Noticed mikktspace.c defines its own math functions:
typedef struct
{
float x, y, z;
} SVec3;
tbool veq( const SVec3 v1, const SVec3 v2 )
onst SVec3 vadd( const SVec3 v1, const SVec3 v2 )
const SVec3 vsub( const SVec3 v1, const SVec3 v2 )
const SVec3 vscale(const float fS, const SVec3 v)
float LengthSquared( const SVec3 v )
float Length( const SVec3 v )
const SVec3 Normalize( const SVec3 v )
const float vdot( const SVec3 v1, const SVec3 v2)
tbool NotZero(const float fX)
tbool VNotZero(const SVec3 v)
With external libs like fluid-sim or bullet, defining own types is
un-avoidable but for blenlib or blenkernel functions I prefer we stick
to BLI_math.h defined functions.
