Read a GLB file.

GLB is the self-contained binary format of glTF files. This function reads one, extracts the embedded files into the temporary directory, and returns a "gltf" object containing the information in R format.

readGLB(con, verbose = FALSE, ...)

Arguments

con

The connection or filename to read from.

verbose

Whether to report on the process.

...

Currently unused.

Value

An object of class "gltf". This is an R version of the structure represented by a “glTF” file's JSON information.
