FieldLayer.InitSampling(self, info)¶

Initializes field sampling.

Warning

Must be called before Sample() is invoked.

Parameters: info (c4d.modules.mograph.FieldInfo) – The FieldInfo to initialize sampling with.

FieldLayer.FreeSampling(self, info)¶

Frees any data allocated in InitSampling().

Warning

Must be called after sampling is finished.

Parameters: info (c4d.modules.mograph.FieldInfo) – The FieldInfo instance used for sampling.

FieldLayer.Sample(self, input, output, info)¶

Samples the field layer.

Warning

InitSampling() must be called before. FreeSampling() must be called once sampling is complete.

Parameters

input (c4d.modules.mograph.FieldInput) – The points to sample in global space.
output (c4d..modules.mograph.FieldOutputBlock) – The output result values, should be allocated prior to usage.
info (c4d.modules.mograph.FieldInfo) – The FieldInfo to sample with. It should match the info used with InitSampling().

FieldLayer.Aggregate(self, input, output, info)¶: Private

FieldLayer.GetLayerFlags(self)¶

Gets the layer’s execution and display flags.

Return type

int

Returns

The layer flags:

FIELDLAYER_FLAG_NONE	None.
FIELDLAYER_FLAG_SKIP	Layer calculation is disabled, e.g. the linked object on a standard layer’s deform mode is false.
FIELDLAYER_FLAG_ERRORSKIP	Layer calculation is disabled due to a non critical error in `InitSampling()` or as user specified.
FIELDLAYER_FLAG_HIDE	Layer should be completely ignored from both calculation and GUI display, e.g. the linked object has been deleted.
FIELDLAYER_FLAG_MODIFYDATA	The layer modifies existing data and needs the values from layers beneath it in the layer list.
FIELDLAYER_FLAG_PRESERVEALPHA	The layer does not adjust the existing alpha and its color changes should be applied ignoring any alpha values.
FIELDLAYER_FLAG_NOCHILDVALUE	Children of the layer do not output their value.
FIELDLAYER_FLAG_NOCHILDCOLOR	Children of the layer do not output their color.
FIELDLAYER_FLAG_NOCHILDDIRECTION	Children of the layer do not output their direction.
FIELDLAYER_FLAG_NOCHILDROTATION	Children of the layer do not output their rotation.
FIELDLAYER_FLAG_TEMPORARY	Do not save the layer with the list or duplicate it (outside of undo).

FieldLayer.SetLayerFlags(self, flags, state=True)¶

Sets the layer’s execution and display flags.

Parameters

flags (int) –

The layer flag to set:

FIELDLAYER_FLAG_NONE	None.
FIELDLAYER_FLAG_SKIP	Layer calculation is disabled, e.g. the linked object on a standard layer’s deform mode is false.
FIELDLAYER_FLAG_ERRORSKIP	Layer calculation is disabled due to a non critical error in `InitSampling()` or as user specified.
FIELDLAYER_FLAG_HIDE	Layer should be completely ignored from both calculation and GUI display, e.g. the linked object has been deleted.
FIELDLAYER_FLAG_MODIFYDATA	The layer modifies existing data and needs the values from layers beneath it in the layer list.
FIELDLAYER_FLAG_PRESERVEALPHA	The layer does not adjust the existing alpha and its color changes should be applied ignoring any alpha values.
FIELDLAYER_FLAG_NOCHILDVALUE	Children of the layer do not output their value.
FIELDLAYER_FLAG_NOCHILDCOLOR	Children of the layer do not output their color.
FIELDLAYER_FLAG_NOCHILDDIRECTION	Children of the layer do not output their direction.
FIELDLAYER_FLAG_NOCHILDROTATION	Children of the layer do not output their rotation.
FIELDLAYER_FLAG_TEMPORARY	Do not save the layer with the list or duplicate it (outside of undo).

state (bool) – True to set, False to clear.

FieldLayer.GetLinkedObject(self, doc)¶

Gets the linked object.

Parameters: doc (c4d.documents.BaseDocument) – The document the FieldLayer belongs to.
Return type: c4d.BaseList2D
Returns: The linked object.

FieldLayer.SetLinkedObject(self, link)¶

Sets the linked object.

Parameters: link (c4d.BaseList2D) – The object to link.

FieldLayer.GetMaskHead(self)¶

If the c4d.FieldLayer has a mask then this retrieve the list head containing the mask layers.

Return type: c4d.GeListHead
Returns: The GeListHead containing the mask layers, None if masks aren’t active on this layer.

FieldLayer.AddMask(self)¶

Adds a mask to the c4d.FieldLayer, if a mask already exists then this will do nothing.

Return type: bool
Returns: True on success.

FieldLayer.RemoveMask(self, link)¶

Removes the mask on the c4d.FieldLayer, if no mask exists then this will do nothing.

Note

In c++ the parameter link is named deleteLayers, it’s probable that it will change as well in Python.

Parameters: link (bool) – True to delete the layers in the mask, False to retain them so that when enabled again via c4d.AddMask() the layers will reappear.
