glm::unpackUnorm2x8(...)

glm::vec2 glm::unpackUnorm2x8(glm::uint16 p)

Documentation from code comments


First, unpacks a single 16-bit unsigned integer p into a pair of 8-bit unsigned integers. Then, each component is converted to a normalized floating-point value to generate the returned two-component vector.

The conversion for unpacked fixed-point value f to floating point is done as follows: unpackUnorm4x8: f / 255.0

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.

glm::unpackUnorm3x10_1x2(...)

glm::vec4 glm::unpackUnorm3x10_1x2(glm::uint32 p)

Documentation from code comments


First, unpacks a single 32-bit unsigned integer p into four 16-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: unpackSnorm3x10_1x2(xyz): clamp(f / 1023.0, 0, +1) unpackSnorm3x10_1x2(w): clamp(f / 3.0, 0, +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.

glm::vec4 glm::unpackUnorm4x16(glm::uint64 p)

Documentation from code comments


First, unpacks a single 64-bit unsigned integer p into four 16-bit unsigned 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: unpackUnormx4x16: f / 65535.0

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.
