Hey all,
I was wondering if it would be possible for someone to show an example of re-writing a file but skipping the header. Let’s say for instance that you have some tabular data but have a header at the beginning of the file that you don’t want…just the tabular data. I’m basically trying to re-write a .ply file into an .xyz.
Here is a snippet of the file:
ply
format ascii 1.0
comment VCGLIB generated
element vertex 7513550
property float x
property float y
property float z
property float quality
element face 0
property list uchar int vertex_indices
end_header
1.98723 -0.861066 0.165241 90
1.98248 -0.85899 0.166504 87
1.97935 -0.861066 0.166289 89
1.97517 -0.860441 0.170998 90
Any help is greatly appreciated!
Why not use a filestream/stringstream and skiptostring?
fs = openfile "some.ply"
skiptostring fs "end_header"
That should position the stream to point just after that line.

-- example ---------
ms = MemStreamMgr.openFile "C:\\file.ply"
ms.skipBlock "ply" "end_header" -- skip the header
ms.skipSpace() -- skip space, tab, and newlines
data = ""
while not ms.eos() do data += ms.readLine() + "
"
MemStreamMgr.close ms
expFile = openFile "C:\\file.xyz" mode:"wt"
format "%" data to:expFile
close expFile; free expFile
Thanks for the help!
@ Eric i had tried both skipToString and skipToNextline…but i had them in the wrong spot! Once i moved it as per your example it worked perfect!
@Panayot Thanks…going to study your approach a bit more to see if i can learn something!
Thanks again for the help…i’ll try and post it here once i clean it up a little…maybe it’ll be usful to someone else.
