Detailed Description

Allow to perform bit operations on integer values.

Build a mask of 'count' bits From GLM_GTX_bit extension.

<glm/gtx/bit.hpp> need to be included to use these functionalities.


Function Documentation

genType glm::gtx::bit::bitRevert ( genType const &  value)

Revert all bits of any integer based type.

From GLM_GTX_bit extension.

genType glm::gtx::bit::bitRotateLeft ( genType const &  In,
std::size_t  Shift 
)

Rotate all bits to the left.

From GLM_GTX_bit extension.

genType glm::gtx::bit::bitRotateRight ( genType const &  In,
std::size_t  Shift 
)

Rotate all bits to the right.

From GLM_GTX_bit extension.

genIUType glm::gtx::bit::extractField ( genIUType const &  v,
sizeType const &  first,
sizeType const &  count 
)

Component wise extraction of bit fields.

genType and genIType could be a scalar or a vector. From GLM_GTX_bit extension.

int glm::gtx::bit::highestBit ( genType const &  value)

Find the highest bit set to 1 in a integer variable.

From GLM_GTX_bit extension.

genType glm::gtx::bit::highestBitValue ( genType const &  value)

Find the highest bit set to 1 in a integer variable and return its value.

From GLM_GTX_bit extension.

bool glm::gtx::bit::isPowerOfTwo ( genType const &  value)

Return true if the value is a power of two number.

From GLM_GTX_bit extension.

int glm::gtx::bit::lowestBit ( genType const &  value)

Find the lowest bit set to 1 in a integer variable.

From GLM_GTX_bit extension.

genType glm::gtx::bit::powerOfTwoAbove ( genType const &  value)

Return the power of two number which value is just higher the input value.

From GLM_GTX_bit extension.

genType glm::gtx::bit::powerOfTwoBelow ( genType const &  value)

Return the power of two number which value is just lower the input value.

From GLM_GTX_bit extension.

genType glm::gtx::bit::powerOfTwoNearest ( genType const &  value)

Return the power of two number which value is the closet to the input value.

From GLM_GTX_bit extension.
