Any
Check whether any element of a boolean vector is true
Declaration
bool all(bvec2 x)
bool all(bvec3 x)
bool all(bvec4 x)
Parameters
x
specifies the vector to be tested for truth.
Description
any()
returns true if any element of x
is true
and false
otherwise. It is functionally equivalent to:
bool any(bvec x) { // bvec can be bvec2, bvec3 or bvec4
bool result = false;
int i;
for (i = 0; i < x.length(); ++i) {
result |= x[i];
}
return result;
}
