Detailed Description
This is the main engine behind all simulations. Any number of these can be created to create independent simulations. Generally a simulation will be owned by a particular OP_Node. For example, the DopNet object contains a SIM_Engine.- Examples:
-
SIM/SIM_GasAdd.C, SIM/SIM_GasAdd.h, SIM/SIM_SolverHair.C, SIM/SIM_SolverHair.h, SIM/SNOW_Solver.C, and SIM/SNOW_Solver.h.

| virtual SIM_Engine::~SIM_Engine | ( | ) | [virtual] |
Destructor to destroy all data associated with a simulation.
Member Function Documentation
| void SIM_Engine::addError | ( | const SIM_RootData * | rootdata, | |
| const SIM_Data * | data, | |||
| int | errorcode, | |||
| const char * | errorparm, | |||
| UT_ErrorSeverity | severity | |||
| ) | const |
Adds an error to the engine. The object and data parameters allow the DOP_Engine to put the error message on an appropriate DOP Node. Errors are found in the SIM error file. This function simply calls addErrorSubclass().
| virtual void SIM_Engine::addErrorSubclass | ( | const SIM_RootData * | rootdata, | |
| const SIM_Data * | data, | |||
| int | errorcode, | |||
| const char * | errorparm, | |||
| UT_ErrorSeverity | severity | |||
| ) | const [protected, virtual] |
| void SIM_Engine::addOPInterest | ( | OP_Node * | node | ) | const |
Adds an interest in the supplied node. When the node changes, the engine's handleExternalNodeChange function will be called.
| SIM_Relationship* SIM_Engine::addRelationship | ( | const char * | name, | |
| int | creationflags | |||
| ) |
Creates a new relationship. The creationflags parameter accepts the same SIM_DATA_* flags accepted by the creationflags parameter of SIM_Data::createNamedSubData().
- Examples:
- DOP/DOP_GroupAndApply.C.
| SIM_Object* SIM_Engine::addSimulationObject | ( | bool | solvefirstframe | ) |
Allocates a new SIM_Object and adds it to the simulation. The name parameter is assigned to the object. This name does not have to be unique.
| virtual void SIM_Engine::clearReferencesToMostRecentState | ( | ) | [protected, virtual] |
This function is called by our cache whenever the most recent simulated timestep is being removed from memory (either deleted or moved onto disk).
Reimplemented in DOP_Engine.
| void SIM_Engine::clearSelection | ( | ) | const |
Clears the selection flag on all data in this simulation.
| SIM_Object* SIM_Engine::createSubStepObject | ( | const SIM_Object & | object, | |
| const SIM_Time & | time | |||
| ) |
Creates an object in the current state with a particular time stamp. This function is useful for solvers that need to do their own time stepping with step sizes smaller than the globally specified time step size. These explicitly stored subsamples are accessible later with the getObjectAtTime() function.
| void SIM_Engine::filterConstRelationships | ( | const SIM_DataFilter & | filter, | |
| SIM_ConstDataArray & | rels | |||
| ) | const |
Gets all the relationships of a particular type. The type of a relationship is defined by the one subdata on the SIM_Relationship.
| void SIM_Engine::findAllObjectsCreatedBy | ( | OP_Node * | creator, | |
| SIM_ConstObjectArray & | objects | |||
| ) | const |
Returns a list of objects created by the specified node, or any nodes inside the specified node (if it is a subnet).
| void SIM_Engine::findAllObjectsFromString | ( | const char * | objspec, | |
| SIM_ConstObjectArray & | objects, | |||
| const SIM_Time & | t, | |||
| bool | interpolateobj | |||
| ) | const |
Filters all our simulation objects based on a string pattern. Note that the time value is a simulation time, not global time.
| void SIM_Engine::findAllRelationshipsFromString | ( | const char * | relspec, | |
| SIM_ConstDataArray & | relationships, | |||
| const SIM_Time & | t, | |||
| bool | interpolaterel | |||
| ) | const |
Filters all our relationships based on a string pattern. Note that the time value is a simulation time, not global time.
| const SIM_Object* SIM_Engine::findObjectFromString | ( | const char * | objspec, | |
| int | whichmatch, | |||
| int * | nummatch, | |||
| const SIM_Time & | t, | |||
| bool | interpolateobj | |||
| ) | const |
Returns a single object matching a specified string pattern. Note that the time value is a simulation time, not global time.
| const SIM_Relationship* SIM_Engine::findRelationshipFromString | ( | const char * | relspec, | |
| int | whichmatch, | |||
| int * | nummatch, | |||
| const SIM_Time & | t, | |||
| bool | interpolaterel | |||
| ) | const |
Returns a single relationship matching a specified string pattern. Note that the time value is a simulation time, not global time.
| SIM_Object* SIM_Engine::getAffectorAtTime | ( | SIM_Object & | object, | |
| const SIM_Time & | time, | |||
| bool | allowinterpolation | |||
| ) |
Returns a non-const pointer to an object for a particular time. This function is very similar to getObjectAtTime() except for two things. First, it requires a non-const starting object, and it is a non-const function. Second, if the specified time exactly matches a time in the past, the returned object will be a copy of that past object, not the object itself. Otherwise modifying that object could modify the past. However, if the current time is sepcified, the actual object (i.e. a pointer to the passed in SIM_Object) is returned. This function is for use by solvers that want to modify their affector objects and which do substepping.
| const SIM_CacheOptions& SIM_Engine::getCacheOptions | ( | ) | const |
Returns a reference to the cache options for this simulation.
Returns the SIM_Data pointer with the specified unique id.
| int SIM_Engine::getCurrentCreatorId | ( | ) | const |
Gets the id for the node that is currently being processed.
| int SIM_Engine::getCurrentCreatorIndex | ( | ) | const |
Gets the index of the node output that is currently being processed.
| void SIM_Engine::getDataTypes | ( | UT_StringArray & | datatypes, | |
| const char * | datatype | |||
| ) | const |
Returns all available data type names. If a null type pointer is passed in, this function returns a list of every data type that the SIM_Engine can create. If a data type name is passed in, the list returned will only contain those data types that can be cast to the specified data type using the SIM_Data::getPointerToType() function.
| void SIM_Engine::getDataTypeSources | ( | UT_StringArray & | datatypes, | |
| UT_StringArray & | srcs | |||
| ) | const |
Returns all available data types and the source of their definition. The definition source will be an empty string if the data type is defined internally to Houdini. Otherwise it will be the name of the DSO or DLL file that contains the data type.
| const char* SIM_Engine::getDescription | ( | const char * | datatype | ) | const |
Returns the descriptive name for a data type. Given the unique identifying name for a data type this function finds the appropriate data factory and returns the descriptive string assigned to the type.
| const SIM_DopDescription* SIM_Engine::getDopDescription | ( | const char * | datatype | ) | const |
Returns the SIM_DopDescription from the SIM_DataFactory of a particular data type.
| const SIM_Time& SIM_Engine::getEarliestCacheTime | ( | ) | const |
Returns the time of the earliest simulation state in the cache.
Returns the simulation time that corresponds to the given global time.
| int SIM_Engine::getFeedbackIteration | ( | ) | const |
Gets the current feedback iteration we are on. If we are not currently solving, this function will return -1;
Returns the global time that corresponds to the given simulation time.
| int SIM_Engine::getMaxFeedbackIterations | ( | ) | const |
Gets the maximum number of allowed feedback iterations.
| SIM_Object* SIM_Engine::getNonConstSimulationObject | ( | int | index | ) | [protected] |
This function is the only way for a SIM_Engine subclass to get a non-const SIM_Object pointer.
| const SIM_Object* SIM_Engine::getNthSimulationObject | ( | const SIM_DataFilter & | filter, | |
| int | n | |||
| ) | const |
Returns the "nth" simulation object that matches a supplied filter. If less than the supplied n objects match the filter, 0 is returned.
| int SIM_Engine::getNumRelationships | ( | ) | const |
Returns the number of relationships in the current simulation state.
| int SIM_Engine::getNumSimulationObjects | ( | ) | const |
Returns the number of objects currently in the simulation.
| const SIM_Object* SIM_Engine::getObjectAtTime | ( | const SIM_Object & | object, | |
| const SIM_Time & | time, | |||
| bool | allowinterpolation | |||
| ) | const |
Returns a pointer to the state of an object at some time in the past. This function searches for these past object states in three ways. First, if the specified time is equal to a past time step, the state for that time step is returned. Second, if the specified time is not equal to a past time step, then past time steps are searched for object states stored explicitly with createSubStepObject(). Finally, if both these methods fail to find a matching object state, then the closest object states before and after the specified time are found using the first two approaches. Then a new object state is created by interpolating between these two states using SIM_Data::interpolate(). This third approach is skipped if allowinterpolation is set to false. If no previous or no future object state can be found, then this function returns null.
| OP_Node* SIM_Engine::getOwner | ( | ) | const |
Returns the OP_Node that owns this engine. This may be null if the engine isn't associated with a particular node.
| const UT_String& SIM_Engine::getOwnerFullPath | ( | ) | const |
Gets the full path to the DOP Network node that owns this simulation.
| bool SIM_Engine::getProvideDataHints | ( | ) | const |
Returns true if the engine is providing data hierarchy hints.
| const SIM_Relationship* SIM_Engine::getRelationship | ( | const char * | name | ) | const |
Returns the relationship with the specified name.
| const SIM_Relationship* SIM_Engine::getRelationship | ( | int | index | ) | const |
This function allows looping through the simulations relationships.
| const SIM_RootData* SIM_Engine::getRootDataFromId | ( | const SIM_RootDataId & | id | ) | const |
Returns either a SIM_Relationship or SIM_Object depending on the information stored in the id parameter.
| void SIM_Engine::getSelection | ( | SIM_ConstDataArray & | data | ) | const |
Gets a list of all selected data in the simulation.
| int SIM_Engine::getSimulationFrame | ( | const SIM_Time & | time | ) | const |
Returns the simulation frame number that corresponds to the given time. The simulation frame number is the number of timesteps that need to be run to get to the specified time, plus one (so that time zero is frame 1).
| const SIM_Object* SIM_Engine::getSimulationObject | ( | int | index | ) | const |
Returns a pointer to the SIM_Object at the specified index. The index value is the current location of the object in the simulations's list of objects. This value will not be the same as the SIM_Object::getObjectId() value.
| const SIM_Object* SIM_Engine::getSimulationObjectFromId | ( | int | objectid | ) | const |
Returns a pointer to the SIM_Object with the specified unique id. This function searches the current list of objects for the specified objectid. If the objectid is not found, this function returns null.
| const SIM_Time SIM_Engine::getSimulationTime | ( | int | frame | ) | const |
Returns the simulation time that corresponds to the given simulation frame.
| const SIM_Time& SIM_Engine::getSimulationTime | ( | ) | const |
Returns the current simulation time.
| const SIM_Time& SIM_Engine::getTimeStep | ( | ) | const |
Returns the time step size.
| int64 SIM_Engine::getTotalMemorySize | ( | ) | const |
Returns the total amount of memory used by all data currently in this simulation, at the current time or in the cache.
| virtual void SIM_Engine::handleExternalNodeChangeSubclass | ( | OP_Node * | changednode, | |
| OP_EventType | eventtype, | |||
| void * | data | |||
| ) | [protected, virtual] |
Override this method to handle changes to external nodes in which we have an interest. The default implementation does nothing.
Reimplemented in DOP_Engine.
| bool SIM_Engine::mergeSimulationFile | ( | const char * | filename, | |
| const SIM_DataFilter & | filter, | |||
| const SIM_ObjectArray & | replaceobjects, | |||
| const OP_Node * | defaultcreator, | |||
| bool | forcecreatortodefault, | |||
| bool | acceptnewobjects, | |||
| bool | matchbyname, | |||
| const char * | nameprefix | |||
| ) |
Loads a simulation state from a file and merges it into the current simulation state. The data that gets loaded is not allowed to do any sharing of data with the current state, since the data id's can't be expected to match. Objects from the file will replace objects from the current state if their object ids match. Objects loaded from the file will be flagged so that they will not be solved in the current timestep. In subsequent timesteps these objects will be solved. The filter parameter specifies which objects stored in the file are merged in.
| virtual void SIM_Engine::objectCreated | ( | SIM_Object * | object | ) | [protected, virtual] |
Initializes a newly created object. This function is called by addSimulationObject(). The default implementation does nothing.
Reimplemented in DOP_Engine.
| virtual void SIM_Engine::objectRemoved | ( | SIM_Object * | object | ) | [protected, virtual] |
Allows special handling of objects that are being removed. This function is called by removeSimulationObject(). The default implementation does nothing.
Reimplemented in DOP_Engine.
| virtual void SIM_Engine::postSimulationStep | ( | ) | [protected, virtual] |
| virtual void SIM_Engine::preSimulationStep | ( | ) | [protected, virtual] |
This function is run before passing each object to its solver. The implementation at this level clears out all temporary data from the simulation objects.
Reimplemented in DOP_Engine.
| void SIM_Engine::removeAllOPInterests | ( | ) | const |
Removes all node interests from the engine.
| void SIM_Engine::removeAllRelationships | ( | int | createdby, | |
| const SIM_RelationshipArray * | except | |||
| ) |
Removes all relationships created by a particular DOP node. If -1 is specified, then all relationships are removed. Relationships in the "except" array are not removed.
| void SIM_Engine::removeRelationship | ( | SIM_Relationship * | rel | ) |
Removes the specified relationship.
| void SIM_Engine::removeRelationship | ( | const char * | name | ) |
Removes the relationship with the specified name.
| void SIM_Engine::removeRelationship | ( | int | index | ) |
Removes the relationship at the specified position.
| void SIM_Engine::removeSimulationObject | ( | SIM_Object * | object | ) |
Removes a SIM_Object from the simulation. This version of this function takes a SIM_Object pointer instead of an index. The pointer is converted to an index and the indexed version of removeSimulationObject() is called.
| void SIM_Engine::removeSimulationObject | ( | int | index | ) |
Removes a SIM_Object from the simulation. The index value is the current location of the object in the simulations's list of objects. This value will not be the same as the SIM_Object::getObjectId() value, and may change when objects are added to or removed from the simulation.
| void SIM_Engine::removeSubStepObject | ( | SIM_Object * | objectattime, | |
| bool | allwithmatchingid | |||
| ) |
Removes an object previously created by createSubStepObject(). If the allwithmatchingid parameter is set to true, not only will the specified object be destroyed, but all other objects with the same object id created using createSubStepObject() will be destroyed. This provides a quick way to destroy all temporary working copies of a particular object.
| virtual void SIM_Engine::resetSimulation | ( | ) | [protected, virtual] |
Resets the simulation to a clean state. This function calls clearSimulation(), then builds a single empty simulation state.
Reimplemented in DOP_Engine.
| void SIM_Engine::saveSimulationFile | ( | const char * | filename, | |
| const SIM_DataFilter & | filter, | |||
| const SIM_ObjectArray & | objects, | |||
| bool | docompress = true | |||
| ) | const |
Schedules some objects to be saved to a files at the end of the current timestep. The filter parameter makes it possible to save only some of the objects to the file. The actual save happens in the postSimulationStep().
| void SIM_Engine::saveSimulationState | ( | ostream & | os, | |
| bool | docompress = true | |||
| ) | const |
Saves the entire current state of the simulation immediately.
| fpreal SIM_Engine::scaleFromMKS | ( | const char * | tounits | ) | const |
Returns the scale factor to convert a value in MKS units into the equivalent value in the provided units.
| fpreal SIM_Engine::scaleToMKS | ( | const char * | fromunits | ) | const |
Returns the scale factor to convert a value in the provided units into the equivalent MKS value.
| void SIM_Engine::setCacheOptions | ( | const SIM_CacheOptions & | o | ) |
Sets the cache options for this simulation.
| void SIM_Engine::setCreatorInfo | ( | int | id, | |
| int | index | |||
| ) |
Set the creator information. These values are automatically reset to (-1, -1) before performing a simulation step.
| virtual bool SIM_Engine::setIsSimulating | ( | bool | issimulating | ) | const [protected, virtual] |
Alerts our owner that we are simulating due to an internally generated need. Returns the previous state
Reimplemented in DOP_Engine.
| void SIM_Engine::setMaxFeedbackIterations | ( | int | max | ) |
Sets the maximum number of allowed feedback iterations.
| void SIM_Engine::setProvideDataHints | ( | bool | providehints | ) |
Specifies whether the engine should provide data hierarchy hints.
| void SIM_Engine::setSimulationTime | ( | const SIM_Time & | t, | |
| bool | resimlasttimestep, | |||
| bool | forceresetsim, | |||
| bool | allowsimulation | |||
| ) |
Sets the current time for the simulation. If the new simulation time is less than the current time, the SIM_Cache is simply set to use its best match for the chosen time. If the new simulation time is greater than the current time, the simulation is stepped forward in time to the new time. The resimlasttimestep parameter causes the most recent cache entry to be deleted before trying to set the current time. This is useful if some parameter of the simulation changes on the current timestep. It causes the timestep to be recooked with the new parameter. This resimulation may also happen if the simulation was interrupted the last time this function was called. The forceresetsim parameter tells the SIM_Engine to reset the simulation before trying to move to the specified time, whether the reset is required or not.
| void SIM_Engine::setTimeStep | ( | const SIM_Time & | time | ) |
Sets the global time step size.
