parameter	Details
attribIndex	the location for the vertex attribute to which the vertex array will feed data

	# Please note, the commands below will create unreadable files and should be
	# used for testing file size only. If you're looking for something that has
	# lines in it, use /dev/urandom instead of /dev/zero. You'll then be able to
	# read the number of lines in that file using `wc -l large-file.1mb.txt`

	# Create a 1MB file
	dd if=/dev/zero of=large-file-1mb.txt count=1024 bs=1024

	# Create a 10MB file
	dd if=/dev/zero of=large-file-10mb.txt count=1024 bs=10240
