Function glm::builtin::unpackSnorm4x8
[−]
[src]
pub fn unpackSnorm4x8(p: u32) -> Vec4
First, unpacks a single 32-bit unsigned integer p into four 8-bit signed
integers. Then, each component is converted to a normalized floating-point
value to generate the returned four-component vector.
The conversion for unpacked fixed-point value f to floating point is
done as follows: clamp(f / 127.0, -1, +1)
The first component of the returned vector will be extracted from the least significant bits of the input; the last component will be extracted from the most significant bits.
