i have a problem with “vector”, error “cuse of class template vector requires template arguments” what can it be? what template argumnes and where i must write it?
i now that ther is in C++.

what is in your testApp? i think you get that error because it’s not defined as a type.
vector <ofVec2f> points
or
vector <ofPoint> points
but what exactly do you want to do?

I will try in this way:
//in testApp.h
vector < ofVec3f > points;
vector < ofColor > colors;
vector < int > indexs;
///update
vector <ofVec3f> temppoints;
vector < ofColor> tempcolors;
vector <int> tempindexs;

i’m tried this before, and i have this errors:

usually for me vector < ofVec3f> works fine for me in Ubuntu12.04 64bit. Try also to add a
///testApp.h
using namespace std;
and std::vector instead of only vector
but where do you receive that error exactly? at what line? because reading the code i have the suspect that what i suggest to you in the previous topic do nothing.

i’m took this code here (http://blog.rettuce.com/mediaart/kinect-of-delaunay/ ). the first code with point cloud work’s, with second how u see i have problems. but i need the working this code

i looked at the blog. i can’t understand anything, sorry. google translate is very bad in this case… but what i can say is that for me
vector < vector > points;
vector < vector > colors;
vector < vector > indexs;
this is wrong because you can make a vector of a vector but you must defined what type of vector.
vector <vector <ofVec3f>> points;
vector <vector<ofColor>> colors;
vector<vector<int>>indexs;
also i don’t know if the all the code is posted in the blog and if could be others relevant and important sections or errors like the above.
maybe you can also ask an advice to the author of the article in the blog…

happy that you solved! good luck with Openframeworks!
Hi Guys,
I am also trying to hack at that same piece of code… struggling to get it working.
Can somebody post the resolved piece of code?
Cheers!
hi @oliverellmers you can find that code in my github repo : https://github.com/kalwalt/OFexamples/tree/master/delaunayKinect .
