Virtual File System
TouchDesigner's Virtual File system (VFS) allows image, movie, audio, fonts, other media and any files to be embedded in a
.toe file. You can open and read them as if they are files in the filesystem. This makes
.toe files more portable if they depend on images or sounds or font files.
It will of course make your
.toe files larger by whatever the hard drive file size is, but one virtual file can be referred to by multiple OPs at the same time.
Internal files can be addressed directly with the
vfs: prefix. Example:
Two python classes give you full access to VFS functionality.
- VFS Class - describes a COMP's virtual file system.
- VFSFile_Class - describes a virtual file contained within a virtual file system.
All Operators that open files, like the Movie File In TOP and Audio File In CHOP understand the VFS syntax. Unlike locking a TOP where the image saved in the
.toe is compressed with LZW, a Movie File In TOP that refers to a
.jpeg file in VFS, it remains fully JPEG compressed.
VFS can hold entire movie files and audio files including H.264 and
.mp3 files. It can also hold
.ttf font files and in some circumstances,
.dll files for the CPlusPlus TOP, CPlusPlus SOP and CPlusPlus CHOP.
Together with the Privacy option (can be set using TouchDesigner Pro only), VFS allows for additional privacy of media built into your TouchDesigner
TOuch Environment file, the file type used by TouchDesigner to save your project.
