// Aligned Matrices
|

//
|
|
// This class helps keep matrices 16-byte aligned as preferred by P4 cpus.
|
|
// It aligns matrices on the stack and on the heap or in global scope.
|
|
// It does this using __declspec(align(16)) which works on VC7 and on VC 6
|
|
// with the processor pack. Unfortunately there is no way to detect the
|
|
// latter so this is turned on only on VC7. On other compilers this is the
|
|
// the same as D3DXMATRIX.
|
|
// Using this class on a compiler that does not actually do the alignment
|
|
// can be dangerous since it will not expose bugs that ignore alignment.
|
|
// E.g if an object of this class in inside a struct or class, and some code
|
|
// memcopys data in it assuming tight packing. This could break on a compiler
|
|
// that eventually start aligning the matrix.
