Software for creating computer-generated holograms is limited, particularly for "free-space" images like those depicted in media, which are not currently feasible. While there are approximations available, such as tools inspired by fictional devices like the "Angelator" from the "Bones" series, they lack advanced capabilities. A recommended starting point for exploring available software is SourceForge, an open-source platform that offers free software options, although specific hologram creation tools may be scarce. One user found the CGH Construction Kit on SourceForge, indicating that some resources do exist for those interested in this technology.
