pymel.core.modeling.polyPrism¶
- polyPrism(*args, **kwargs)¶
The prism command creates a new polygonal prism.
Flags:
Long Name / Short Name Argument Types Properties axis / ax float, float, float This flag specifies the primitive axis used to build the prism. Q: When queried, this flag returns a float[3]. caching / cch bool Toggle caching for all attributes so that no recomputation is needed constructionHistory / ch bool Turn the construction history on or off (where applicable). If construction history is on then the corresponding node will be inserted into the history chain for the mesh. If construction history is off then the operation will be performed directly on the object. Note:If the object already has construction history then this flag is ignored and the node will always be inserted into the history chain. createUVs / cuv int This flag alows a specific UV mechanism to be selected, while creating the primitive. The valid values are 0, 1, 2 or 3. 0 implies that no UVs will be generated (No texture to be applied). 1 implies UVs should be created for the object as a whole without any normalization. The primitive will be unwrapped and then the texture will be applied without any distortion. In the unwrapped primitive, the shared edges will have shared UVs. 2 implies the UVs should be normalized. This will normalize the U and V direction separately, thereby resulting in distortion of textures. 3 implies UVs are created so that the texture will not be distorted when applied. The texture lying outside the UV range will be truncated (since that cannot be squeezed in, without distorting the texture. For better understanding of these options, you may have to open the texture view windowC: Default is 2. frozen / fzn bool length / l float This flag specifies the length of the prism. C: Default is 2.0. Q: When queried, this flag returns a float. 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 numberOfSides / ns int This specifies the number of sides for the prism. C: Default is 3. Q: When queried, this flag returns an int. numderOfSides / nsi int This specifies the number of sides for the prism. C: Default is 3. Q: When queried, this flag returns an int. object / o bool Create the result, or just the dependency node (where applicable). sideLength / w float This flag specifies the edge length of the prism. C: Default is 2.0. Q: When queried, this flag returns a float. subdivisionsCaps / sc int This flag specifies the subdivisions on the caps for the prism. C: Default is 2. Q: When queried, this flag returns an int. subdivisionsHeight / sh int This specifies the subdivisions along the height for the prism. C: Default is 1. Q: When queried, this flag returns an int. texture / tx int This flag is obsolete and will be removed in the next release. The -cuv/createUVs flag should be used instead. Flag can have multiple arguments, passed either as a tuple or a list. Derived from mel command maya.cmds.polyPrism
Example:
import pymel.core as pm # Create a prism, with 10 subdivisions on the caps, # and 15 subdivisions along the length, # the edge length of the prism is 20. pm.polyPrism ( sc=10, sh=15, w=20) # Create a prism, called "myprism", on each direction there are 5 subdivisions. pm.polyPrism( n='myprism', sc=5, sh=5)
