Method Details

addMetaelem(paramslist)

Add a new metaelem to this metaball. 'paramslist' must have the following ten elements:

param 1: int - metaelem type:
- 0 for a sphere
- 1 for a tubex
- 2 for a tubey
- 3 for a tubez
- 4 for a regular tube
- 5 for a plane
- 6 for an ellipsoid
- 7 for a cube
params 2,3,4: floats - the x, y and z coordinates of the metaelem.
param 5: float - the rad value of the metaelem.
param 6: int - the lay value.
param 7: float - the s value of the metaelem.
params 8,9,10: floats - the expx, expy and expz values of the metaelem.

Parameters:: paramslist - the list of the parameters for creating a new metaelem.
(type=list)

Returns:: None
(type=None)

getBbox()

Retrieves the bounding box of a metaball object.

Returns:: the bounding box of a metaball object
(type=a list of 24 floats(8 points, 3 coordinates))

getLoc()

Retrieves the location of a metaball object.

Returns:: location of a metaball object
(type=a list of 3 floats)

getMetadata(name, num)

Retrieves the metadata of a metaball object. A metaball is composed of one or several elementary objects, spheres or cylinders, which interact to create the smooth surface everybody knows. The get/set Metadata functions allow users to read/write the parameters of these elementary objects, called metaelements.

Parameters:: name - the name of the property to be read. The accepted values are :"type", "x", "y", "z", "expx", "expy", "expz", "rad", "rad2", "s", "len".
(type=string); num - the position of the metaelem to be accessed.
(type=int)

Returns:: the metaelement parameter value, generally a float, except for the parameter "type", which returns an int.
(type=float)

getMetaElemList()

retreives the list of the Metaelems of the Metaball

Returns:

List of Metaelem classes Each Metaelem object has NO function, but 4 read/write fields

coords : a list of three floats, the coordinates of the Metaelem object

dims : a list of three floats, the dimensions of the meteelem object

rad : a float, the radius of the object

stif : a float, the stifness of the object

Example :

import Blender

mb = Blender.Metaball.Get("mball")

ob = Blender.Object.Get("ob")

ll = mb.getMetaElemList()

me = ll[0]

old = me.coords

new = [old[0],old[1],old[2]-.02]

me.coords = new

ob.makeDisplayList()
