Chapter 17 Picking - multy renderItem picking fail

[RKGekk]

if vector mRitemLayer contain more than one renderItem then rayOrigin and rayDir are overwrite with wrong values.

XMMATRIX W = XMLoadFloat4x4(&ri->World);
XMMATRIX invWorld = XMMatrixInverse(&XMMatrixDeterminant(W), W);
XMMATRIX toLocal = XMMatrixMultiply(invView, invWorld);
//multiple times overwrite
rayOrigin = XMVector3TransformCoord(rayOrigin, toLocal);
rayDir = XMVector3TransformNormal(rayDir, toLocal);
rayDir = XMVector3Normalize(rayDir);

fixed version:
XMMATRIX W = XMLoadFloat4x4(&ri->World);
XMMATRIX invWorld = XMMatrixInverse(&XMMatrixDeterminant(W), W);
XMMATRIX toLocal = XMMatrixMultiply(invView, invWorld);
XMVECTOR rayOriginLoc = XMVector3TransformCoord(rayOrigin, toLocal);
XMVECTOR rayDirLoc = XMVector3TransformNormal(rayDir, toLocal);
rayDirLoc = XMVector3Normalize(rayDirLoc);
