pymel.core.modeling.sphere¶

sphere(*args, **kwargs)¶

The sphere command creates a new sphere. The number of spans in the in each direction of the sphere is determined by the useTolerance attribute. If -ut is true then the -tolerance attribute will be used. If -ut is false then the -sections attribute will be used.

Flags:

Long Name / Short Name		Argument Types	Properties
axis / ax		float, float, float
	The primitive’s axis
caching / cch		bool
	Toggle caching for all attributes so that no recomputation is needed
constructionHistory / ch		bool
	Turn the construction history on or off.
degree / d		int
	The degree of the resulting surface: 1 - linear, 3 - cubic Default:3
endSweep / esw		float
	The angle at which to end the surface of revolution. Default is 2Pi radians, or 360 degrees. Default:6.2831853
frozen / fzn		bool
heightRatio / hr		float
	Ratio of heightto widthDefault:2.0
name / n		unicode
	Sets the name of the newly-created node. If it contains namespace path, the new node will be created under the specified namespace; if the namespace does not exist, it will be created.
nodeState / nds		int
	Maya dependency nodes have 6 possible states. The Normal (0), HasNoEffect (1), and Blocking (2)states can be used to alter how the graph is evaluated. The Waiting-Normal (3), Waiting-HasNoEffect (4), Waiting-Blocking (5)are for internal use only. They temporarily shut off parts of the graph during interaction (e.g., manipulation). The understanding is that once the operation is done, the state will be reset appropriately, e.g. Waiting-Blockingwill reset back to Blocking. The Normaland Blockingcases apply to all nodes, while HasNoEffectis node specific; many nodes do not support this option. Plug-ins store state in the MPxNode::stateattribute. Anyone can set it or check this attribute. Additional details about each of these 3 states follow. StateDescriptionNormalThe normal node state. This is the default.HasNoEffectThe HasNoEffectoption (a.k.a. pass-through), is used in cases where there is an operation on an input producing an output of the same data type. Nearly all deformers support this state, as do a few other nodes. As stated earlier, it is not supported by all nodes. Its typical to implement support for the HasNoEffectstate in the nodes compute method and to perform appropriate operations. Plug-ins can also support HasNoEffect. The usual implementation of this state is to copy the input directly to the matching output without applying the algorithm in the node. For deformers, applying this state leaves the input geometry undeformed on the output. BlockingThis is implemented in the depend node base class and applies to all nodes. Blockingis applied during the evaluation phase to connections. An evaluation request to a blocked connection will return as failures, causing the destination plug to retain its current value. Dirty propagation is indirectly affected by this state since blocked connections are never cleaned. When a node is set to Blockingthe behavior is supposed to be the same as if all outgoing connections were broken. As long as nobody requests evaluation of the blocked node directly it wont evaluate after that. Note that a blocked node will still respond to getAttrrequests but a getAttron a downstream node will not reevaluate the blocked node. Setting the root transform of a hierarchy to Blockingwont automatically influence child transforms in the hierarchy. To do this, youd need to explicitly set all child nodes to the Blockingstate. For example, to set all child transforms to Blocking, you could use the following script. import maya.cmds as cmds def blockTree(root): nodesToBlock = [] for node in {child:1 for child in cmds.listRelatives( root, path=True, allDescendents=True )}.keys(): nodesToBlock += cmds.listConnections(node, source=True, destination=True ) for node in {source:1 for source in nodesToBlock}.keys(): cmds.setAttr( ‘%s.nodeState’ % node, 2 ) Applying this script would continue to draw objects but things would not be animated. Default:kdnNormal
object / o		bool
	Create the result, or just the dependency node.
pivot / p		float, float, float
	The primitive’s pivot point
polygon / po		int
	The value of this argument controls the type of the object created by this operation 0: nurbs surface1: polygon (use nurbsToPolygonsPref to set the parameters for the conversion)2: subdivision surface (use nurbsToSubdivPref to set the parameters for the conversion)3: Bezier surface4: subdivision surface solid (use nurbsToSubdivPref to set the parameters for the conversion)Flag can have multiple arguments, passed either as a tuple or a list.
radius / r		float
	The radius of the object Default:1.0
sections / s		int
	The number of sections determines the resolution of the surface in the sweep direction. Used only if useTolerance is false. Default:8
spans / nsp		int
	The number of spans determines the resolution of the surface in the opposite direction. Default:1
startSweep / ssw		float
	The angle at which to start the surface of revolution Default:0
tolerance / tol		float
	The tolerance with which to build the surface. Used only if useTolerance is true Default:0.01
useTolerance / ut		bool
	Use the specified tolerance to determine resolution. Otherwise number of sections will be used. Default:false Common flags

Derived from mel command maya.cmds.sphere

Example:

import pymel.core as pm

# Create sphere with radius 10
pm.sphere( r=10 )
# Result: [nt.Transform(u'nurbsSphere1'), nt.MakeNurbSphere(u'makeNurbSphere1')] #

# Query the radius of the new sphere
r = pm.sphere( 'nurbsSphere1', q=True, r=True )

# Create half sphere
pm.sphere( ssw=0, esw=180 )
# Result: [nt.Transform(u'nurbsSphere2'), nt.MakeNurbSphere(u'makeNurbSphere2')] #

# Use tolerance to determine how many spans the new sphere has
pm.sphere( ut=True, tol=0.01 )
# Result: [nt.Transform(u'nurbsSphere3'), nt.MakeNurbSphere(u'makeNurbSphere3')] #

# Use sections to determine how many spans the new sphere has
pm.sphere( ut=False, s=8 )
# Result: [nt.Transform(u'nurbsSphere4'), nt.MakeNurbSphere(u'makeNurbSphere4')] #
