SbMatrixMultDirMatrix Method (SbVec3f, SbVec3f)
Pre-multiplies matrix by given row vector, giving vector result.

Namespace: OIV.Inventor
Assembly: OIV.Inventor.SbLinear (in OIV.Inventor.SbLinear.dll) Version: 9.9.36.0.Release.d5e5954f18f5fba1171104a1eb3d2f8b0fc0d084
Syntax
public void MultDirMatrix(
	SbVec3f src,
	out SbVec3f dst
)

Parameters

src
Type: OIV.InventorSbVec3f
Source vector.
dst
Type: OIV.InventorSbVec3f
Output parameter for result.
Remarks
src is assumed to be a direction vector, so translation part of matrix is ignored.

Note that if you wish to transform surface points and normals by a matrix, call MultVecMatrix(SbVec3f, SbVec3f) for the points and call MultDirMatrix(SbVec3f, SbVec3f) on the inverse transpose of the matrix for the normals.

It is safe to let src and dst be the same object.
