Member Function Documentation

begin()

bool GEO::MeshGfx::Filter::begin	(	AttributesManager &	attributes_manager,
		bool	hw_primitive_filtering = true
	)

Begins rendering with primitive filtering.

Parameters

[in]	attributes_manager	a reference to the attributes manager where the property is stored
[in]	hw_primitive_filtering	if set, uses hardware primitive fitering (GLUP_PRIMITIVES_FILTERING), else one may use the function test() instead.

Return values

true	if attribute filtering is active, that is, if attribute name is not the empty string and if an the attribute exists
false	otherwise

test()

bool GEO::MeshGfx::Filter::test ( index_t  primitive_id ) const

inline

Tests an individual primitive.

Return values

true	if the primitive should be displayed
false	otherwise
