HOW TO: The Process of Making a Pano

Section 8: Building the QTVR movie with CubicConverter

Importing the Equirectangular Image into CubicConverter

CubicConverter is the final tool in our arsenal, and it is what is used to convert our equirectangular images into cubic Quicktime VR panoramas. Even if you're not using Quicktime as your viewer, CubicConverter is still needed to extract and cleanup the nadir areas of the images. Launch CubicConverter and then drag & drop the equirectangular TIFF file into the Conversion window:

Click the Convert button to tell CubicConverter to build the 6 cube faces for the pano. When it's done it takes you to the Movie window where you can see your pano and interact with it. But before we can save this pano out for final exhibition, we still need to remove the tripod from the bottom of the pano:

Removing the Tripod from the Image

To fix this we go to the Cube Faces window and select the bottom cube face:

Simply drag and drop the image to the desktop, and then open it up in Photoshop to edit it. Use the Patch tool to quickly remove the tripod from the image:

Adding Your Logo

At this point we could simply save this file and then drag and drop it back into CubicConverter, but there's one more thing that we're going to do. Let's add our logo to the panorama so that it'll be permanently stamped. Assuming you've already created a logo, just copy-paste it into the image, flatten the image, and then save it.

Drag and drop the new cube bottom image back into CubicConverter and click the Convert button. You'll now see your pano with your logo stamped in there, and no tripod:

Setting QTVR Parameters

You're now ready to save your final pano, but before doing this you should set the Movie Settings parameters in CubicConverter's Movie window. Set the JPEG compression quality, the initial orientation settings, etc. You can also set the Fast Start Preview. This allows the viewer to see parts of the pano as they're downloaded. It adds a little to the file size, but it gives the viewer something to see while they wait for the movie to load. Tiling also plays into this, and it also adds a tiny bit to the file size.

When you're done, just click the Save As button and save the .mov file. You've completed your pano!

Exporting as Equirectangular

Now that you've removed the tripod from the nadir you might want to re-export the equirectangular image. Click the Conversion tab, and in the Convert To pop-up menu at the bottom select Equirectangular Image. Click the Convert button to convert the 6 cube faces back into an equirectangular image that you can use with other display technologies such as PTViewer or Immervision's PurePlayer viewer (discussed in the next section).
