PaintTool (interface)¶

バージョン 2.0 で追加.

PaintTool is the interface for Painting tools.

注釈

This is a work in progress, needs to be generalized to abstract the type of attribute being painted.

Functions¶

Vec3	computeDisplacementDir ? ( in Ref<PolygonMesh> mesh )
	ensureAttributeExists ! ( io Ref<Geometry> geometry, in Boolean resetValues )
	paintPolygons ! ( io Ref<PolygonMesh> mesh, in GeometryLocation location )
Ref<Geometry>	rayCast ! ( io MouseEvent mouseEvent, io GeometryLocation location, io Mat44 transform, io Vec3 position )
	reset ! ()
	setPointAttribute ! ( in Index i, in Float32 weight, in Vec3 displacementDir, io Ref<PolygonMesh> mesh )

Vec3 PaintTool.computeDisplacementDir? ( in Ref<PolygonMesh> mesh )

Computes the average normal direction within a certain radius around of a hit-point.

mesh	A reference to the PolygonMesh.

PaintTool.ensureAttributeExists! ( io Ref<Geometry> geometry, in Boolean resetValues )

Creates or resets the geometry attributes.

geometry	The geometry to create/reset.
resetValues	If true, reset the attributes.

PaintTool.paintPolygons! ( io Ref<PolygonMesh> mesh, in GeometryLocation location )

Paints polygons mesh attributes.

mesh	A reference to the PolygonMesh.
location	The mesh location.

Ref<Geometry> PaintTool.rayCast! ( io MouseEvent mouseEvent, io GeometryLocation location, io Mat44 transform, io Vec3 position )

Casts a ray in the scene and gets the hit geometry. Returns null if not hit.

mouseEvent	The mousevent event when the user clicks in the viewport.
location	The geometry location (where the geo has been hit).
transform	The geometry transform in the scene.
position	The hit point position, in wolrd coordinates.

PaintTool.reset! ()

Resets all the geometry attributes used for painting.

PaintTool.setPointAttribute! ( in Index i, in Float32 weight, in Vec3 displacementDir, io Ref<PolygonMesh> mesh )

Sets the point attributes of a polygons mesh. The type of attributes depends of the tool : (position + normal for sculpting, color for paiting).

i	The index of the point.
weight	The weight of the attributes.
displacementDir	The average normal direction at this point.
mesh	A reference to the PolygonMesh.

PaintTool.smoothPointAttribute! ( in Index i, in Float32 weight, in Vec3 displacementDir, io Ref<PolygonMesh> mesh )

Smooths the point attributes of a polygons mesh.

i	The index of the point.
weight	The weight of the attributes.
displacementDir	The average normal direction at this point.
mesh	A reference to the PolygonMesh.

PaintTool.toolTransformChanged! ( in Mat44 transform )

Updates the transformation (position and orientation).

transform

The new transform.
