Hi, guys.
Maybe I’m doing something wrong or maybe there’s a bug.
I have my own matrix (which is column-major) and there’s also yours - KFbxMatrix.
The following code doesn’t work for translation (everything is OK except translation, it’s zero):
KFbxMatrix mat = pNode->GetGlobalFromCurrentTake(pTime)
Matrix34 myMat;
for (unsigned int row = 0; row < 3; ++row)
{
for (unsigned int col = 0; col < 4; ++col)
{
myMat(row, col) = mat.Get(row, col)
}
}
Then I found the workaround. The following did work:
KFbxMatrix mat = pNode->GetGlobalFromCurrentTake(pTime)
Matrix34 myMat;
for (unsigned int row = 0; row < 3; ++row)
{
for (unsigned int col = 0; col < 4; ++col)
{
myMat(row, col) = ((double*)mat)[row + col * 4];
}
}
Is something wrong with matrix? ...
Regards,
Alexander.

Hi,JustPC,
The column-major in FBX means the last row of the matrix represents the translation part of the transformation.
So translation elements are mat.Get(3,0), mat.Get(3,1) and mat.Get(3,2).
