## Any
|
||
|
|
Check whether any element of a boolean vector is true
|
||
|
|
|
||
|
|
### Declaration
|
||
|
|
```glsl
|
||
|
|
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:
|
||
|
|
|
||
|
|
```glsl
|
||
|
|
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;
|
||
|
|
}
|
||
|
|
```
|
||
|
|
|
||
|
