Detailed Description

Streamlines visualise the path of a fluid particle tracking along a vector field.

Streamlines visualise the path of a fluid particle tracking along a vector field. 2-D and 3-D mesh domains are supported. Seed points for streamlines are sampled from elements according to the graphics sampling attributes and tessellation. Streamlines are drawn as lines, scalable ribbons or extruded circles or squares, as specified by the graphics line attributes. The curl of the stream vector field, or fibre sheet and normal, are visualised by the rotation or lateral orientation of the streamline when viewed with non-line shapes.

Member Enumeration Documentation

enum OpenCMISS::Zinc::GraphicsStreamlines::TrackDirection

Enumeration giving the direction streamlines are tracked relative to the stream vector field.

See Also: GraphicsStreamlines::setStreamVectorField

Enumerator
TRACK_DIRECTION_INVALID	Unspecified track direction
TRACK_DIRECTION_FORWARD	following stream_vector_field
TRACK_DIRECTION_REVERSE	the reverse of stream_vector_field is tracked

Member Function Documentation

Field OpenCMISS::Zinc::GraphicsStreamlines::getStreamVectorField ( )

inline

Gets the vector field the streamline is tracking along.

Returns: Handle to stream vector field, or NULL/invalid handle if none or failed.

TrackDirection OpenCMISS::Zinc::GraphicsStreamlines::getTrackDirection ( )

inline

Gets the direction in which streamlines are tracked.

Returns: The current tracking direction, or CMZN_GRAPHICS_STREAMLINES_TRACK_DIRECTION_INVALID on error.

double OpenCMISS::Zinc::GraphicsStreamlines::getTrackLength ( )

inline

Gets the maximum length streamlines are tracked along.

Returns: The track length, or 0.0 if invalid streamlines graphics.

int OpenCMISS::Zinc::GraphicsStreamlines::setStreamVectorField ( const Field & field )

inline

Sets the vector field to track the streamline along. For a 3-D domain with a 3-D coordinate field, can have 3, 6 or 9 components; extra components set the lateral axes for extruded profiles. For a 2-D domain the stream vector may have 2 components.

Parameters

field The field to track the streamline along.

Returns: Status OpenCMISS::Zinc::OK on success, otherwise OpenCMISS::Zinc::ERROR_ARGUMENT.

int OpenCMISS::Zinc::GraphicsStreamlines::setTrackDirection ( TrackDirection trackDirection )

inline

Sets the direction in which streamlines are tracked relative to the stream vector field.

See Also: GraphicsStreamlines::TrackDirection

Parameters

trackDirection The new tracking direction.

Returns: Status OpenCMISS::Zinc::OK on success, otherwise OpenCMISS::Zinc::ERROR_ARGUMENT.

int OpenCMISS::Zinc::GraphicsStreamlines::setTrackLength ( double length )

inline

Sets the maximum length to track streamlines along. Default value is 1.0; generally need to adjust this for scale of model as streamlines can be slow to evaluate.

Parameters

length The maximum length to track streamlines along >= 0.

Returns: Status OpenCMISS::Zinc::OK on success, otherwise OpenCMISS::Zinc::ERROR_ARGUMENT.
