Detailed Description

The context is the primary object created for each instance of Zinc.

The context is the primary object created for each instance of Zinc. All other objects are created or obtained directly or indirectly from it. If multiple contexts are used, ensure that only objects stemming from the same context are used together.

Member Function Documentation

Region OpenCMISS::Zinc::Context::createRegion ( )

inline

Create a new region and return a handle to it. Use this function to create a region forming the root of an independent region tree. Equivalent to region create region method. Compare with region create child/subregion methods which create and add a region to the tree.

See Also: Region::createRegion; Region::createChild; Region::createSubregion

Returns: Handle to new region, or NULL/invalid handle on failure.

Region OpenCMISS::Zinc::Context::getDefaultRegion ( )

inline

Returns the default region in the context.

Returns: Handle to region, or NULL/invalid handle on failure.

Fontmodule OpenCMISS::Zinc::Context::getFontmodule ( )

inline

Get the font module which manages fonts for rendering text in graphics.

Returns: Handle to the font module, or NULL/invalid handle on failure.

Glyphmodule OpenCMISS::Zinc::Context::getGlyphmodule ( )

inline

Get the glyph module which stores static graphics for visualising points, vectors, axes etc. Note on startup no glyphs are defined and glyph module functions need to be called to define standard glyphs.

Returns: Handle to the glyph module, or NULL/invalid handle on failure.

cmzn_context_id OpenCMISS::Zinc::Context::getId ( ) const

inline

Return the C handle of the Context object.

Returns: C handle of Context if this objects is valid, 0 otherwise.

Materialmodule OpenCMISS::Zinc::Context::getMaterialmodule ( )

inline

Return the material module which manages materials used to colour, texture and shade graphics. Note on startup only materials "default" and "default_selected" are defined, as white and red, respectively. Additional standard and custom materials can be defined using material module functions.

Returns: Handle to the material module, or NULL/invalid handle on failure.

int OpenCMISS::Zinc::Context::getRevision ( )

inline

Get the revision number of this Zinc library.

Returns: Revision of this Zinc library on success, 0 on failure.

Scenefiltermodule OpenCMISS::Zinc::Context::getScenefiltermodule ( )

inline

Get the scene filter module which manages scenefilter objects for filtering contents of scenes with scenepicker and sceneviewer etc.

Returns: Handle to the scene filter module, or NULL/invalid handle on failure.

Sceneviewermodule OpenCMISS::Zinc::Context::getSceneviewermodule ( )

inline

Returns a handle to a sceneviewer module which manages sceneviewer objects for rendering 3-D scenes into rectangular windows or canvases using OpenGL.

Returns: Handle to the sceneviewer module, or NULL/invalid handle on failure.

Spectrummodule OpenCMISS::Zinc::Context::getSpectrummodule ( )

inline

Get the spectrum module which manages spectrum objects controlling how graphics data fields are converted into colours.

Returns: Handle to the spectrum module, or NULL/invalid handle on failure.

Tessellationmodule OpenCMISS::Zinc::Context::getTessellationmodule ( )

inline

Get the tessellation module which manages objects controlling how curves are approximated by line segments in graphics.

Returns: Handle to the tesselation module, or NULL/invalid handle on failure.

Timekeepermodule OpenCMISS::Zinc::Context::getTimekeepermodule ( )

inline

Get the timekeeper module which manages objects for synchronising time across zinc objects.

Returns: Handle to the timekeeper module, or NULL/invalid handle on failure.

int OpenCMISS::Zinc::Context::getVersion ( int * versionOut3 )

inline

Get the version number of this Zinc library. It will return the major version, minor version and patch version in a 3 component integer array.

Parameters

versionOut3 Array of size 3 to hold the values of the version number, they are the major version, minor version and patch version respectively.

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

char* OpenCMISS::Zinc::Context::getVersionString ( )

inline

Get the version string of this Zinc library. The version string will be output in the following format "[major version].[minor version].[patch version].r[revision(M)](.Debug)" (M) indicates this binary contains local modifications that are not included in the revision, and (.Debug) indicates this binary is not optimised.

Returns: on success : allocated string containing version details. Up to caller to free using cmzn_deallocate().

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

inline

Check if this is a valid Context object.

Returns: Status True if object is valid, false otherwise.
