process_transform_arguments

k3d.transform.process_transform_arguments(drawable, **kwargs)

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 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
