Detailed Description

Cache for storing the 3D shapes.

This cache is able to be stored as a project element (since it inherits from PROJECT::_ELEM).

Member Function Documentation

◆ checkCache()

SCENEGRAPH * S3D_CACHE::checkCache	(	const wxString &	aFileName,
		S3D_CACHE_ENTRY **	aCachePtr = `nullptr`
	)

private

Find or create cache entry for file name.

Searches the cache list for the given filename and retrieves the cache data; a cache entry is created if one does not already exist.

Parameters

aFileName	is the file name (full or partial path).
aCachePtr	is an optional return address for cache entry pointer.

Returns: SCENEGRAPH object associated with file name or NULL on error.

Parameters

aNumDaysOld is age threshold to delete ".3dc" cache files.

Referenced by ~S3D_CACHE().

◆ GetFileFilters()

std::list< wxString > const * S3D_CACHE::GetFileFilters ( ) const

Return the list of file filters retrieved from the plugins.

This will contain at least the default "All Files (*.*)|*.*"

Returns: a pointer to the filter list.

◆ GetModel()

S3DMODEL * S3D_CACHE::GetModel	(	const wxString &	aModelFileName,
		const wxString &	aBasePath
	)

Attempt to load the scene data for a model and to translate it into an S3D_MODEL structure for display by a renderer.

Parameters

aModelFileName is the full path to the model to be loaded.

Returns: is a pointer to the render data or NULL if not available.

◆ getSHA1()

bool S3D_CACHE::getSHA1	(	const wxString &	aFileName,
		unsigned char *	aSHA1Sum
	)

private

Calculate the SHA1 hash of the given file.

Parameters

aFileName	file name (full path).
aSHA1Sum	a 20 byte character array to hold the SHA1 hash.

Returns: true on success, otherwise false.

◆ Load()

SCENEGRAPH * S3D_CACHE::Load	(	const wxString &	aModelFile,
		const wxString &	aBasePath
	)

Attempt to load the scene data for a model.

It will consult the internal cache list and load from cache if possible before invoking the load() function of the available plugins. The model may fail to load if, for example, the plugin does not support rendering of the 3D model.

Parameters

aModelFile	is the partial or full path to the model to be loaded.
aBasePath	is the path to search for any relative files

Returns: true if the model was successfully loaded, otherwise false.
