Modifier Class Reference

#include <object.h>

Class Description

This is the class from which you may derive Object Space and Space Warp (World Space) Modifier plug-ins.

This class is subclassed off of BaseObject so the modifier can put up a graphical representation in the viewport to use as a gizmo.

virtual CoreExport Interval LocalValidity ( TimeValue  t )

virtual

This method returns the validity interval of a modifier.

It is simply the combination of the validity of all the modifier's parameters. It's used to determine when to cache in the pipeline, but is not directly responsible for determining when ModifyObject() is called. ModifyObject() is called when the pipeline needs to be evaluated either because someone sent a REFMSG_CHANGE message or the validity of the object does not include the current time.

If a modifier is not animated it's OK to simply return FOREVER from

this method. In the case where the modifier changes because a user changes a non-animated control in the user interface (for instance a check box), you can cause reevaluation by notifying your dependents of the change, i.e.:

NotifyDependents(FOREVER, PART_ALL, REFMSG_CHANGE);

Parameters

t	The time to calculate the Interval.

See also

Advanced Topics on Intervals.

Reimplemented in SimpleWSMMod, and SimpleMod.

virtual ChannelMask ChannelsUsed ( )

pure virtual

These are channels that the modifier needs in order to perform its modification.

This should at least include the channels specified in ChannelsChanged() but may include more. Note that ChannelsUsed() is called many times but the channels returned should not change on the fly.

Returns

The channels required. See Object Channels.

Sample Code:

{ return GEOM_CHANNEL|TOPO_CHANNEL; }

Implemented in SimpleWSMMod, and SimpleMod.

virtual ChannelMask ChannelsChanged ( )

pure virtual

These are the channels that the modifier actually modifies.

Note that ChannelsChanged() is called many times but the channels returned should not change on the fly.

Returns

The channels that are changed. See Object Channels

Implemented in SimpleWSMMod, and SimpleMod.

virtual bool ChangesSelType ( )

inlinevirtual

If a modifier want to make it possible to switch dynamically between changing the selection type that flows up the stack, or leaving it like it is, it can overwrite this.

The default implementation indicates that it changes the selection type, if the SUBSEL_TYPE_CHANNEL is part of ChannelsChanged(). Note that ChannelsChanged() can not dynamically changed for various reasons.

{ return ChannelsChanged()&SUBSEL_TYPE_CHANNEL ? true : false;}

CoreExport ChannelMask TotalChannelsUsed

(

)

Returns the same value as ChannelsUsed() above except GFX_DATA_CHANNEL will be ORed in if the TOPO_CHANNEL or the TEXMAP_CHANNEL are being used.

CoreExport ChannelMask TotalChannelsChanged

(

)

Returns the same value as ChannelsChanged() above except GFX_DATA_CHANNEL will be ORed in if the TOPO_CHANNEL, the TEXMAP_CHANNEL , or the VERTCOLOR_CHANNEL are being changed.

virtual Class_ID InputType ( )

pure virtual

This is the type of object that the modifier knows how to modify.

Simple modifiers that just modify points of an object can operate on generic 'Deformable' objects. Deformable objects are any type of object that has points. A modifier could also work on a particular type of object such as a TriObject or PatchObject.

Returns

The Class_ID of the item. You can request any Class_ID for your input type. For example, Class_ID(OMNI_LIGHT_CLASS_ID, 0). See Class IDs defined in plugapi.h>.

Implemented in SimpleWSMMod, and SimpleMod.

virtual void NotifyInputChanged ( const Interval &  changeInt, PartID  partID, RefMessage  message, ModContext *  mc  )

inlinevirtual

This method is called when an item in the modifier stack before this modifier sends a REFMSG_CHANGE message via NotifyDependents().

Consider the following example: Assume the modifier stack contains a Sphere Object, then a Bend, then a Edit Mesh. The Edit Mesh modifier does not have a reference to the Bend or the Sphere because it does not officially depend on these items. However it does depend on them in a certain sense, because it modifies the data that these items produce. So, if they change it may affect the modifier. A modifier may build a cache based on its input object. The modifier needs a way to know when to discard this cache because the input object has changed. Whenever one of the items before this modifier in the stack sends out a REFMSG_CHANGE message via NotifyDependents() to indicate it has changed this method is called. The modifier may respond in a way appropriate to it, for example by discarding its cache of the input object. It is not legal, to issue a NotifyDependent()'s in the NotifyInputChanged() method of a modifier, without checking for reentrancy. Imagine, you have an instanced modifier applied to the same object in the stack. Sending a refmsg from the NotifyInputChanged method will cause an endless loop. Simply putting a guard in, that checks for reentrancy should get rid of the problem.

Parameters

changeInt	This is the interval from the message. It is reserved for future use - now it will always be FOREVER.
partID	This is the partID from the message.
message	This is the message sent.
mc	The ModContext for the pipeline that changed. If a modifier is applied to multiple objects, then there are ModApps in each pipeline that it is applied to. These ModApps are pointing to the same modifier. Consider the following example: Say you apply a Bend modifier to a Sphere, a Cylinder and a Box object. There are three ModApps but only one Bend modifier. Then you go to the Sphere and adjust its Radius. This will cause NotifyInputChanged() to be called on the Bend because the Bend's input changed. However only one of its inputs changed - only the Sphere changed and not the Cylinder or the Box. Therefore NotifyInputChanged() will be called once, and the ModContext passed in will be for the Sphere's changed pipeline. It is possible that all three objects could change at the same time. If an instanced float controller was assigned to the radius, width, and height - one parameter for each object - then the controller was adjusted in the function curve editor, all three items would change. In this case NotifyInputChanged() would be called three times on the Bend. Once for each pipeline, once with each ModContext.

{}

virtual void ModifyObject ( TimeValue  t, ModContext &  mc, ObjectState *  os, INode *  node  )

pure virtual

This is the method that actually modifies the input object.

This method is responsible for altering the object and then updating the validity interval of the object to reflect the validity of the modifier.

Parameters

t	The time at which the modification is being done.
mc	A reference to the ModContext.
os	The object state flowing through the pipeline. This contains a pointer to the object to modify.
node	The node the modifier is applied to. This parameter is always NULL for Object Space Modifiers and non-NULL for World Space Modifiers (Space Warps). This is because a given WSM is only applied to a single node at a time whereas an OSM may be applied to several nodes. This may be used for example by particle system space warps to get the transformation matrix of the node at various times.

MAX_DEPRECATED int NeedUseSubselButton

(

)

Deprecated:

This method is no longer used.

virtual BOOL DependOnTopology ( ModContext &  mc )

inlinevirtual

Modifiers that place a dependency on topology should return TRUE for this method.

An example would be a modifier that stores a selection set base on vertex indices. This modifier depends on the indices being intact for it to operate correctly.

Parameters

mc	Reference to the ModContext.

Returns

TRUE if the modifier depends on topology; otherwise FALSE.

{return FALSE;}

static CoreExport bool GetInputType ( ClassDesc *  cd, Class_ID &  inputType  )

static

To determine the input type of a modifier, an instance of the modifier needs to be created.

If the input type for a large number of modifiers are gathered (for example, when opening the modifier panel modifier dropdown list), creating an instance of each modifier is slow. This method creates an instance of the modifier if needed, and caches the input type. Later requests are satisfied via the cached value.

Parameters

cd	[in] The classdesc of the modifier. Valid superclasses are OSM_CLASS_ID and WSM_CLASS_ID.
inputType	[out] The input type of the modifier. See InputType() for a list of the valid values.

Returns

true if a modifier class with the specified SClass_ID and Class_ID was found, and the output inputType was set to a valid value.

virtual void ForceNotify ( Interval &  i )

inlinevirtual

Reimplemented from BaseObject.

    {NotifyDependents(i,ChannelsChanged(),REFMSG_CHANGE );}

virtual IOResult SaveLocalData ( ISave *  isave, LocalModData *  ld  )

inlinevirtual

When a 3ds Max file is being saved, this method is called so that the modifier can save the localData structure that is hung off each ModContext.

If the modifier doesn't store any data in the ModContext it can ignore this method.

Parameters

isave	You may use this pointer to call methods of ISave to write data.
ld	Pointer to the LocalModData for the modifier.

Returns

One of the following values: IO_OK, IO_ERROR.

{ return IO_OK; }  

virtual IOResult LoadLocalData ( ILoad *  iload, LocalModData **  pld  )

inlinevirtual

When a 3ds Max file is being loaded, this method is called so that the modifier can load the LocalModData structure that is hung off each ModContext.

If the modifier doesn't store any data in the ModContext it can ignore this method.

Parameters

iload	You may use this pointer to call methods of ILoad to read data.
pld	A pointer to a pointer in the ModContext. The modifier must set this pointer to point at a new LocalModData derived class.

Returns

One of the following values: IO_OK, IO_ERROR.

{ return IO_OK; }  

CoreExport IOResult Save ( ISave *  isave )

virtual

Implemented by the System.

This method handles saving the modifier name. This method should be called by the derived class BEFORE it saves any chunks. See the sample code below.

Parameters

isave

You may use this pointer to call methods of ISave to write data.

Returns

One of the following values: IO_OK, IO_ERROR.

Sample Code:

IOResult DispMod::Save(ISave *isave)
{
// First save the modifier name by calling the base class version.
    Modifier::Save(isave);
// Then save this modifiers data.
    isave->BeginChunk(BMIO_CHUNK);
    bi.Save(isave);
    isave->EndChunk();
    return IO_OK;
}

In case the modifier changes the object type (basically the os->obj pointer in ModifyObject) and changes the ExtensionChannel, it has to overwrite this method and copy only the channels that it doesn't modify/added already to the new object.

Parameters

fromObj
toObj

{ toObj->CopyAdditionalChannels(fromObj);}

CoreExport SvGraphNodeReference SvTraverseAnimGraph ( IGraphObjectManager *  gom, Animatable *  owner, int  id, DWORD  flags  )

virtual

Remarks

This method is available in release 3.0 and later only.

This method traverses the graph of objects in the 3ds Max scene, adding desired objects to the schematic view. Developers can specialize this behaviour by overriding this method and adding whatever objects are interesting to the schematic view. Objects are added to the schematic view by calling IGraphObjectManager::AddAnimatable(...). Reference lines are added to the schematic view by calling IGraphObjectManager::AddReference(...). Implementers of this method should call it recursively to process other objects in the scene.

See Class IGraphObjectManager.

Parameters

gom	Points to the schematic view window manager.
owner	The owning animatable.
id	This is usually the sub-anim number (but can actually be any value the developer chooses).
flags	See Flags for AddAnimatable() and SvTravereseAnimGraph().

Returns

A SvGraphNodeReference object.

Reimplemented from Animatable.

Reimplemented in SimpleWSMMod.

Default Implementation:

{
    Animatable *owner;
    int subNum;
    MSTR name;
    owner = gNode->GetOwner();
    subNum = gNode->GetID();
    name = owner->SubAnimName(subNum);
    return name;
}

Reimplemented from Animatable.

CoreExport bool SvIsSelected ( IGraphObjectManager *  gom, IGraphNode *  gNode  )

virtual

Returns true if the object is selected in its schematic view.

Reimplemented from Animatable.

CoreExport MultiSelectCallback* SvGetMultiSelectCallback ( IGraphObjectManager *  gom, IGraphNode *  gNode  )

virtual

Remarks

This method is called before a multiple select/deselect operation in the schematic view. Returns a callback used to perform the (de)selection. May return NULL if this object cannot be selected in some principle editor outside the schematic view.

Parameters

gom	Points to the schematic view window manager.
gNode	Points to the node in the schematic view.

Returns

A pointer to the callback object. See Class MultiSelectCallback.

Default Implementation:

{ return NULL; }

Reimplemented from Animatable.

CoreExport bool SvCanSelect ( IGraphObjectManager *  gom, IGraphNode *  gNode  )

virtual

Remarks

Returns true if this object can be selected in some editor (viewport, material editor, plug-in specific editor, etc.). Selection is actually accomplished by via the SvGetMultiSelectCallback(...) mechanism described above.

Parameters

gom	Points to the schematic view window manager.
gNode	Points to the node in the schematic view.

Default Implementation:

{ return false; }

Reimplemented from Animatable.
