Detailed Description

GAS tree for raytracing UV maps.

Member Function Documentation

bool GasUvTree::is_dirty ( ) const

inline

Returns the dirty state of the GasUvTree. If dirty it needs to be rebuilt.

Returns: true if dirty, false otherwise

bool GasUvTree::is_empty ( ) const

Returns the empty state. The GasUvTree is empty if there is no geometry data and no edge data.

Returns: true if empty, false otherwise.

void GasUvTree::update	(	AppBase &	app,
		const CoreSet< OfObject * > &	geometries,
		bool	use_first_uv_map,
		const CoreString &	uv_map_name
	)

Updates the data needed to build the GasUvTree and marks it as dirty.

The parameters are used by the method build() to actually load and build the GasUvTree.

Parameters

app	The application.
geometries	List of geometries for which their UV maps will be used.
use_first_uv_map	If true, the GasUvTree will use the first UV map of each geometry in the list.
uv_map_name	The UV map name to use for each geometry from the list. This parameter is ignored if use_first_uv_map is true. If a geometry doesn't have any UV map matching the name, the geometry is ignored.
