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.
