when i run scene reconstruction example it gives wrong set of points when i checked my openCL comparability i found that my laptop doesnt support openCL, could this be the problem for the wrong 3d points ?

edit

you could try to toggle opencl usage at runtime, and see:

#include "opencv2/core/ocl.h"

int main() {
    ocl::setUseOpenCL(false);
    ...

i did so but nothing happened !! what should have happened to tell me if iam right or wrong
