Polyline: ENS_POLYLINE

Methods:

• foo.createpolyline([description=s]): only available on the default polyline objst (ensight.objs.core.DEFAULTPOLYLINE[0]). It creates a new polyline, returning the created polyline.
• foo.destroy(): available on all but the default polyline. It destroys the polyline object (’foo’ in this example).
• foo.interpolate(list|scalar[,normal=1]): computes output x,y,z values interpolated along the polyline (as a spline) at the point or points specified by the list or scalar value. Note, all values should be in the range 0.0-1.0. By default, x,y,z are returned for each input value. If normal=1 is specified, the normal value is also returned for 6 floats at each evaluated point.

Attributes:

• SELECTED: is the object selected
• ID: the id of the polyline (used to refer to it from command language)
• VISIBLE: is the object visible at all
• POINTVISIBLE: are the control points visible
• POINTSIZE: size of the control points for display
• COLOR: color of the polyline
• DESCRIPTION: the name of the polyline
• LINEWIDTH: the width of the line for display
• NUMCONTROLPOINTS: the current number of control points
• CONTROLPOINTS: a list of 3 value lists containing the x,y,z values at each of the control points. Note: this attribute is read/write, allowing for a more efficient method of changing the control points.
