# filters.transformation¶

The transformation filter applies an arbitrary rotation+translation transformation, represented as a 4x4 matrix, to each xyz triplet.

The filter does no checking to ensure the matrix is a valid affine transformation.

Note

The transformation filter does not apply or consider any spatial reference information.

Default Embedded Stage

This stage is enabled by default

Streamable Stage

This stage supports streaming operations

## Example¶

This example rotates the points around the z-axis while translating them.

[
"untransformed.las",
{
"type":"filters.transformation",
"matrix":"0 -1  0  1  1  0  0  2  0  0  1  3  0  0  0  1"
},
{
"type":"writers.las",
"filename":"transformed.las"
}
]


## Options¶

matrix
A whitespace-delimited transformation matrix. The matrix is assumed to be presented in row-major order. Only matrices with sixteen elements are allowed.
