Detailed Description

Module managing all glyphs.

Module managing all glyphs. Note that no glyphs exist on start-up, so most users will need to define standard glyphs early in their program, and after defining standard materials to pick up coloured standard glyphs.

Member Function Documentation

int OpenCMISS::Zinc::Glyphmodule::beginChange ( )
inline

Begin caching or increment cache level for this glyph module. Call this function before making multiple changes to minimise number of change messages sent to clients. Must remember to end_change after completing changes. Can be nested.

See Also
Glyphmodule::endChange
Returns
Status OpenCMISS::Zinc::OK on success, otherwise OpenCMISS::Zinc::ERROR_ARGUMENT.
GlyphAxes OpenCMISS::Zinc::Glyphmodule::createGlyphAxes ( const Glyph axisGlyph,
double  axisWidth 
)
inline

Create a glyph which drawing 3-D axes repeating the supplied axis glyph on three axes with the given axis width.

Parameters
axisGlyphA glyph to repeat on each of 3 axes.
axisWidthThe width of each axis glyph when drawn at unit length; a fraction of 1 to give an appropriate arrow head size. Typically 0.1 for glyph 'axis', 0.25 for glyph 'arrow_solid'. Must be non-negative.
Returns
Handle to new glyph, or NULL/invalid handle on failure.
GlyphColourBar OpenCMISS::Zinc::Glyphmodule::createGlyphColourBar ( const Spectrum spectrum)
inline

Create a glyph which draws a colour bar for the spectrum with ticks and value labels. The glyph dynamically updates to match the current range and definition of the spectrum. Note it only shows a single component.

Parameters
spectrumThe spectrum to be displayed on the colour bar.
Returns
Handle to new glyph, or NULL/invalid handle on failure.
int OpenCMISS::Zinc::Glyphmodule::defineStandardGlyphs ( )
inline

Defines a selection of standard glyphs for visualising points, vectors etc. Graphics for all standard glyphs fit in a unit cube which:

  1. for orientable glyphs e.g. line, arrow, cylinder: span [0,1] on axis 1, and [-0.5,0.5] on axes 2 and 3 (except line which has no width).
  2. are otherwise centred at 0,0,0 for all other glyphs. These consist of: "arrow", "arrow_solid" = line and solid arrows from (0,0,0) to (1,0,0) with arrowhead 1/3 of length and unit width. Shaft diameter is 1/3 unit. "axis", "axis_solid" = variants of arrows with arrowhead 1/10 of length. Shaft diameter is 1/3 unit. "cone", "cone_solid" = cone descending from unit diameter circle in 2-3 plane at (0,0,0) to a point at (1,0,0). Solid variant has base closed. "cross" = lines from -0.5 to +0.5 on each axis through (0,0,0). "cube_solid", "cube_wireframe" = solid and wireframe (line) unit cubes aligned with primary axes and centred at (0,0,0). "cylinder", "cylinder_solid" = a unit diameter cylinder, centre line from (0,0,0) to (1,0,0). Solid variant has ends closed. "diamond" = an octohedron created as a sphere with 4 divisions around, so lit like a sphere rather than faceted. "line" = a line from (0,0,0) to (1,0,0). "point" = a single pixel at (0,0,0). "sheet" = a unit square surface in 1-2 plane, centred at (0,0,0). "sphere" = a unit diameter sphere centred at (0,0,0). In addition there are 8 glyphs showing unit 3-D axes with various labels: "axes", "axes_123", "axes_xyz", "axes_colour" - using glyph "axis" and axis width 0.1. "axes_solid", "axes_solid_123", "axes_solid_xyz", "axes_solid_colour"
  • using glyph "arrow_solid" and axis width 0.25. Note that the colour axes find standard materials "red", "green" and "blue" for the 3 axes but are not created if those materials are not defined.
    See Also
    Materialmodule::defineStandardMaterials All the above standard glyphs also have unique types enumeration.
    Glyph::ShapeType
    Note if any glyphs of the predefined name already exist prior to calling this function, the standard glyph is not created. All glyphs created by this function have IS_MANAGED set to 1. Circular glyphs including sphere, cylinders, cones and solid arrow and axis get their circle divisions from the tessellation specified in the graphics. If not already set, the default glyph is set to "point" by this function.
Returns
OpenCMISS::Zinc::OK on success, otherwise OpenCMISS::Zinc::ERROR_ARGUMENT.
int OpenCMISS::Zinc::Glyphmodule::endChange ( )
inline

Decrement cache level or end caching of changes for the glyph module. Call glyphmodule begin change method before making multiple changes and call this afterwards. When change level is restored to zero, cached change messages are sent out to clients.

See Also
Glyphmodule::beginChange
Returns
Status OpenCMISS::Zinc::OK on success, any other value on failure.
Glyph OpenCMISS::Zinc::Glyphmodule::findGlyphByName ( const char *  name)
inline

Find the glyph with the specified name, if any.

Parameters
nameThe name of the glyph.
Returns
Handle to glyph, or NULL/invalid handle if not found or failed.
Glyph OpenCMISS::Zinc::Glyphmodule::getDefaultPointGlyph ( )
inline

Get the default glyph used for new point graphics, if any.

Returns
Handle to glyph, or NULL/invalid handle if none or failed.
cmzn_glyphmodule_id OpenCMISS::Zinc::Glyphmodule::getId ( ) const
inline

Return the C handle of the Glyphmodule object.

Returns
C handle of Glyphmodule if this objects is valid, 0 otherwise.
bool OpenCMISS::Zinc::Glyphmodule::isValid ( ) const
inline

Check if this is a valid Glyphmodule object.

Returns
Status True if object is valid, false otherwise.
int OpenCMISS::Zinc::Glyphmodule::setDefaultPointGlyph ( const Glyph glyph)
inline

Set the default glyph used for new point graphics.

Parameters
glyphThe glyph to set as default.
Returns
OpenCMISS::Zinc::OK on success otherwise OpenCMISS::Zinc::ERROR_ARGUMENT.
