OCVWarp warps images and videos for planetarium fulldome display. It uses the OpenCV library, hence the name.

Usage

Download the latest Windows or Linux binaries from the Releases tab. You will need to get the ini file and the map file also, and additional dlls in case of Windows, and put them in the same directory as the executable. These are available in some releases, for example v2.00. You can directly double-click on the executable and allow it to run. But if you run it this way, you may not be able to see error or informational messages, if any. Basic usage information is given in the readme. Examples of usage of various transform types are given in the transform types page.

For seeing error messages and information such as frame number and frame-rate of processing, it is advisable to run from a terminal or command prompt, as follows.

On Windows

  1. Open a terminal
  2. cd to the directory where you have downloaded the executable
  3. type the name of the executable and hit enter.

On Linux

  1. Open a terminal, cd to the directory you have saved the AppImage in.
  2. Make the AppImage executable by chmod +x OCVWarp-*.AppImage in the terminal.
  3. Run it with ./OCVWarp*AppImage
  4. (In case there are errors, please install OpenCV's dependencies. The easiest way to do this on Ubuntu, for example, would be to install OpenCV using sudo apt install libopencv-dev )
