Method Detail

getAllPropertyInfo

public PropertyList getAllPropertyInfo()

Description copied from interface: HasProperties

Returns a list giving static information about all properties exported by this object.

Specified by:

getAllPropertyInfo in interface HasProperties

Overrides:

getAllPropertyInfo in class ModelComponentBase

Returns:

static information for all exported properties

getVisualization

public ScalarMeshField.Visualization getVisualization()

setVisualization

public void setVisualization(ScalarMeshField.Visualization vis)

getVisualizationRange

public Range getVisualizationRange()

getColorInterpolation

public Renderer.ColorInterpolation getColorInterpolation()

setColorInterpolation

public void setColorInterpolation(Renderer.ColorInterpolation interp)

getColorMap

public ColorMapBase getColorMap()

setColorMap

public void setColorMap(ColorMapBase map)

setRenderRange

public void setRenderRange(ScalarRange range)

getRenderRange

public ScalarRange getRenderRange()

getValue

public double getValue(FemFieldPoint fp)

Returns the value of the this field at a specified FEM field point.

Specified by:

getValue in interface ScalarFieldComponent

Parameters:

fp - point at which value is requested

Returns:

value at the point

getValue

public abstract double getValue(Point3d pos)

Returns the value of the this field at a specified spatial position.

Specified by:

getValue in interface ScalarFieldComponent

Parameters:

pos - position at which value is requested

Returns:

value at the position

getValueRange

public DoubleInterval getValueRange()

Returns the range of all values in this field, including the default value.

clearAllValues

public abstract void clearAllValues()

Clear all values defined for the features (e.g., vertices, faces) associated with this field. After this call, the field will have a uniform value defined by its defaultValue.

getDefaultValue

public double getDefaultValue()

Returns the default value for this field. See setDefaultValue(double).

Returns:

default value for this field

setDefaultValue

public void setDefaultValue(double value)

Sets the default value for this field. Default values are used at features (e.g., vertices, faces) for which values have not been explicitly specified.

Parameters:

value - new default value for this field

createRenderProps

public RenderProps createRenderProps()

Description copied from interface: HasRenderProps

Factory method to create render properties appropriate to this object.

Specified by:

createRenderProps in interface HasRenderProps

Returns:

new render properties for this object

createDefaultRenderProps

public static RenderProps createDefaultRenderProps()

prerender

public void prerender(RenderList list)

Description copied from interface: IsRenderable

Called prior to rendering to allow this object to update the internal state required for rendering (such as by caching rendering coordinates). The object may add internal objects to the list of objects being rendered, by calling

list.addIfVisible (obj);

for each of the objects in question.

Specified by:

prerender in interface IsRenderable

Parameters:

list - list of objects to be rendered

render

public void render(Renderer renderer,
                   int flags)

Description copied from interface: IsRenderable

Render this object using the functionality of the supplied Renderer.

Specified by:

render in interface IsRenderable

Parameters:

renderer - provides the functionality used to perform the rendering.

flags - flags that may be used to control different aspects of the rendering. Flags are defined in Renderer and currently include Renderer.HIGHLIGHT and Renderer.SORT_FACES.
