Specified by:

transformGeometry in interface TransformableGeometry

Overrides:

transformGeometry in class DynamicComponentBase

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

Overrides:

transformGeometry in class Frame

Parameters:

gtr - transformer implementing the transform

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

flags - specifies conditions associated with the transformation

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

Overrides:

addTransformableDependencies in class Frame

Parameters:

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

flags - specifies conditions associated with the transformation

createMarker

public FrameMarker createMarker(Line ray)

Description copied from class: Frame

Creates a FrameMarker attached to this frame and adds it to the frame's markers list. If the frame is an instance of HasSurfaceMesh, the marker's position is determined the nearest intersection of the specified ray and the mesh, with null being returned if there is no intersection. Otherwise, the marker's position is set to the frame's origin.

Specified by:

createMarker in interface IsMarkable

Overrides:

createMarker in class Frame

Parameters:

ray - to line intersect with the frame's surface mesh to determine the marker location

Returns:

created marker, or null if there is no mesh-ray intersection

getSurfaceMesh

public PolygonalMesh getSurfaceMesh()

Description copied from interface: HasSurfaceMesh

Returns the surface mesh associated with this component, or null if no mesh exists. If multiple surface meshes exist, this should be first one in the array returned by HasSurfaceMesh.getSurfaceMeshes().

Specified by:

getSurfaceMesh in interface HasSurfaceMesh

Returns:

component's (primary) surface mesh

numSurfaceMeshes

public int numSurfaceMeshes()

Description copied from interface: HasSurfaceMesh

Returns the number of surfaces meshes associated with this component, or 0 if no meshes exist. If HasSurfaceMesh.getSurfaceMesh() returns null, then this method should return 0.

Specified by:

numSurfaceMeshes in interface HasSurfaceMesh

Returns:

number of surface meshes associated with this component

getSurfaceMeshes

public PolygonalMesh[] getSurfaceMeshes()

Description copied from interface: HasSurfaceMesh

Returns an array listing all the (non-null) surface meshes associated with this component, or a zero-length array if there are none. If HasSurfaceMesh.getSurfaceMesh() returns null, then a zero-length array should be returned.

Specified by:

getSurfaceMeshes in interface HasSurfaceMesh

Returns:

surface meshes associated with this component

iterator

public java.util.Iterator<ModelComponent> iterator()

hasState

public boolean hasState()

Description copied from class: DynamicComponentBase

Queries if this component has state. Structure change events involving components that have state will cause the current state history of of the system to be cleared.

Specified by:

hasState in interface HasNumericState

Specified by:

hasState in interface ModelComponent

Overrides:

hasState in class DynamicComponentBase

Returns:

true if this component has state

getImagePath

public java.lang.String getImagePath()

setImagePath

public void setImagePath(java.lang.String path)

isDuplicatable

public boolean isDuplicatable()

Description copied from interface: CopyableComponent

Returns true if this component can be duplicated. Duplication means that we can expect to be able to make a complete copy of the component along with all it's external references. This method should return true if and only if CopyableComponent.getCopyReferences(java.util.List<artisynth.core.modelbase.ModelComponent>, artisynth.core.modelbase.ModelComponent) returns true.

This method is not currently used. It is intended to provide a faster way of determining if a component can be duplicated, without having to use CopyableComponent.getCopyReferences(java.util.List<artisynth.core.modelbase.ModelComponent>, artisynth.core.modelbase.ModelComponent) to build the list of copy references.

Specified by:

isDuplicatable in interface CopyableComponent

Overrides:

isDuplicatable in class Frame

Returns:

true if this component can be duplicated.

copy

public DicomViewer copy(int flags,
                        java.util.Map<ModelComponent,ModelComponent> copyMap)

Description copied from interface: CopyableComponent

Create a copy of this component. If COPY_REFERENCES is set in flags, then any component referenced by this component should itself be set to a copy. This should be done first checking copyMap for an existing copy of the referenced component. If there is no existing copy, then a copy should be created by calling copy recursively and adding the new copy to copyMap.

Specified by:

copy in interface CopyableComponent

Overrides:

copy in class Frame

Parameters:

flags - flags to control the copying

copyMap - map to possible existing instances of referenced components

Returns:

copy of this component
