# process_transform_arguments#

k3d.transform.process_transform_arguments(drawable, **kwargs)[source]#

Create a Transform to apply to a drawable.

Parameters
• drawable (object) – Drawable object.

• **kwargs

transformTransform

Existing Trasnform to be (re-)used on the drawable.

xminfloat

Lower bound in x dimsension.

xmaxfloat

Upper bound in x dimsension.

yminfloat

Lower bound in y dimsension.

ymaxfloat

Upper bound in y dimsension.

zminfloat

Lower bound in z dimsension.

zmaxfloat

Upper bound in z dimsension.

bounds: array_like

Dimensions bounds taking precedence over seperate bound arguments, [xmin, xmax, ymin, ymax, zmin, zmax] or [xmin, xmax, ymin, ymax].

translationarray_like

[tx, ty, tz] translation vector.

rotationarray_like

[gamme, rx, ry, rz] rotation vector (radians).

scalingarray_like

[sx, sy, sz] scaling coefficients.

model_matrixndarray

Matrix of numbers. Must have four columns.

Returns

Transformed Drawable.

Return type

Drawable

Raises

ValueError – Provided transform argument is not a Transform object.

## Examples#

```import k3d
import numpy as np
from k3d.transform import process_transform_arguments

vertices = [[1, 1, 1], [1, -1, -1], [-1, 1, -1], [-1, -1, 1]]
indices = [[0, 1, 2], [0, 2, 3], [0, 3, 4], [0, 3, 1], [3, 2, 1]]

plt_tetra = k3d.mesh(vertices, indices,
color=0x00a86b)
plt_tetra1 = k3d.mesh(vertices, indices,
color=0x4ca5ff)

process_transform_arguments(plt_tetra1,
translation=[1, 3, 0],
rotation=[1, np.pi / 2, 0, 0],
scaling=[0.5, 1, 1.5])

plot = k3d.plot()
plot += plt_tetra
plot += plt_tetra1
plot.display()
