Detailed Description

Base class for the sculpt brush plug-ins.

The sculpt brush modifies the sparse vertex delta stored in the Sculpt node's "delta_points" plug. At the beginning of the stroke, a BrushSculptUserData derived object must be created and returned by the sculpt_geometry_user_data() method. This object will contain the data and the sculpt callback to update the delta of the vertices in reference space. The reference space is the mesh in its initial position (ref pose).

Member Function Documentation

◆ deactivate()

void maquina::BrushSculptPlugin::deactivate ( )

overridevirtual

Reimplemented from maquina::BrushPlugin.

◆ delta_points()

virtual SceneConst maquina::BrushSculptPlugin::delta_points ( )

inlinevirtual

Get the current delta points from the deformer.

◆ preserve_edges()

virtual bool maquina::BrushSculptPlugin::preserve_edges ( )

inlinevirtual

Return true if the sculpt weight on edge vertices must be 0 or false if nothing special must be done on edges.

◆ reference()

virtual SceneConst maquina::BrushSculptPlugin::reference ( )

inlinevirtual

Return the reference scene (as it with no modification, no animation)

◆ set_delta_points()

virtual void maquina::BrushSculptPlugin::set_delta_points ( const SceneConst & )

inlinevirtual

Set delta points to the deformer.

◆ stroke_begin()

void maquina::BrushSculptPlugin::stroke_begin ( int modifiers )

overridevirtual

Called when the stroke is beginning.

Called by BrushPlugin::on_mouse_move. To be implemented by the plug-in.

Reimplemented from maquina::BrushPlugin.

◆ stroke_update()

void maquina::BrushSculptPlugin::stroke_update	(	bool	first,
		bool	finished
	)

overridevirtual

Called when the brush moves or have been released.

finished is true if the stroke is over.

Called by BrushPlugin::on_mouse_press and BrushPlugin::on_mouse_move. To be implemented by the plug-in.

Reimplemented from maquina::BrushPlugin.

◆ user_data()

virtual std::shared_ptr<BrushSculptUserData> maquina::BrushSculptPlugin::user_data	(	const SparseBufferV3f &	delta_points,
		const BrushPlugin::GeometryData &	geometry,
		const BufferConstM33f &	vertex_space,
		const std::shared_ptr< SceneConst > &	reference
	)

inlinevirtual

Create a BrushSculptUserData object for a geometry.

This method is implemented by the plug-in and is called by the BrushSculptPlugin object during the stroke_begin(). It must create and return a BrushSculptUserData derived object with all the needed data and the sculpting callback. It can return nullptr if no sculpting will be performed on this geometry.

◆ vertex_space()

virtual SceneConst maquina::BrushSculptPlugin::vertex_space ( )

inlinevirtual

Return a scene with for every geometries, an array of vertex space rotation matrices.
