![]() If you view the code running on a web page, you will be able to scroll around with your mouse. The result of the above listing when ran in a browser is shown here: ![]() Note that you can save the Lucas Oil Stadium image above with the name GenCOn.jpg to duplicate this effort. In the code above, we have used a panoramic, 360-degree photo called GenCon.jpg that is in the same folder as the HTML file. This element actually creates a sphere around your entire scene and then paints it with either a color or an image. The sky element is identified with the tag. Within the following listing, we create a scene that only contains a sky element: If you recall from the previous article, an A-frame VR page is created by including the script and then building a scene. Once you have a 360-degree image, you can place it into your A-frame page as the sky background. Read: Virtual Reality Tutorial: How to Build an Android VR App Using 360-Degree Images in A-frame VR I downloaded the above Lucas Oil Stadium image as a. The app includes the ability to then download the images. With P360, an indicator is placed on the screen when you are taking pictures so you know how far to turn before taking each photo. I use the free version of an app called P360 (also called Panorama 360 and Virtual Tours), which was designed for iPhone but also works on Android phones. Once you have taken a full circle of pictures, the app will then stitch them together into a single panoramic view. You keep turning and taking pictures until you go in a full circle. After each picture, you will be prompted to turn and take another. You then take a number of pictures in a row. Apps that take 360-degree images will generally have you stand in one spot. The easiest way to create a 360-Degree image is with an application on your phone or digital camera. ![]() ![]() The following is the 360-degree image I have from Lucas Oil Stadium in Indianapolis taken during the GenCon conference: If you attach the left side of the image to the right, it should flow into a circle. Rather, it is simply a panoramic image that surrounds a central point. If you are unfamiliar with a 360-degree image, it is not a mysterious element. What is a 360-Degree Image in Virtual Reality? For example, I have a 360 photo from the inside of Lucas Oil Stadium in Indianapolis. Granted, there are existing programs that will let you view a 360 degree image in your VR headset or on a web page, so you might wonder what makes doing this in A-frame different? The answer is simple: using A-frame, you can add other objects and models into your view. Below, VR developers will learn how to give your user a 360-degree view of a 360-degree panoramic image. In this article, we will shift away from the constructed environments included in A-frame and instead create the illusion of something from the real world. The article not only showed how to add the various scenes to your A-frame VR solutions, but also presented information on setting various parameters, such as determining the number of trees displayed in a forest. In a second article, Creating a Better Environment in Web-based VR Using A-Frame, the use of pre-created scenes in A-frame solutions was introduced. In that virtual reality programming tutorial, you can see how shapes can be added into a simple VR scene by including a script and then adding a little bit of markup. If you are unfamiliar with A-frame, you can get a quick introduction in the article Web-based VR Made Simple with A-Frame here on HTMLGoodies. A-frame is an easy-to-use library that can be applied in the same manner as HTML tags to create virtual reality (VR) worlds within a web page.
