virtual void makVrv::DtFilledPolygon::setFillType ( FillType type )

virtual

Set the quad fill type. Calling fill type resets the fill parameter, thus the fill parameter must be reset after calling setFillType.

Implements makVrv::DtFilledPolygonInterface.

virtual FillType makVrv::DtFilledPolygon::fillType ( ) const

virtual

Get the fill type.

Implements makVrv::DtFilledPolygonInterface.

virtual void makVrv::DtFilledPolygon::setFillParameter	(	unsigned int	param,
		unsigned int	fullStipplePattern[32] = `0`
	)

overridevirtual

Set a 32x32 stipple pattern as the fill. If the full stippledPattern (aka a full 32x32 bit array) the initial param is ignored.

Implements makVrv::DtFilledPolygonInterface.

virtual void makVrv::DtFilledPolygon::setFillTexture ( DtTextureInterface * textureHandle )

overridevirtual

Sets the texture to fill the polygon with. The texture is visualized to be centered in the polygon and to fill the polygon with minimal tiling.

Implements makVrv::DtFilledPolygonInterface.

Implements makVrv::DtFilledPolygonInterface.

virtual void makVrv::DtFilledPolygon::setFillPatternFrequency ( float frequency )

overridevirtual

Sets the fill pattern tiling frequency. The frequency needs to be 1 / x where x is a whole number. examples: frequency = 1.0 : the tiled pattern will tile normally frequency = 0.5 : the tiled pattern will appear half as often.

Implements makVrv::DtFilledPolygonInterface.

virtual void makVrv::DtFilledPolygon::setEventsEnabled	(	bool	enabled,
		unsigned long	long = `0`

Get whether events are already enabled.

Implements makVrv::DtFilledPolygonInterface.

virtual

Set one vertex position.

void makVrv::DtFilledPolygon::set3DDirectionAndLength	(	unsigned int	index,
		float	x,
		float	y,
		float	z,
		float	l
	)

virtual

Sets an optional 3D direction with a 2D length value for a vertex.

Parameters

index	the index of the vertex to get the position of
x	x component of the position
y	y component of the position
z	z component of the position

overridevirtual

Does uv coordinate projection based on the current vertex positions and the given projection parameters.

virtual void makVrv::DtFilledPolygon::setGroup ( int )

virtual

Sets the group for Z-Ordering.

Implements makVrv::DtFilledPolygonInterface.

virtual void makVrv::DtFilledPolygon::triangulate ( )

As long as there are a divisible by three of triangle proxies, reworks them to be a triangle of three related points, using the center as an anchor point.

Implements makVrv::DtFilledPolygonInterface.

virtual void makVrv::DtFilledPolygon::set2DPositionsTriangles ( const std::vector< float > & vertices )

virtual

Set the number of vertices and their positions. This method is to be used instead of set2DPositions. This method does not calculate/use the center of the polygon as the third vertex for each two passed in like set2DPositions. It expects the triangles to already be calculated, the loop in here skips 6 floats per iteration.

Implements makVrv::DtFilledPolygonInterface.

virtual void makVrv::DtFilledPolygon::setVertexCountTriangles ( unsigned int vertexCount )

virtual

Set the number of vertices, any newly created vertices will be black and add 0,0,0 so setColor/setPosition may be necessary.This method is used instead of setVertexCount when you are calling set2DPositionsTriangles.

Implements makVrv::DtFilledPolygonInterface.

virtual void makVrv::DtFilledPolygon::slot_pickerDestroyed ( )

protectedvirtual

Called when the widget picker is destroyed, clears out pickable segment list and sets a flag to no longer use the picker.
