Detailed Description

All objects in Cinema 4D are derived from the BaseObject class.
Contains methods for the object's position, scale and rotation, as well as for accessing the sub-items of the object (e.g. tags and animation tracks).

Note: Has to be created with Alloc() and destroyed with Free(). Use AutoAlloc to automate the allocation and destruction based on scope.

◆ GetRealDeformMode()

Gets the real deform mode (MODE_ON, MODE_OFF, MODE_UNKNOWN).

Returns: The real deform mode.

◆ SetRealDeformMode()

void SetRealDeformMode ( Int32 mode )

Sets the real deform mode (MODE_ON, MODE_OFF, MODE_UNKNOWN).

Parameters

[in] mode MODE_ON, MODE_OFF or MODE_UNKNOWN.

◆ GetUniqueIP()

Int32 GetUniqueIP ( )

Gets the IP number for the object.
GetUniqueIP() and SetUniqueIP() allow Cinema 4D to identify and track objects between different frames (which is necessary for stuff like object motion blur).

In case of a static generator that is easy: for every frame there is exactly the same structure.
For a particle system however that is different: e.g. there could always be 3 objects (particles), but some might be the same, some might be new ones.
To allow Cinema 4D to track that stuff an IP-like system is used: each object can carry a unique Int32 number and Cinema 4D creates full paths from it, e.g. 5.7.102.43.65.2
This is done 100% internally.

Only generator objects that have variable output or generator objects that use GetHierarchyClone() need to program some extra lines.
Such objects need to set the bit OBJECT_UNIQUEENUMERATION. Then it needs to assign unique Int32 values to all objects returned (except for the top-level object, which is handled by Cinema 4D).

Example:
A generator has 3 objects, but those objects appear and disappear during time. Say that obj3 is child of obj1; obj1 and obj2 are children of main (which is returned). obj2 and obj3 might not be present:

main
  obj1
    [obj3]
  [obj2]

The generator will call:

if (obj1) obj->SetUniqueIP(1);
if (obj2) obj->SetUniqueIP(2);
if (obj3) obj->SetUniqueIP(3);

That is all that is needed. Cinema 4D will recognize which object matches another object at a different time.
If GetHierarchyClone() is called those objects already have a unique numeration. It is only needed to assign a unique value to the top level:

obj1 = GetHierarchyClone(...);
obj2 = GetHierarchyClone(...);
...
if (obj1) obj1->SetUniqueIP(1);
if (obj2) obj2->SetUniqueIP(2);

Returns: The IP number for the object.

Sets the IP number for the object.

Parameters

[in]	type	The type of variable tag to create: VariableTag Types

		BaseTag *	pred = `nullptr`
	)

[in]	variable	true if the tag must be variable, false if it must not be variable or NOTOK if it can be either (if this property does not need to be checked).
[in]	hierarchical	true if the tag must be hierarchical, false if it must not be hierarchical or NOTOK if it can be either (if this property does not need to be checked).
[in]	trans	An alias translator for the operation. Can be nullptr. The caller owns the pointed alias translator.

Returns: true if the tags were copied successfully, otherwise false.

◆ GetCache()

BaseObject* GetCache ( HierarchyHelp * hh = nullptr )

Gets the object from the previously built cache.
Situations can be quite complex in Cinema 4D. For instance GetCache() could return a list of objects.
For example the default Sweep Generator internally has some built-in caches for the sweep surface and for the caps.
The following helper routine can be used to make things easier. It browses through this rather complex hierarchy of objects and caches recursively:

void DoRecursion(BaseObject *op)
{
  BaseObject* tp = op->GetDeformCache();
  if (tp)
  {
    DoRecursion(tp);
  }
  else
  {
    tp = op->GetCache(nullptr);
    if (tp)
    {
      DoRecursion(tp);
    }
    else
    {
      if (!op->GetBit(BIT_CONTROLOBJECT))
      {
        if (op->IsInstanceOf(Opolygon))
        {
          ...
        }
      }
    }
  }
 
  for (tp = op->GetDown(); tp; tp=tp->GetNext())
  {
    DoRecursion(tp);
  }
}

Remember:
Use the above routine only if the caches are already built. It is for instance not safe to use it in a command plugin since the user can have stopped the scene redraw and the building of caches.

See also: CheckCache() GetDeformCache()

Parameters

[in] hh A hierarchy help, usually passed from the calling method parameters, for example ObjectData::GetVirtualObjects(). The caller owns the pointed hierarchy help.
Usually nullptr. Only for some special cases a hierarchy help must be passed.

Returns: The object's previously built cache or nullptr. The object owns the pointed object's cache.
May return nullptr if the cache is not available or is not yet built.

See also: Hierarchy if a plugin needs access to pre-built caches.

◆ GetDeformCache()

BaseObject* GetDeformCache ( )

Gets the previously built cache that has been deformed by an active deformer.
It is important to understand the concept how the deformer cache operates.
For each object in the hierarchy that generates a polygonal cache a deformer cache could also have been created by an active deformer object.
A simple example will help to see how this works:

Take the simple hierarchy shown above, the array generator object creates a virtual hierarchy in the cache, this can be retrieved using GetCache().
This hierarchy is:

From each of the Cube objects a further cache is generated, this time polygonal:

From these the deformer object generates a deformed polygon cache:

So the final hierarchy is:

When a deformer becomes active every object/cache object gets a deform cache (if it was a polygonal object). The deformer cache is always polygonal and is only ever a single object.
Important:
The caches are always built after all plugins and expressions have been called.
If the virtual objects have to be accessed to obtain a polygonal based object it is generally advised to call SendModelingCommand() with MCOMMAND_CURRENTSTATETOOBJECT::
This will rebuild the cache for the passed object if needed, and then clone the polygonal objects.
Another possible solution is to use the Hierarchy class, this will give full access to all virtual objects, or can be used to just rebuild the internal caches.
But be aware that rebuilding the internal caches can cause serious overhead, be time consuming and if called too soon in the pipeline, the caches may need to be rebuilt afterwards.

Returns: The objects previously built deformed cache or nullptr. The object owns the pointed object's cache.
May return nullptr if the cache is not available or is not yet built.

See also: Hierarchy if a plugin needs access to pre-built caches.

◆ GetIsoparm()

LineObject* GetIsoparm ( )

Gets the previously built isoparm representation of the object.

Returns: The isoparm representation of the object or nullptr. The object owns the pointed isoparm.
May return nullptr if the isoparm is not available or is not yet built.

See also: Hierarchy if a plugin needs access to pre-built caches.

◆ SetIsoparm()

Returns: The cache parent or nullptr. The object owns the pointed cache parent.

◆ GetCacheTopParent()

BaseObject* GetCacheTopParent ( ) const

A cache/deform object has no GetUp() link. Instead this method can be called to detect the top cache building parent.

◆ SetPhong()

		Bool	anglelimit,
		Float	angle

Works for generated objects in a cache (e.g. clones generated by a MoGraph cloner) and also for 'real' objects in the document (GetUniqueIP() does not do this).

Note: The ID generation for cache objects is based on GetUniqueIP(), so if two cache objects have the same IP, they will probably also get the same GUID
(unless they are PointObject or PolygonObject with different point or polygon count).
The ID generation for 'real' objects is based on the object's GeMarker, so if an object has no marker it will not return a unique ID.

Note: The matrix of the returned object must not be used. Use the matrix of *this instead.

◆ GetVisibility()
