Spline3D

Class Spline3D()

Spline3D(parent='MODEL', name='DeformableCurve_n', label='DeformableCurve_n', 
active=True, type='FILE', extrap='NORMAL', csv_file='', xy_value=[0, 0, 0, 0, 0, 0, 0, 0, 0], 
z_value=[0, 0], y_scale=[1, 1], y_offset=[0, 0], x_scale=1, x_offset=0, 
z_scale=1, z_offset=0, is_file_valid=False)

A Spline3D is an extension of 2D curve and is a series of X:Y data for a finite set of Z values.

Keyword Arguments

Argument	Data Type	Description	Default
name	String	The variable name.	Spline3D_n, for next available integer n.
label	String	The descriptive label.	Spline3D_n, for next available integer n.
parent	Object	The parent.	MODEL
active	Boolean	Used to activate or deactivate this entity.	True
type	Enum	Indicates the usage of an external file or a set of values as input data. One of FILE or VALUE.	FILE
extrap	Enum	Determines if linear extrapolation should be used in the Y data. One of NORMAL or EXTRAP.	NORMAL
csv_file	File	The file path of the .csv file when the spline is defined with FILE as the type.	''
xy_value	NumericVector	Represents a list consisting of X column data and Y columns data created when the data is provided either through an external file (using the FILE type) or as values (using the VALUE type). List should be in the format: [x_value, y0_value, y1_value].	[0,0,0,0,0,0,0,0,0]
z_value	NumericVector	The list of Z values that corresponds to a set of Y column data.	[0,0]
y_scale	NumericVector	The scale value applied to the Y data.	[1.0,1.0]
y_offset	NumericVector	The offset value applied to the Y data.	[0,0]
x_scale	Double	The scale value applied to the X data.	1
x_offset	Double	The offset value applied to the X data.	0
z_scale	Double	The scale value applied to the Z data.	1
z_offset	Double	The offset value applied to the Z data.	0
is_file_valid	Boolean	Determines whether the format of the .csv file is valid or not.	False

Readonly Properties

Argument	Data Type	Description	Default
x	NumericVector	Returns the X column data of the spline. This array inherits the values from either the xy_value array (when the type is set to VALUE) or from the .csv file when the type is set to FILE) and factors in the x_scale and x_offset applied.	[0,0,0]
y	NumericVector	Returns the Y column data of the spline. This array inherits the values from either the xy_value array (when the type is set to VALUE) or from the .csv file when the type is set to FILE) and factors in the y_scale and y_offset applied.	[[0,0,0],[0,0,0]]
z	NumericVector	Returns the Z column data of the spline. This array inherits the values from either the z_value array (when the type is set to VALUE) or from the .csv file when the type is set to FILE) and factors in the z_scale and z_offset applied.	[0,0,0]

Examples

Create and modify attributes of a Spline3D.

   >>> # Import mview module
   >>> from hw import mview
   >>> spl = mview.Spline3D()
   >>> spl.type
   'FILE'
   >>> # Change the type to values
   >>> spl.type = 'VALUE'
   >>> spl.type
   'VALUE'
   >>> # Modify the x, y and z values
   >>> spl.z_value = [1,2,3]
   >>> spl.xy_value=[1,2,3,4,5,6,7,8,9,10,11,12]
   >>> # Change the z scale to 2
   >>> spl.z_scale = 2
