All

Check whether all elements of a boolean vector are true

Declaration

bool any(bvec2 x)  
bool any(bvec3 x)  
bool any(bvec4 x)

Parameters

x specifies the vector to be tested for truth.

Description

all() returns true if all elements of x are true and false otherwise. It is functionally equivalent to:

bool all(bvec x){       // bvec can be bvec2, bvec3 or bvec4
    bool result = true;
    int i;
    for (i = 0; i < x.length(); ++i)
    {
        result &= x[i];
    }
    return result;
}
