Method OpenToLibraryFS

xyz/io.go:213–226

OpenToLibraryFS opens object(s) from given file in the given filesystem into the scene's Library using a decoder based on the file extension. The library key name must be unique, and is given by libnm -- if empty, then the filename (only) without extension is used. Supported formats include: .obj =

(fsys fs.FS, fname string, libnm string)

//
//	must have same name as .obj, or a default material is used.
func (sc *Scene) OpenToLibraryFS(fsys fs.FS, fname string, libnm string) (*Group, error) {
	dec, err := DecodeFileFS(fsys, fname)
	if err != nil {
		return nil, err
	}
	if libnm == "" {
		_, fn := filepath.Split(fname)
		ext := filepath.Ext(fn)
		libnm = strings.TrimSuffix(fn, ext)
	}
	gp := sc.NewInLibrary(libnm)
	dec.SetGroup(sc, gp)
	return gp, nil
}

// OpenScene opens a scene from the given file, using a decoder based on
// the file extension in first file name.
