c4d.modules.mograph.C4D_Falloff¶

class c4d.modules.mograph.C4D_Falloff¶: Represents a falloff and allows to sample falloffs.

It is very simple in use: allocate it, call C4D_Falloff.InitFalloff() first then C4D_Falloff.Sample() or C4D_Falloff.MultiSample().

New in version R19.

Many of the methods are there for use within NodeData/ObjectData/ToolData plugins and should be called within their likewise counterparts.

For instance C4D_Falloff.Draw() should be called from within the corresponding ObjectData/ToolData Draw() implementation, then the falloff will be drawn in the viewport.

C4D_Falloff normally needs a container, this is usually the object’s container. From this container it gets and sets its own parameters for the description, though they can be set directly using the helper functions.

`C4D_Falloff.SetTime(self, time[, bc])`	Sets the current falloff time.

Methods Documentation

C4D_Falloff.__init__(self)¶: Creates a new C4D_Falloff.

C4D_Falloff.InitFalloff(self, bc=None, doc=None, op=None)¶

Initializes the falloff.

Warning

Always call before the sample routines.

Note

It is recommended to pass at least one of the parameters, however not compulsory.

Parameters

bc (Optional[c4d.BaseContainer]) – Optional container of the object owning the falloff. If given the FalloffDataData is extracted from this container.
doc (Optional[c4d.documents.BaseDocument]) – Optional document used to retrieve the current time for the animation of the Spline GUI offset.
op (Optional[c4d.BaseObject]) – Optional object used to set the matrix. If no container is given for bc, this object’s container will be used instead.

Return type

bool

Returns

True if successful, otherwise False.

C4D_Falloff.Sample(self, point, usespline=True, weight=0.0)¶

Samples the falloff for any point in space.

Parameters

point (c4d.Vector) – The point to sample in world space.
usespline (bool) – Use the Spline GUI if it exists. Defaults to True.
weight (float) – An optional weight offset. Equivalent of adding this value to the falloff result before clamping.

Return type

float

Returns

The sampled value.

C4D_Falloff.MultiSample(self, points, usespline=True, weight=0.0)¶

Samples the falloff for an array of points in space.

Parameters

points (List[c4d.Vector]) – The array of points to sample in world space.
usespline (bool) – Use the Spline GUI if it exists. Defaults to True.
weight (Optional[float]) – An optional weight offset. Equivalent of adding this value to the falloff result before clamping.

Return type

List[float]

Returns

The sampled values.

C4D_Falloff.AddFalloffToDescription(self, description, bc=None)¶

Adds the falloff to a description.

Note

Use this function within the implementation of NodeData.GetDDescription().

Parameters

description (c4d.Description) – The description to add the falloff GUI to.
bc (Optional[c4d.BaseContainer]) – Optionally pass the container of the object owning the falloff.

Return type

bool

Returns

True if successful, otherwise False.

C4D_Falloff.Message(self, id, bc=None, data=None)¶

Sends messages to the falloff.

Note

Use this function from within the implementation of NodeData.Message() to pass all messages to the falloff.

DRAWPASS_OBJECT	Object pass.
DRAWPASS_BOX	Box pass.
DRAWPASS_HANDLES	Handle pass.
DRAWPASS_HIGHLIGHTS	Highlights pass.
DRAWPASS_XRAY	X-Ray pass.
