apply.transform {fsbrain} | R Documentation |
Apply matmult transformation to input.
Description
Apply affine transformation, like a *vox2ras_tkr* transformation, to input. This is just matrix multiplication for different input objects.
Usage
apply.transform(object, matrix_fun)
Arguments
object |
numerical vector/matrix or Triangles3D instance, the coorindates or object to transform. |
matrix_fun |
a 4x4 affine matrix or a function returning such a matrix. If 'NULL', the input is returned as-is. In many cases you way want to use a matrix computed from the header of a volume file, e.g., the 'vox2ras' matrix of the respective volume. See the 'mghheader.*' functions in the *freesurferformats* package to obtain these matrices. |
Value
the input after application of the affine matrix (matrix multiplication)
