This function provides a single call that will make a set of modifications to an OmniGraph. It can be used to create a new graph from scratch or to make changes to an existing graph. If the "undoable" mode is not set to False then a single undo will revert everything done via this call. The description below contains different sections that perform different operations on the graph. They are always done in the order listed to minimize conflicts. If you need to execute them in a different order then use multiple calls to edit(). This function can be called either from the class or using an instantiated object. When callling from an object context the arguments passed in will take precedence over the arguments provided to the constructor. Here are some of the legal ways to call the edit function: .. code-block:: python # For example purposes "cmds()" is a function that returns a dictionary of editing commands (graph, _, _, _) = og.Controller.edit("/TestGraph", cmds()) new_controller = og.Controller(graph) new_controller.edit(cmds()) og.Controller.edit(graph, cmds()) new_controller.edit(graph, cmds()) new_controller.edit(graph, cmds(), undoable=False) # Overrides the normal undoable state of new_controller Below is the list of the allowed operations, in the order in which they will be performed. The parameters are described as lists, though if you have only one parameter for a given operation you can pass it without it being in a list. .. code-block:: python { OPERATION: [List, Of, Arguments] } { OPERATION: SingleArgument } For brevity the shortcut "keys = og.Controller.Keys" is assumed to exist. - keys.DELETE_NODES: NodeSpecs_t Deletes a node or list of nodes. If the node specification is a relative path then it must be in the list of full paths that the controller created in a previous call to edit(). { keys.DELETE_NODES: ["NodeInGraph", "/Some/Other/Graph/Node", my_omnigraph_node] } - keys.CREATE_NODES: [(Path_t, NodeType_t)] Constructs a node of the given type at the given path. If the path is a relative one then it is added directly under the graph being edited. A map is remembered between the given path, relative or absolute, and the node created at it so that further editing functions can refer to the node by that name directly rather than trying to infer the final full name. { keys.CREATE_NODES: [("NodeInGraph", "omni.graph.tutorial.SimpleData"), ("Inner/Node/Path", og.NodeType(node_type_name))] } - keys.CREATE_PRIMS: [(Path_t, {ATTR_NAME: (AttributeType_t, ATTR_VALUE)}, Optional(PRIM_TYPE))] Constructs a prim at path "PRIM_PATH" containing a set of attributes with specified types and values. Only those attribute types supported by USD can be used here, though the type specification can be in OGN form - invalid types result in an error. Whereas relative paths on nodes are treated as being relative to the graph, for prims a relative path is relative to the stage root. Prims are not allowed inside an OmniGraph and attempts to create one there will result in an error. Note that the PRIM_TYPE can appear with or without an attribute definition. (Many prim types are part of a schema and do not require explicit attributes to be added.) { keys.PRIMS: [("/World/Prim", {"speed": ("double", 1.0)}), ("/World/Cube", "Cube"), ("RootPrim", { "mass": (Type(BaseDataType.DOUBLE), 3.0), "force:gravity": ("double", 32.0) })]} - keys.CONNECT: [(AttributeSpec_t, AttributeSpec_t)] Makes a connection between the given source and destination attributes. The local name of a newly created node may be made as part of the node in the spec, or the node portion of the attribute path: { keys.CONNECT: [("NodeInGraph.outputs:value", ("inputs:value", "NodeInGraph"))]} - keys.DISCONNECT: [(AttributeSpec_t, AttributeSpec_t)] Breaks a connection between the given source and destination attributes. The local name of a newly created node may be made as part of the node in the spec, or the node portion of the attribute path: { keys.DISCONNECT: [("NodeInGraph.outputs:value", ("inputs:value", "NodeInGraph"))]} - keys.EXPOSE_PRIMS: [(cls.PrimExposureType, Prim_t, NewNode_t)] Exposes a prim to OmniGraph through creation of one of the node types designed to do that. The first member of the tuple is the method used to expose the prim. The prim path is the second member of the tuple and it must already exist in the USD stage. The third member of the tuple is a node name with the same restrictions as the name in the CREATE_NODES edit. { keys.EXPOSE_PRIMS: [(cls.PrimExposureType.AS_BUNDLE, "/World/Cube", "BundledCube")] } - keys.SET_VALUES: [AttributeSpec_t, Any] or [AttributeSpec_t, Any, AttributeType_t] Sets the value of the given list of attributes. { keys.SET_VALUES[("/World/Graph/Node.inputs:attr1", 1.0), (("inputs:attr2", node), 2.0)] } In the case of extended attribute types you may also need to supply a data type, which is the type the attribute will resolve to when the value is set. To supply a type, add it as a third parameter to the attribute value: { keys.SET_VALUES[("inputs:ext1", node), 2.0, "float"] } - keys.CREATE_VARIABLES: [(VariableName_t, VariableType_t)] Constructs a variable on the graph with the given name and type. The type can be specified as either a ogn type string (e.g. "float4"), or as an og.Type (e.g. og.Type(og.BaseDataType.FLOAT)) { keys.CREATE_VARIABLES[("velocity", "float3"), ("count", og.Type(og.BaseDataType.INT))] } Here's a simple call that first deletes an existing node "/World/PushGraph/OldNode", then creates two nodes of type "omni.graph.tutorials.SimpleData", connects their "a_int" attributes, disconnects their "a_float" attributes and sets the input "a_int" of the source node to the value 5. It also creates two unused USD Prim nodes, one with a float attribute named "attrFloat" with value 2.0, and the other with a boolean attribute named "attrBool" with the value true. .. code-block:: python controller = og.Controller() keys = og.Controller.Keys (graph, nodes_constructed, prims_constructed, path_to_object_map) = controller.edit("/World/PushGraph", { keys.DELETIONS: [ "OldNode" ], keys.CREATE_NODES: [ ("src", "omni.graph.tutorials.SimpleData"), ("dst", "omni.graph.tutorials.SimpleData") ], keys.CREATE_PRIMS: [ ("Prim1", {"attrFloat": ("float", 2.0)), ("Prim2", {"attrBool": ("bool", true)), ], keys.CONNECT: [ ("src.outputs:a_int", "dst.inputs:a_int") ], keys.DISCONNECT: [ ("src.outputs:a_float", "dst.inputs:a_float") ], keys.SET_VALUES: [ ("src.inputs:a_int", 5) ] keys.CREATE_VARIABLES: [ ("a_float_var", og.Type(og.BaseDataType.FLOAT)), ("a_bool_var", "bool") ] } ) .. note:: The controller object remembers where nodes are created so that you can use short forms for the node paths for convenience. That's why in the above graph the node paths for creation and the node specifications in the connections just says "src" and "dst". As they have no leading "/" they are treated as being relative to the graph path and will actually end up in "/World/PushGraph/src" and "/World/PushGraph/dst". Node specifications with a leading "/" are assumed to be absolute paths and must be inside the path of an existing or created graph. e.g. the NODES reference could have been "/World/PushGraph/src", however using "/src" would have been an error. This node path mapping is remembered across multiple calls to edit() so you can always use the shortform so long as you use the same Controller object. Args: obj: Either cls or self depending on how edit() was called graph_id: Identifier that says which graph is being edited. See :py:meth:`GraphController.create_graph` for the data types accepted for the graph description. edit_commands: Dictionary of commands and parameters indicating what modifications are to be made to the specified graph. A strict set of keys is accepted. Each of the values in the dictionary can be either a single value or a list of values of the proscribed type. path_to_object_map: Dictionary of relative paths mapped on to their full path after creation so that the edit_commands can use either full paths or short-forms to specify the nodes. update_usd: If specified then override whether to update the USD after the operations (default False) undoable: If True the operation is added to the undo queue, else it is done immediately and forgotten (default True) Returns: A 4-tuple consisting of: - the og.Graph being used for the operation - the list of og.Nodes created by the operation - the list of Usd.Prims created by the operation - the map of node/prim path name to the created og.Node/Usd.Prim objects.

"""Contains support for wrapping Python objects around FlatCache typed data These patterns draw heavily on the interfaces used by numpy as that is what is provided when dealing with Python data on the CPU. The intent is to make the data interface pattern as similar as possible to make dealing with it more consistent, though not to try to replicate any of the numpy functionality - that is left up to the interpreter of this data. The data wrapper consists of a raw memory pointer and a set of type identification information that corresponds to the types supported by FlatCache (including those that will be supported in the foreseeable future). One major way that the data typing differs from numpy is in the shape specification. While numpy insists that its data be a matrix (i.e. a shape of (2,3) means a fully populated 2x3 matrix) this shape specification can include different index counts in each level to accommodate gathered data. To avoid ambiguity the gathered element sizes are placed in a tuple, even when it's only a single value. e.g. 4x4 matrix = shape(4, 4) Array of 5 4x4 matrixes = shape(5, 4, 4) Two gathered 4x4 matrixes = shape((2,), 4, 4) Two gathered arrays of 5 and 6 4x4 matrixes = shape((5, 6), 4, 4) Here's how the shapes correspond to the access patterns, where the values returned are either memory pointers to a particular element or another DataWrapper which access the sub-array. The indexes in the shape are from largest scope to smallest scope, so gathered size is first, then array size, then tuple size. The index operator can be specified by one or more index values, traversing down multiple levels of the array hierarchy. These two are equivalent, though the first is more efficient - wrapper[I, J, K], wrapper[I][J][K] These are the shape types currently supported by FlatCache, using float values as examples: None - "Item is a single value, not an array" (2,) - "An array of two elements" float[] of size 2 index[I] is the Ith element of the array float[2] index[I] is the Ith tuple member ((2,)) - "A gathered set of two items" float with 2 gathered items index[I] is the Ith gathered item (2,3) - "An array of 2 arrays with 3 elements each" float[3][] of size 2 item[I] = Ith float[3] in the array item[I, J] = Jth tuple member of the Ith float[3] in the array ((2,),3) - "An array of two arrays with 3 elements each" float[3] with 2 gathered items item[I] = Ith gathered float[3] item[I, J] = Jth tuple member of the Ith gathered float[3] ((3,4)) - "An array of 2 arrays, the first with 3 elements, the second with 4" float[] with gathered items of sizes 3 and 4 item[I] = Ith gathered array of floats item[I, J] = Jth element of the Ith gathered float[] ((2,3),3) - "An array of 2 arrays of arrays with 3 elements, the first is an array of 2 arrays, the second is an array of 3 arrays" float[3][] with 2 gathered array items of length 2 and 3 respectively item[I] = Ith gathered array of float[3]s item[I, J] = Jth element of the Ith gathered array of float[3]s item[I, J, K] = Kth tuple member of the Jth element of the Ith gathered array of float[3]s There are also special cases for arrays, which are like tuples but have two index numbers for row and column.
