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 RenderableComponentBase

Returns:

static information for all exported properties

getRenderGrid

public boolean getRenderGrid()

Queries whether or not grid rendering is enabled.

Returns:

true if grid rendering is enabled

setRenderGrid

public void setRenderGrid(boolean enable)

Sets whether or not rendering is enabled for this grid. If enabled, the grid is rendered in the viewer.

Parameters:

enable - if true, enables grid rendering

getRenderVertices

public boolean getRenderVertices()

Queries whether or not vertex rendering is enabled.

Returns:

true if vertex rendering is enabled

setRenderVertices

public void setRenderVertices(boolean enable)

Sets whether or not vertex rendering is enabled for this grid. If enabled, the vertices are rendered whenever grid rendering is enabled.

Parameters:

enable - if true, enables vertex rendering

getRenderRanges

public java.lang.String getRenderRanges()

Returns a string describing the x, y, z vertex ranges used when rendering this grid. See setRenderRanges(java.lang.String) for a more detailed description.

Returns:

string describing the render ranges

See Also:

setRenderRanges(java.lang.String)

setRenderRanges

public void setRenderRanges(java.lang.String ranges)

Specifies the x, y, z vertex ranges used when rendering this grid. The signed distance grid will have numVX X numVY X numVZ vertices in the x, y, z directions, where numVX, numVY, and numVZ are each one greater than the x, y, z cell resolution values returned by the InterpolatingGridBase.getResolution() method of the distance grid itself. In general, the range string should contain three range specifications, one for each axis, where each specification is either * (all vertices), n:m (vertices in the index range n to m, inclusive), or n (vertices only at index n). A range specification of "* * *" (or "*") means draw all vertices, which is the default behavior. Other examples include:

  "* 7 *"      - all vertices along x and z, and those at index 7 along y
  "0 2 3"      - a single vertex at indices (0, 2, 3)
  "0:3 4:5 *"  - all vertices between indices 0 and 3 along x, and 4 and 5
                 along y
 

Parameters:

ranges - describing the render ranges

Throws:

java.lang.IllegalArgumentException - if the range syntax is invalid or out of range

addTransformableDependencies

public void addTransformableDependencies(TransformGeometryContext context,
                                         int flags)

Description copied from interface: TransformableGeometry

Adds to context any transformable components which should be transformed as the same time as this component. This will generally include descendant components, and may also include other components to which this component is connected in some way.

This method is generally called from with the TransformGeometryContext.apply(maspack.geometry.GeometryTransformer, int) method of a TransformGeometryContext.

Specified by:

addTransformableDependencies in interface TransformableGeometry

Parameters:

context - context information, to which the dependent components are added.

flags - specifies conditions associated with the transformation

transformGeometry

public void transformGeometry(AffineTransform3dBase X)

Description copied from interface: TransformableGeometry

Applies an affine transformation to the geometry of this component. This method should be equivalent to

 TransformGeometryContext.transform (this, X, 0);
 

Specified by:

transformGeometry in interface TransformableGeometry

Parameters:

X - affine transformation to apply to the component

transformGeometry

public void transformGeometry(GeometryTransformer gtr,
                              TransformGeometryContext context,
                              int flags)

Description copied from interface: TransformableGeometry

Transforms the geometry of this component, using the geometry transformer gtr to transform its individual attributes. The context argument supplies information about what other components are currently being transformed, and also allows the requesting of update actions to be performed after all transform called have completed. The context is also the usual entity that calls this method, from within its TransformGeometryContext.apply(maspack.geometry.GeometryTransformer, int) method. The argument flags provides flags to specify various conditions associated with the the transformation. At present, the available flags are TransformableGeometry.TG_SIMULATING and TransformableGeometry.TG_ARTICULATED.

This method is not usually called directly by applications. Instead, it is typically called from within the TransformGeometryContext.apply(maspack.geometry.GeometryTransformer, int) method of the context, which takes care of the various operations needed for a complete transform operation, including calling TransformableGeometry.addTransformableDependencies(artisynth.core.modelbase.TransformGeometryContext, int) to collect other components that should be transformed, calling TransformableGeometry.transformGeometry(maspack.matrix.AffineTransform3dBase) for each component, notifying component parents that the geometry has changed, and calling any requested TransformGeometryActions. More details are given in the documentation for TransformGeometryContext.apply(maspack.geometry.GeometryTransformer, int).

TransformGeometryContext provides a number of static convenience transform methods which take care of building the context and calling apply() for a specified set of components.

This method should not generally call transformGeometry() for its descendant components. Instead, descendants needing transformation should be specified by adding them to the context in the method TransformableGeometry.addTransformableDependencies(artisynth.core.modelbase.TransformGeometryContext, int).

Specified by:

transformGeometry in interface TransformableGeometry

Parameters:

gtr - transformer implementing the transform

context - context information, including what other components are being transformed

flags - specifies conditions associated with the transformation

getGrid

public abstract InterpolatingGridBase getGrid()

setGrid

public void setGrid(InterpolatingGridBase gridBase)

defaultRenderProps

public static RenderProps defaultRenderProps(GridCompBase comp)

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

Overrides:

createRenderProps in class RenderableComponentBase

Returns:

new render properties for this object

updateBounds

public void updateBounds(Vector3d pmin,
                         Vector3d pmax)

Description copied from interface: IsRenderable

Update the minimum and maximum points for this object. In an x-y-z coordinate system with x directed to the right and y directed upwards, the minimum and maximum points can be thought of as defining the left-lower-far and right-upper-near corners of a bounding cube. This method should only reduce the elements of the minimum point and increase the elements of the maximum point, since it may be used as part of an iteration to determine the bounding cube for several different objects.

Specified by:

updateBounds in interface IsRenderable

Overrides:

updateBounds in class RenderableComponentBase

Parameters:

pmin - minimum point

pmax - maximum point

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

Overrides:

prerender in class RenderableComponentBase

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

Specified by:

render in class RenderableComponentBase

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.
