Detailed Description

Cache-friendly array of Quaternion represented as a SoA array.

Remarks

ArrayQuaternion is a SIMD & cache-friendly version of Quaternion. An operation on an ArrayQuaternion is done on 4 quaternions at a time (the actual amount is defined by ARRAY_PACKED_REALS) Assuming ARRAY_PACKED_REALS == 4, the memory layout will be as following: mChunkBase mChunkBase + 4 WWWW XXXX YYYY ZZZZ WWWW XXXX YYYY ZZZZ Extracting one quat (XYZW) needs 64 bytes, which is within the 64 byte size of common cache lines. Architectures where the cache line == 32 bytes may want to set ARRAY_PACKED_REALS = 2 depending on their needs

Cmov4() [1/6]

void Ogre::ArrayQuaternion::Cmov4 ( ArrayMaskR  mask, const ArrayQuaternion &  replacement  )

inline

Conditional move update.

Changes each of the four vectors contained in 'this' with the replacement provided:

this[i] = mask[i] != 0 ? this[i] : replacement[i]

See also

MathlibC::Cmov4

Remarks

If mask param contains anything other than 0's or 0xffffffff's the result is undefined. Use this version if you want to decide whether to keep current result or overwrite with a replacement (performance optimization). i.e. a = Cmov4( a, b ) If this vector hasn't been assigned yet any value and want to decide between two ArrayQuaternions, i.e. a = Cmov4( b, c ) then see Cmov4( const ArrayQuaternion &arg1, const ArrayQuaternion &arg2, ArrayMaskR mask ); instead.

Parameters

replacement	Vectors to be used as replacement if the mask is zero.
mask	mask filled with either 0's or 0xFFFFFFFF

Cmov4() [2/6]

void Ogre::ArrayQuaternion::Cmov4 ( ArrayMaskR  mask, const ArrayQuaternion &  replacement  )

mul() [1/3]

static void Ogre::ArrayQuaternion::mul ( const ArrayQuaternion &  inQ, ArrayVector3 &  inOutVec  )

inlinestatic

Rotates a vector by multiplying the quaternion to the vector, and modifies it's contents by storing the results there.

Remarks

This function is the same as doing: ArrayVector v; ArrayQuaternion q; v = q * v; In fact, the operator overloading will make above code work perfectly. However, because we don't trust all compilers in optimizing this performance-sensitive function (in fact MSVC 2008 doesn't inline the op. and generates an unnecessary ArrayVector3) this function will take the input vector, and store the results back on that vector. This is very common when concatenating transformations on an ArrayVector3, whose memory reside in the heap (it makes better usage of the memory). Long story short, prefer calling this function to using an operator when just updating an ArrayVector3 is involved. (It's fine using operators for ArrayVector3s)

mul() [2/3]

static void Ogre::ArrayQuaternion::mul ( const ArrayQuaternion &  inQ, ArrayVector3 &  inOutVec  )

Returns the Y orthonormal axis defining the quaternion.

Same as doing yAxis = Vector3::UNIT_Y * this. Also called the local Y-axis

zAxis() [1/3]

ArrayVector3 Ogre::ArrayQuaternion::zAxis ( ) const

inline

Returns the Z orthonormal axis defining the quaternion.

Same as doing zAxis = Vector3::UNIT_Z * this. Also called the local Z-axis

zAxis() [2/3]

ArrayVector3 Ogre::ArrayQuaternion::zAxis ( ) const

inline

Returns the Z orthonormal axis defining the quaternion.

Same as doing zAxis = Vector3::UNIT_Z * this. Also called the local Z-axis

zAxis() [3/3]

ArrayVector3 Ogre::ArrayQuaternion::zAxis ( ) const

inline

Returns the Z orthonormal axis defining the quaternion.

Same as doing zAxis = Vector3::UNIT_Z * this. Also called the local Z-axis
