Welcome on my new tutorial, In this article i explain you how to open 360 image or 360 Render image and visualize correctly without stretching.
Now, since we have the equirectangular projection image in a standard raster format, we must proceed directly to the creation of interactive 3d panorama by converting an equirectangular projection to a cubic and stretching it over a 3d interactive panoramas virtual cube.
There are several special programs for these purposes, particularly the Pano2QTVR. The main positive feature of this program is that creating a panorama goes automatically, unproblematic to the user and saves him from the need for prior conversion equirectangular projection to a cubic and from the other extra work.
(Click on the play button for start the video tutorial)
Download and licensing of this program are available directly on the developers site:
In addition, there is a demo version, which differs from a fully functional one by supporting the only QuickTime format.
After starting Pano2QTVR, the Start tab opens automatically and offer to create a new project or open an existing one.
To create a new project we must click on the large horizontal button Create a new Project and specify a name and a path for the new project in the new opened window.
This should open a tab Project, which we should provide with a path to an equirectangular projection by clicking on the button with the ellipsis next to the field Equirectangular image and selecting the desired image on the disk, namely the previously obtained spherical rendering.
Then down in the Output format list, select the format for future panorama.
If the panorama will be presented on the screen, the QuickTime video file with extension mov will be an excellent choice. For choosing it, we should specify the value of QuickTime in the Output format dropdown list.
If we want to publish the panorama on the website page, the flash file with a swf extension is perfect. For choosing it, we should specify the value of Flash in the Output format dropdown list.
When a file of the equirectangular projection is selected, the format of the future panorama is specified, the last thing to do is click on the button Create next to Output format to start the process of creating panorama.
When we click Create, the tab Console will be temporarily opened where we can observe the logs of the conversion and after creating, the program will return to the Project tab.
Panorama is ready now and is in the folder, which we have specified before.
If we need to change the default setup of the panorama, such as resolution of the panorama window, the compression ratio, etc., it can be changed using the functions located in the Settings tab.
Interactive panorama is a really good thing. It is worth to be considered not only as a final product for the customer. Its special charm is on the draft rendering stage. With the panorama there is no need of messing about different camera angles trying to cover all elements of the environment to check for errors and compliance with the brief requirements. Panorama is a great tool for synchronization and approval of renderings, for selection of the camera angles of the final renderings. It completely eliminates the need to create multiple frames of a scene on the stage of previews, what can save a lot of time not only in setting the scene, but on the actual computing process for a large number of images.
All have fast renderings and beautiful panoramas!
