In your logic you should readline ().strip () then split the line by white space and if splits [0] is 'v' then use splits[1] splits[2] splits[3] as X y z coordinates
On a note. Obj format usually just dumps groups of types together All v together all vs together all f together mainly because most sections refer to other sections by Id On Sep 19, 2014 12:55 AM, "Justin Israel" <[email protected]> wrote: > For now, just call self.fileHandle.seek(0) at the start of your > processLine function. > On 19/09/2014 7:43 PM, "likage" <[email protected]> wrote: > >> hmm.. okay, bummer for me. >> >> I thought if in my processLine function, having it to read through all >> the lines in the self.fileHandle would be a different case scenario... >> Now I am totally lost... >> >> >> On Friday, September 19, 2014 3:35:43 PM UTC+8, Justin Israel wrote: >>> >>> To be honest, that rewrite is doing a lot of strange things. >>> >>> You read the first character of the first line and loop over that single >>> character string to see if it starts with 'v'.
