects are created with a large number of small surfaces, called polygons. The maximum number of allowable polygons in 3D objects placed in a present4D presentation depends on the hardware that will be used to view the project. Here are some rough guidelines:

  • To be viewed on smartphones or other mobile devices: Use a maximum of 150,000 polygons per model
  • To be viewed with an Oculus headset: Use a maximum of 15 million polygons per model
