Examples

Example use cases include scenes like this one, from the planetarium show Cosmic Colors -

Such an effect can usually be created with Adobe After Effects or something similar, using tools like DomeXF Dome master plugin.

Using OCVvid2fulldome and a haphazard collection of video files, without arranging them properly in an aesthetic manner, I got this screenshot, where 10 videos (with some duplicates) are projected at different angles and sizes.

The ini file related to the above is here.

With version 1.6, an ini file similar to the one above results in the image below. We see that the angle mapping has changed, with the direction of the angles specified in the ini file being mapped differently. This seems to be a difference in behaviour between Windows and Linux builds - need to verify if exactly the same code produces different behaviour for the executable on Windows and Linux. The screenshot above is from Linux, the screenshots below are from Windows.

Another use case would be projection of high-resolution, but flat-screen content, for a uni-directional audience as in our tilted dome planetarium, which would have input and output images as below. The following parameters work relatively well, except for some slight distortion at the bottom and top edges -
