enum FlowVis::Rendering::Renderer::StreamlineStyle

defines the rendering style of the streamlines

Enumerator:

NORMAL	streamline is rendered normal as a line
TAPERING	thickness of the streamline is adapted to the neighbouring streamlines
GLYPH	glyphs are mapped to the streamline
TEXTURE

Parameters:

data

Member Function Documentation

void FlowVis.Rendering.Renderer.Dispose ( )

Free unmanaged resources.

void FlowVis.Rendering.Renderer.UpdateResources ( )

Call this method after new flow data has been loaded.

void FlowVis.Rendering.Renderer.SetActiveBackground ( int i )

Defines which background texture should be rendered in the method RenderBackground.

Parameters:

index of background which should be rendered

void FlowVis.Rendering.Renderer.EnableTransferForBackground ( bool enable )

Define if the transfer function should be used for the background.

Parameters:

enable

true if transfer function should be enabled

void FlowVis.Rendering.Renderer.RenderBackground ( )

Renders the background texture of the currently active background.

void FlowVis.Rendering.Renderer.UpdateTransfers ( )

Call this method after transfer functions have changed.

void FlowVis.Rendering.Renderer.SetActiveArrowColor ( int i )

Defines which channel is used for the color coding of the arrow plot.

Parameters:

Index of channel which should be used for the color coding

void FlowVis.Rendering.Renderer.EnableArrowSizeCoding ( bool enable )

Defines if the size of the arrows should depend on the velocity.

Parameters:

enable

true if arrow size should be altered by the velocity stored at its point

void FlowVis.Rendering.Renderer.SetArrowAlpha ( float alpha )

Defines the alpha value of the rendered arrows.

Parameters:

alpha

alpha value for rendering arrows

void FlowVis.Rendering.Renderer.RenderArrows	(	int	density,
		float	pointsize

Renders an arrow plot.

void FlowVis.Rendering.Renderer.RenderStreamlines ( )

Renders all streamlines which are stored in the streamline manager.

void FlowVis.Rendering.Renderer.AddStreamline ( Math.Vector3f seedpoint )

Creates a new streamline.

Parameters:

seedpoint

seedpoint of new streamline

clears all streamlines

void FlowVis.Rendering.Renderer.SetStreamlineParameters	(	bool	rungeKutta,
		float	dt
	)

defines the parameters of newly created streamlines

Parameters:

	dt	stepsize for integration
	rungeKutta	if true, runge-kutta is used for integration, otherwise euler-integration is used

void FlowVis.Rendering.Renderer.SetStreamlineStyleParameters	(	float	glyphSize,

	alpha	alpha value for rendering streamlines
	color	color for rendering streamlines

void FlowVis.Rendering.Renderer.SetStreamlineStyle ( StreamlineStyle style )

Sets the rendering style of the streamlines. Some styles only work with evenly spaced streamlines.

Parameters:

style

e.g. normal or tapering

void FlowVis.Rendering.Renderer.GenerateEvenlySpacedStreamlines	(	float	dSep,
		float	dTest
	)

Uses the streamline manager for generating evenly spaced streamlines.

Parameters:
