SculptBrushToolData.StartStroke(self, strokeCount, data)
StartStroke() is called once at the start of the stroke. It passes the total number of instances of the brush that will be drawn.
The number of instances will change depending on the symmetry mirroring and radial settings.

Use this method to setup any data on your brush that you might want to access from within your ApplyDab() override via BrushDabData.GetBrush().

Calling order for brush stroke methods:
  • StartStroke(): Called once at the start of the stroke.
  • StartStrokeInstance(): Call for each instance of a stroke that will be used. Use this to initialize any data you might need for the duration of the entire brush stroke.
  • StartSymmetry(): Called once before all the instances are about to be drawn for a small mouse movement. This will be called MANY times during a stroke as the mouse moves over the model.
  • StartStrokeInstanceDabs(): Called once before a bunch of consecutive dabs will be draw for a single instance (mirrored brush).
  • StartDab(): Called for each dab that needs to be drawn between 2 mouse locations on the object for a single brush stroke instance.
  • ApplyDab() gets called to process the dab.
  • EndDab()
  • EndStrokeInstanceDabs()
  • EndSymmetry(): Called once when all symmetrical strokes have finished.
  • EndStrokeInstance(): Called for each instance of a stroke that was used.
  • EndStroke()

Note

StartStroke() will only be called if SculptBrushParams.EnableBrushAccess() has been set to True.

Parameters:
  • strokeCount (int) – The number of instances of the brush that will be drawn.
  • data (c4d.BaseContainer) – The data for the brush.
SculptBrushToolData.StartStrokeInstance(self, strokeInstanceID)
Called after StartStroke(). Called once for each brush instance at the start of a stroke.
The number of instances will change depending on the symmetry mirroring and radial settings.

Use this method to allocate any data you may want to access during a brush stroke, that may be specific for each individual instance.
Setup here any data on your brush that you might want to access from within your ApplyDab() override via BrushDabData.GetBrush().

Note

StartStrokeInstance() will only be called if SculptBrushParams.EnableBrushAccess() has been set to True.

Parameters:strokeInstanceID (int) – The ID of the brush instance being drawn.
SculptBrushToolData.StartSymmetry(self)
Called directly before each individual brush instance is about to be handled.
Between this method and EndSymmetry() all the dabs for each instance will be drawn from one mouse location on the surface of the model to another.
This method will be called every time the user moves its mouse over the object on the screen to indicate that a new batch of dabs is going to be drawn.

Use this method to setup any data on your brush that you might want to access from within your ApplyDab() override via BrushDabData.GetBrush().

Note

StartSymmetry() will only be called if SculptBrushParams.EnableBrushAccess() has been set to True.

SculptBrushToolData.StartStrokeInstanceDabs(self, strokeInstanceID)
Called before all the dabs for a single instance are about to be drawn.
After this call all the dabs for just one instance of the brush on the surface will interpolate between the 2 mouse locations on the object then draw all the dabs for that instance.

Use this method to setup any data on your brush that you might want to access from within your ApplyDab() override via BrushDabData.GetBrush().

Note

StartStrokeInstanceDabs() will only be called if SculptBrushParams.EnableBrushAccess() has been set to True.

Parameters:strokeInstanceID (int) – The ID of the brush instance being drawn.
SculptBrushToolData.StartDab(self, strokeInstanceID)
