i am not exactly sure what you mean, but probably, there is a misunderstanding, so i think i'll just show you what i am trying to achieve (see file attached).

a bunch of vertices should be...

But if I am right, a complex-hull algorithm would just compute a hull around the whole group of verteces. Actually I am looking for a triangulation-algorithm for these verteces, though..?

There are 4 verteces defining a rectangle, but within this rectangle, there is just a bunch of verteces at no specific order.
Could you give me a hint on how to solve this problem with <cmath>?

hi,

i am trying to solve to following problem:
out of a given number of vertices i need to calculate
a triangulation and receive the edges.
is there any library that would help to achieve this,...

Hi,

I am trying to automatically build 3d cubes from pictures. therefore I followed the lib3ds "cube.c"-example (see http://www.lib3ds.org).
I don't understand how I can achieve, that the fourth...

thanks,
i'll try that library

hi,

is there a possibility to use regular expressions within the srtcmp-function?

thanks,

but sending the password to /dev/pts/1 prints it but does not
make su accepting it..?
maybe i am doint something wrong?

yes it does, so i'll have a look at the expect source-code...
it's c though, and im not very good at thinking in pure c-code,
but c++-code...
thanks anyway!

hi,

i'm trying to execute some programs from within a c++-program, where i
ask the user to specify the root password and would like to execute the
command then with "su -c "the-command", via...

wow, thank you so much!! thank you all!
finally it works and i got it to search for
the hex-codes passed!

thanks!

ok, so i tried this, but this always gives me a negative output, except if i set all the
integers for the HexString to 0. I do not see why, can anyone give me a clue?


#include <iostream>...

@t3chn0n3rd : thanks, but i do not just want to browse some files and edit them..

oh, thanks ZuK, i didn't refresh the webpage, so i didn't see your answer before
i replied to the post.. :)

yes of course, and i do want to learn, that's why i did not just say "give me some code to do this".. :)
so far i tried to write such a procedure in a file test.cpp

#include <iostream>
#include...

thanks!

but how do i compare binary-read input and a hex-string?
i can't think of that point...?

well... nice to know..

would you tell me how, then..? :)

hi,

is there a possibility to find a hex-code string within a binary file
and get its position in that file?

thanks,

toby

yepp, it works, thanks a lot!!

thanks! well... and that's it then? bash-completion on cin?

hi,

i'm working on a small tool to convert some files. while the program is
running, the user is being asked to enter some file-paths.
i'm actually doing this with a cin, but it would be -...

hi,

i wrote a small function that expects a double and gives back
a char pointer with the value as char-string.
the first time i use it in my program it works fine, but if i call the
function a...

hi,

i do know about the difference of tmpnam and mkstemp, but because i need
to get a "free" name to open the filestream later by myself instead of the
mkstemp that already opens the stream and...
