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 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
fieldThe 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
trackDirectionThe 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
lengthThe maximum length to track streamlines along >= 0.
Returns
Status OpenCMISS::Zinc::OK on success, otherwise OpenCMISS::Zinc::ERROR_ARGUMENT.
