Detailed Description

A glyph is a static graphics object used to visualise a point in space.

A glyph is a static graphics object used to visualise a point in space, e.g. point, line, sphere, axes etc. Note that the appearance of some glyphs depend on attributes of point graphics used to draw them: circular glyphs (sphere, cylinder etc.) use the circle divisions of the tessellation object, axes with labels use the font. Derived glyph types implement custom axes and spectrum colour bar.

Member Enumeration Documentation

enum OpenCMISS::Zinc::Glyph::RepeatMode

An enum defining how glyphs are repeatedly displayed at points.

See Also

Graphicspointattributes

Enumerator
REPEAT_MODE_INVALID	Unspecified glyph repeat mode
REPEAT_MODE_NONE	default cmzn_glyph_repeat_mode normal single glyph display, no repeat
REPEAT_MODE_AXES_2D	draw glyph 2 times treating each axis as a separate vector. Base size and scale factors are applied separately to each axis.
REPEAT_MODE_AXES_3D	draw glyph 3 times treating each axis as a separate vector. Base size and scale factors are applied separately to each axis.
REPEAT_MODE_MIRROR	draw glyph twice, second mirrored about axis1 == 0.0. Commonly used with a signed_scale_field to visualise stress and strains using pairs of arrow glyphs pointing inward for compression, outward for tension. Suitable glyphs (line, arrow, cone) span from 0 to 1 along their first axis. Not suitable for sphere, cube etc. which are symmetric about 0.0 on axis 1. In this mode the label is only shown for the first glyph and the label offset is not reversed with the glyph. See Also Graphicspointattributes::setSignedScaleField

enum OpenCMISS::Zinc::Glyph::ShapeType

An enumeration defining standard glyph shapes which can be used as an alternative means to specify the glyph used in graphics.

Enumerator

SHAPE_TYPE_AXIS	line arrow from 0,0,0 to 1,0,0, head 0.1 long unit width
SHAPE_TYPE_AXIS_SOLID	solid arrow from 0,0,0 to 1,0,0, head 0.1 long unit width
SHAPE_TYPE_CONE	unit diameter cone from base 0,0,0 to apex 1,0,0, open base
SHAPE_TYPE_CONE_SOLID	unit diameter cone from base 0,0,0 to apex 1,0,0, closed base
SHAPE_TYPE_CROSS	3 crossed lines on each axis, centre 0,0,0
SHAPE_TYPE_CUBE_SOLID	solid unit cube centred at 0,0,0 and aligned with axes
SHAPE_TYPE_CUBE_WIREFRAME	wireframe unit cube centred at 0,0,0 and aligned with axes
SHAPE_TYPE_CYLINDER	unit diameter cylinder from 0,0,0 to 1,0,0, open ends
SHAPE_TYPE_CYLINDER_SOLID	unit diameter cylinder from 0,0,0 to 1,0,0, closed ends
SHAPE_TYPE_DIAMOND	unit regular octahedron centred at 0,0,0; a degenerate sphere
SHAPE_TYPE_LINE	line from 0,0,0 to 1,0,0
SHAPE_TYPE_POINT	a single point at 0,0,0
SHAPE_TYPE_SHEET	unit square in 1-2 plane centred at 0,0,0
SHAPE_TYPE_SPHERE	unit sphere centred at 0,0,0
SHAPE_TYPE_AXES	unit line axes without labels
SHAPE_TYPE_AXES_123	unit line axes with labels 1,2,3
SHAPE_TYPE_AXES_XYZ	unit line axes with labels x,y,z
SHAPE_TYPE_AXES_COLOUR	unit line axes with materials red, green, blue
SHAPE_TYPE_AXES_SOLID	unit solid arrow axes without labels
SHAPE_TYPE_AXES_SOLID_123	unit solid arrow axes with labels 1,2,3
SHAPE_TYPE_AXES_SOLID_XYZ	unit solid arrow axes with labels x,y,z
SHAPE_TYPE_AXES_SOLID_COLOUR	unit solid arrow axes with materials red, green, blue

Member Function Documentation

GlyphAxes OpenCMISS::Zinc::Glyph::castAxes ( )

inline

If the glyph is type axes, returns the type-specific handle.

Returns

Handle to derived axes glyph, or NULL/invalid handle if wrong type or failed.

GlyphColourBar OpenCMISS::Zinc::Glyph::castColourBar ( )

inline

If the glyph is type colour bar, returns the type-specific handle.

Returns

Handle to derived colour bar glyph, or NULL/invalid handle if wrong type or failed.

cmzn_glyph_id OpenCMISS::Zinc::Glyph::getId ( ) const

inline

Return the C handle of the Glyph object.

Returns

C handle of Glyph if this objects is valid, 0 otherwise.

char* OpenCMISS::Zinc::Glyph::getName ( )

inline

Return an allocated string containing glyph name.

Returns

Allocated string containing glyph name, or NULL on failure. Up to caller to free using cmzn_deallocate().

bool OpenCMISS::Zinc::Glyph::isManaged ( )

inline

Get managed status of glyph in its owning glyph module.

See Also

Glyph::setManaged

Returns

true if glyph is managed, otherwise 0 false.

bool OpenCMISS::Zinc::Glyph::isValid ( ) const

inline

Check if this is a valid Glyph object.

Returns

Status True if object is valid, false otherwise.

int OpenCMISS::Zinc::Glyph::setManaged ( bool  value )

inline

Set managed status of glyph in its owning glyph module. If set (managed) the glyph will remain indefinitely in the glyph module even if no external references are held. If not set (unmanaged) the glyph will be automatically removed from the module when no longer referenced externally, effectively marking it as pending destruction. All new objects are unmanaged unless stated otherwise.

Parameters

value

The new value for the managed flag: true or false.

Returns

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

int OpenCMISS::Zinc::Glyph::setName ( const char *  name )

inline

Set name of the glyph.

Parameters

name	Name to be set for the glyph.

Returns

Status OpenCMISS::Zinc::OK on success, any other value on failure.
