Function Documentation

generateAxisMesh()

std::unique_ptr< Mesh > inviwo::plot::generateAxisMesh	(	const vec2 &	startPos,
		const vec2 &	endPos,
		const vec4 &	color,
		const size_t &	pickingId = std::numeric_limits<size_t>::max()
	)

No picking buffer will be generated if pickingId = std::numeric_limits<size_t>::max()

generateAxisMesh3D()

std::unique_ptr< Mesh > inviwo::plot::generateAxisMesh3D	(	const vec3 &	startPos,
		const vec3 &	endPos,
		const vec4 &	color,
		const size_t &	pickingId = std::numeric_limits<size_t>::max()
	)

No picking buffer will be generated id pickingId = std::numeric_limits<size_t>::max()

generateMajorTicksMesh()

std::unique_ptr< Mesh > inviwo::plot::generateMajorTicksMesh	(	const AxisSettings &	settings,
		const vec2 &	startPos,
		const vec2 &	endPos
	)

creates a mesh containing major ticks for an axis extending from start to end position

Parameters

settings	axis property used for tick settings
startPos	start position of axis
endPos	end position of axis

Returns

mesh containing of ticks, each tick is represented by two positions and matching colors

generateTicksMesh()

std::unique_ptr< Mesh > inviwo::plot::generateTicksMesh	(	const std::vector< double > &	tickMarks,
		dvec2	axisRange,
		const vec3 &	startPos,
		const vec3 &	endPos,
		const vec3 &	tickDirection,
		float	tickLength,
		TickStyle	style,
		const vec4 &	color,
		bool	flip
	)

utility function to create a mesh for a given set of tick mark positions

Parameters

tickMarks	positions of tick marks in same coordinate system as the axis range
axisRange	min/max values of the axis
startPos	start position of axis (spatial coordinates)
endPos	end position of axis (spatial coordinates)
tickDirection	direction of ticks pointing outwards (spatial coordinates)
tickLength	length of the ticks
style	tick style (none, inside, outside, both)
color	tick color
flip	if true, the orientation of ticks is flipped (only affects inside/outside ticks). This is, e.g., used for axis at the top (default tick outside location is bottom/left)

Returns

mesh containing of ticks, each tick is represented by two positions and matching colors

getMajorTickPositions()

std::vector<double> inviwo::plot::getMajorTickPositions ( const AxisSettings &  settings, size_t  maxTicks = 1000  )

inline

returns tick positions along the axis range defined in the axis property

Parameters

settings	axis property used for tick settings
maxTicks	maximum number of ticks

Returns

positions of tick marks
