Mixed transform allows to express common integer view transformations such as translation, rotation, rotoinversion, and projection.

It transform a n-dimensional source vector to a m-dimensional target vector, and can be represented as a m+1 × n+1 homogeneous matrix. The mixed transform can be decomposed as follows:

1. project down (discard some components of the source vector)
2. component permutation
3. component inversion
4. project up (add zero components in the target vector)
5. translation

Method Detail

getTranslation

void getTranslation(long[] translation)

Get the translation. Translation is added to the target vector after applying permutation, projection, inversion operations.

Parameters:

translation - array of size at least the target dimension to store the result.

getTranslation

long getTranslation(int d)

Get the d-th component of translation (see getTranslation(long[])).

Parameters:

d -

getComponentZero

void getComponentZero(boolean[] zero)

Get a boolean array indicating which target dimensions are _not_ taken from source dimensions.

For instance, if the transform maps 2D (x,y) coordinates to the first two components of a 3D (x,y,z) coordinate, the result will be [false, false, true]

Parameters:

zero - array of size at least the target dimension to store the result.

getComponentZero

boolean getComponentZero(int d)

Get the d-th component of zeroing vector (see getComponentZero(boolean[])).

Parameters:

d -

getComponentMapping

void getComponentMapping(int[] component)

Get an array indicating for each target dimensions from which source dimension it is taken.

For instance, if the transform maps 2D (x,y) coordinates to the first two components of a 3D (x,y,z) coordinate, the result will be [0, 1, x]. Here, the value of x is undefined because the third target dimension does not correspond to any source dimension. See getComponentZero(boolean[]).

Parameters:

component - array of size at least the target dimension to store the result.

getComponentMapping

int getComponentMapping(int d)

Get the source dimension which is mapped to the d-th target dimension (see getComponentMapping(int[])).

Parameters:

d -

getComponentInversion

void getComponentInversion(boolean[] invert)

Get an array indicating for each target component, whether the source component it is taken from should be inverted.

For instance, if rotating a 2D (x,y) coordinates by 180 degrees will map it to (-x,-y). In this case, the result will be [true, true].

Parameters:

invert - array of size at least the target dimension to store the result.

getComponentInversion

boolean getComponentInversion(int d)

Get the d-th component of inversion vector (see getComponentInversion(boolean[])).

Parameters:

d -

getMatrix

double[][] getMatrix()

Get the matrix that transforms homogeneous source points to homogeneous target points. For testing purposes.
