Creating Animated Desktop Wallpapers with Second Life Images


In a recent post we covered using Second Life photos as desktop wallpapers, and following on from that, we're now going to discuss how to create animated desktop wallpapers with a Second Life photo. There are a number of ways this can be done, but in this tutorial we'll be using Wallpaper Engine which can be found on Steam.


  As with all things there are pros and cons with using Wallpaper Engine. The pros include:
  • The price. Its costs just £3.00 (approximately $4.00). 
  •  It also takes up vey little CPU usage. Infact its impact on computer performance is negligible. Above is my PC's performance with Wallpaer Engine running. CPU usage jumped 2% when taking the screenshot. 
  • Wallpapers can be shared.
The cons of Wallpaper engine include:
  • Steam has to be opened to access Wallpaper Engine. Once its open however Steam can be shut down.
  • To share wallpapers users have to jump through a few hoops, which can be off putting. Once a wallpaper has been added, anyone  wanting to use it has to add the creator as a friend, although this only appears to be the case with new users.

The above video is a recording of the wallpaper we're focusing on in this tutorial, and a few more can be found at Lusus Studio. If you'd like to grab any of the wallpapers you see there, you'll need to install steam, buy Wallpaper Engine, then find my profile and add me as a friend, (as I say, lots of hoops to jump through). If you have any trouble with this, feel free to contact me in Second Life (Lusus Saule).

Using A Second Life photo

There are a number of features in Wallpaper Engine that can simply be added directy to a Second Life photo (such as water ripples etc). However in the wallpaper here the animation is the rotating sails on the windmill, so we need to think ahead a little.


For this wallpaper we need two images. The above photo was taken in the usual way.


Before taking the second photo the windmill sails were temporarily derezzed, making sure the camera position did not change.


The first image was then added to Gimp, an alpha channel added, then using the paths tool the sails were isolated from the rest of the image. The image was then cropped to content and exported, making sure the gamma option was selected so the background remained transparent.

An important point to keep in mind before removing the background from the sails is, if one of these images is edited in a particular way, such as resized, or colour enhanced etc, the same should be done to the other, to ensure they match exactly.

Creating A Wallpaper In Wallpaper Engine

Now we have the image of the windmill without its sails, and the sails as a separate image, we can use them to create the wallpaper. Assuming you have installed Steam as well as Wallpaper Engine we are ready to go.


1/ With Wallpaper Engine running, click on the hidden icons arrow to the right of the taskbar. Right click on the Wallpaper Engine icon and from the drop down list select Create Wallpaper.


2/ Wallpaper Engine will open and the above window will appear. Cick on Use a Template.


3/ This window will now appear. Name the wallpaper, select 2D Scene as well as the resolution. Hit OK when you're ready.


4/ A blank window as above will appear. To add the image of the windmill without the sails hit Add Asset.


5/ From the above list select Image Layer, highlighted in red. Hit OK when ready.


6/ After navigating to where the image is located on your PC and selecting it, the window above will appear. Hit OK.


7/ The image has now been loaded into Wallpaper Engine.


8/ Follow the same steps to add the image of the sails to Wallpaper Engine. They will appear in the centre of the image window.


9/ To position the sails, drag the yellow square. hold down Ctrl and scroll with the middle mouse button to zoom in. Hold down the left mouse button to drag the image so you can see the area you're focusing on.

Animating The Sails


1/ To add an effect to the sails image, make sure its the selected layer, and to the bottom right of the window, under Effects, hit Add.


2/ From the Add Effect list select Spin then hit OK.


3/ The sails should now be rotating, although they may not appear correctly.


To fix this, under the Mode drop down list select Vertex.



4/ To the bottom right there is an option to edit the speed of the sails' rotation. Adding a minus sign changes the direction of the rotation.

Publishing To Wallpaper Engine


 1/ The wallpaper is now complete and is ready to be published to Wallpaper Engine. To do this, under the Steam menu select Prepare Wallpaper for Publishing.


2/ This window will appear and is pretty much self explanatary. Simply fill in the information about the wallpaper including its age rating. A snapshot of the wallpaper will be needed but that is a straightforward process of hitting the Take snapshot button and drawing a square over part of the wallpaper image.

3/ When you're ready hit the Publish button and you're done. Your wallpaper is ready to use and to share with friends.

As this tutorial shows, creating animated wallpapers from a Second Life photo is quite an easy process and can add another dimension to the creativity of Second Life photographers. There are some very imaginative Second life images out there, and it would be amazing to see some of them as animated wallpapers.

Using Second Life photos As Desktop Wallpaper



 
Second Life offers infinite opportunities to create stunning images, and there are plenty of expert photographers who make full use of this. However, once those photos have been snapped and tweaked in various graphics software, uploaded to Facebook, Pixel VR and Flickr, what then?

One possibility is to use these Second Life photographs as desktop wallpaper, perhaps on your own computer, or to share with others. One clear advantage of sharing is firstly its a nice thing to do, and secondly it helps to promote your creativity as a photographer as well as other skills you may have.

When sharing images as wallpapers there may be some concern about people misrepresenting  your Second Life photos as their own, but this is easily dealt with by adding a signature or watermark to the image, and a text document outlining a license agreement can be included with the image download. Creators could also include in the text document information about what they do. (A PDF document can include live links to a Marketplace store or website as well as an SLurl to an in-world location).

Desktop Wallpaper Software


Changing the desktop wallpaper on a PC is very straightforward, but there's no reason to stick with just one image. There are a number of software options that will automatically change the wallpaper at prescribed times, so any number of Second Life photos can be used in rotation on the desktop.

Possibly the best known wallpaper software is Bionixwallpaper, and whilst it has a lot of bells and whistles, there are a number of downsides to it. The most prominant of these is that, when it starts for the first time, it will grab every image on the PC and use them as wallpaper before you have time to stop it and create a designated folder. To find out a little more about Bionix for yourself, there's a short intro page.


A more lightweight option is Any Wallpaper. Whilst its free to download and use there is a donation button for those that feel the developers deserve to be rewarded for their work. When Any Wallpaper runs, a window (top image) will open where a folder containing wallpaper images can be selected. Clicking the Options button will open the window above where you can change the duration of each wallpaper, and the order they'll appear in.

Where To Share Second Life Wallpapers

Second Life wallpapers can be shared anywhere online where photos are usually uploaded. This includes Flickr, Pixelvr and Deviantart among others. There are also numerous Facebook groups devoted to Second Life photography, so perhaps these could also be used to share wallpapers. (If enough interest was expressed a group dedicated to Second Life wallpapers could be created on both Facebook and Flickr).

In the spirit of sharing I've created a zipped folder to download containing the ten Second Life photos on this page.  They all have a resolution of 1920 x 1080 and are Jpegs. Feel free to use these images, but do not edit them or pass them off as your own, although resizing them to fit your screen resolution is fine.

The folder is stored on Google Drive, so you can be sure it doesn't contain anything nasty. Click here to download the folder, and  enjoy using any or all of the images as desktop wallpaper.

How To Create A Facebook 3D Image Using A Second Life Photograph

One of Facebook's recent innovations is allowing users to create 3D images generated from a single photo. Whilst this is usually done using a standard photograph, it also works with images captured from Second Life. Although Facebook posts can be embedded into websites,  if you can't see the 3D image below, try clicking the link here.


The image we're using for this tutorial shows a sculpture called 'Invisible' by the renown Second Life artist Mistero Hifeng. It can be seen at the Lundy Art Gallery and Museum. Click the link to visit.

What Is A Depth Map?

A depth map is an image that maps out areas of a corresponding photograph in light and dark tones. Facebook uses these depth maps to calculate what parts of an image are in the foreground and which are receding. The lighter a tone the nearer to the foreground it is, and of course the darker the tone the more it recedes. This information is used to produce a parallax effect, which in turn creates a sense of 3D.

The above image is an example of a depth map and corresponds to the image below. When both are uploaded to Facebook together, they generate the 3D image.

For a standard photograph, its depth map would need to be created in software such as Gimp or Photoshop, which can be a slow and involved process.

However, both Firestorm and the official viewer (and maybe others) have a built in function to create depth maps, which means turning Second Life pics into 3D images is greatly simplified.

Tips On Creating A Good starting Image 




When taking snapshots in Second Life to turn into good 3D images it helps if a few things are kept in mind. For more detailed information on this visit LAB3D on Facebook which is a group for people who create 3D images. The tips below however will help to get you started quickly.

Firstly, large images work better than smaller ones. The recommended dimensions are 3024 x 4032px (portrait) or 4032px x 3024 (landscape). Having said that, smaller image sizes can sometimes work well, (the image used in the example here, after being cropped is smaller than the recommended dimensions), so a little experimentation might be needed.

Images that have a clear point of focus work much better than ones that have a busy and cluttered subject matter.

As explained above, the illusion of 3D is created when Facebook uses the darker and lighter areas of a depth map to create a parallax effect. Although you may intuitively aim for a large parallax effect by creating big contrasts in depth map tones, the best images use subtle tone differences.

For this reason its best to create a depth map with not too much dark and light contrast. Also, tones that are too light or too dark should be avoided. A range between the hex values of #202020  for dark tones, and  #707070 for light areas is ideal. 

Creating A 3D Photograph Using A Second Life Image


1/ Take the snapshot in the usual way in Second Life, but keep the Snapshot window open afterwards, and don't move your camera. 

In the Capture drop down menu select Depth, highlighted in red above. From the Filter drop down menu select Negative highlighted in blue above.

If a preview of the depth map doesn't show, hit Refresh

When saving the depth map image select Save As to make sure it saves correctly. Its also wise to view it once saved, because if it hasn't saved correctly it will just save as a standard image.

If there is movement in your subject matter, such as avatars walking or dancing, before you take any snapshot check the Freeze frame option, highlighted in green above, to ensure you use the same static image for the photogragh and depth map.



2/ Load both the image and depth map into Gimp as layers.


3/ Using the Rectangle Select tool, highlighted in red above, draw a rectangle around the area of the image to be used.  

4/ Now select Image > Crop to selection

5/ Give the depth map image (not the photograph) a slight blur by selecting Filter > Blur > Gaussian blur

6/ Export each layer, giving them either a png or jpg extension. 

How the depth map image is named when its exported is important. It should follow the example below:

<image name>_depth.png

Therefore, if you have an image named Portrait the two files will be named: 

Portait.png = the photo file
Portrait_depth.png = the depth map file.

Naming the files this way lets Facebook know the images will be used to create a 3D effect.

Uploading The Images To Facebook


1/ Open Facebook and go to your timeline. At the top of the page click on Photo/Video so you see the above.


2/ Open the folder where your two images are located. Hold down Ctrl, click on the first image then the second so both are selected. Now drag them to the space above which says 'Whats on Your Mind?' 

Its important you drag both the image files together to let Facebook know to use them to create a 3D image.


4/ The images will now start uploading.



5/ You'll now see a window similar to the above whilst Facebook creates the 3D image.



6/ Once the 3D image has been created click on the Post tab at the bottom of the image window.



Your image should now look 3D and be ready to share with the world. 

Using a Second Life viewer to create the depth map saves a lot of time and effort, although it does have its limitations. For example, its not easy to limit the depth map's light and dark tones, which as noted above would produce a better parallax effect. The depth map can however still be edited in software such as Gimp or Photoshop to add or change tones, if you have the patience to do so. 

On a final note, if you want to create 3D images with RL photos, take a look at OmniVirt. This website allows you to upload an image, from which a depth map can be generated. The depth map will probably not be perfect since this function is still in beta and will need further editing, but this is a much better way of creating the depth map than starting from scratch.

Using A Second Life Stream To VJ Live On YouTube


Setting up as a DJ in Second Life is something many residents have done, but what is less common is using a Second Life stream to VJ on YouTube. For those that may not be aware VJ means visual jockey and refers to someone who in one way or another creates imagery to match the music they play. In spite of the lack of Second Life residents who VJ it is something worth learning and maybe bringing in world.

VJ Software

In order to VJ some software is needed. Firstly there is the stream that can easily be rented in Second Life, then there is the software to play the music. All DJs will be aware of these two items but to VJ add to the list music visualisation software and something to broadcast live to YouTube. 

One last thing you'll need is a verified YouTube account that is registered for live broadcasting, which usually takes about 48 hours to set up. To start go to your YouTube account and click on the movie camera icon and select Go Live, then follow the instructions.

Plane9 


There are many music visualisers available, some free and some commercial, but a good starting point for a new VJ is the free Plane9, and for that reason we'll be using it for this tutorial. Plane9 is intended as a music visualiser for music played on a PC but when used with broadcasting software its possible to connect it with YouTube Live. Also, Plane9 can act as a screensaver for those that like such things.

OBS Studio


OBS Studio, or Open Broadcaster Software connects to the music visualiser then streams the imagery to YouTube. As with all software mentioned here, there are alternatives to OBS Studio, but since its free and works very well, this is what we'll be using for this tutorial.

You may have noticed that there are two streams involved here, one for the music and another for the imagery. OBS Studio could be used to stream both but in order to stay within YouTube terms of service music should not be streamed to its platform. Instead we're going to add a link to a Second Life music stream, which will be explained later.

Using The Second Life Stream To VJ Live On YouTube

Assuming you've downloaded and installed the software already mentioned, and your YouTube account is verified you can now begin to VJ. First, start up your music streaming software then follow the instructions below.

Starting Plane9


1/ Start up Plane9. Under the list of software installed on your PC there will be three choices for Plane9. Select Configure Plane9.



2/ When Plane9 is running it will look something like the image above.


3/ To the right of the window will be a list of playlists. Hit New Playlist tab.


4/ In the main window area there are different kind sof visualisations. Some are Foreground visualisations....


Some are background visualisations....


And some are transitions. A visualisation in Plane9 will be a random combination of foreground and background imagery and a transition will determine how Plane9 moves from one visualisation to another. Therefore a playlist should consisit of as many foreground and background visualisations as you like, plus a number of transitions.

To add any of the above to a playlist click on them in turn so a tick to the lower left of each thumbnail is circled in green.


5/ Once you've finished selecting, double click on the playlist name to rename it.


6/ To run a playlist, hover the cursor over its tab and click the screen icon that will appear.


7/ A new window will open showing the visualisations, which will randomly change. They should respond to music playing on your PC. This window can be quite large so you may want to resize it by dragging its edges. Since there is no option to stop it being always on top of other windows it can be useful to drag it to the corner of the screen.

Starting OBS Studio


1/ When OBS Studio starts it will look similar to the image above. We want the Plane9 image window to appear in the main area of OBS Studio so it can be broadcast. To do this click on the + icon, highlighted in red, lower left.


2/ A window as above will open where you can name the source. In this case Plane9 will be the source. Click OK when done.


3/ There will now be three drop down menus to make selections from. In the first select Capture Specific window. From the second menu select the Plane9.exe window, (which may also show the name of the visualisation that is running). In the third menu, Match title, otherwise find window of same executable has been chosen. Hit OK. The Plane9 visualisation window should now be visible from within OBS Studio.


4/ If the visualisation doesn't take up the entire viewing area click on it so a red border appears then drag it until the whole window is filled.


5/ The above image shows how the visualisation should appear once dragged to fill the viewing area.


6/ To be sure OBS Studio does not broadcast any music to YouTube click on Settings to the lower right of the main window then in the window that appears select the Audio tab. Now make sure all audio options are disabled, as in the image above Click OK when you're done.

Connecting OBS Studio To YouTube

Now that OBS Studio is up and running all we need to do is connect it to YouTube so that what appears in the OBS viewing area will be broadcast live.


1/ Go to your YouTube channel and click on the movie camera icon.

2/ Now hit Go Live.


3/ Since we're not using a camera you should see a message like this, but don't hit Exit.


4/ Towards the lower right of the same screen should be the above button. Click this.


5/ The above information will now be visible. Drag the cursor over the Server URL space and copy it.


6/ Back in OBS Studio, hit the Settings button to the lower right of the main window. In the new window that opens select the Stream tab. Make sure Custom Streaming Server is selected in the very top drop down menu.

Now paste the Server URL we copied from YouTube into the URL space. Keep this OBS Studio window open.


7/ Back in YouTube, reveal the Stream name/key and copy it. Hide it again so no one can see it, since anyone with that key can broadcast on your channel.


8/ Back in OBS Studio, paste the stream key in the Stream key space. Now hit Apply then OK.


9/ Towards the lower right of OBS Studio is the Start Streaming button. Hit it when you're ready.


10/ In YouTube you should now see something like the above with a green live streaming button to the top left. The stream may not show immediatelly on YouTube, so refresh the page if you need to.

Linking To A Second Life Stream 


Since its not wise to broadcast music on YouTube, a work around is to paste a link to your Second Life stream on the YouTube live broadcast page.

1/ Paste the URL of your stream into your browser so you see something like the image above. Right click on the Listen tab and select Copy Link Location (the wording of this may change depending on your browser) from the drop down list. 


2/ Add some info about the live stream to the appropriate area on YouTube and paste the link to your music stream. Now when anyone clicks the link a window similar to the above will open allowing them to listen to your music whilst watching you VJ live.


Thats essentially the basics to getting started VJ-ing with a Second Life stream on YouTube, and although there is more that can be done whilst VJ-ing, this will be covered in later tutorials. 

As a final note to those concerned that VJ-ing on YouTube during a Second Life DJ set may cause lag, the above image shows my frame rate during a recent VJ test. In fact streaming to YouTube at least in this instance didn't seem to affect Second Life at all.

Below is a vid showing a recording of a test VJ session of YouTube, sadly with no sound, but it gives an idea of what can be done.


Good luck with your own VJ sessions and come back for more tutorials soon.
