Member Function Documentation

unsigned DD::Image::GeometryList::objects

(

)

const [inline]

Current object count.

unsigned DD::Image::GeometryList::offset

(

)

const [inline]

Absolute starting index in output list.

GeoOp* DD::Image::GeometryList::geo

(

)

const [inline]

The GeoOp that is currently manipulating this cache.

Referenced by DD::Image::GeoOp::get_geometry().

unsigned DD::Image::GeometryList::size

(

)

const [inline]

Object count. Duplicate call to object() for convenience.

Referenced by DD::Image::Render::_request(), DD::Image::Scene::generate_render_primitives(), DD::Image::TransformGeo::geometry_engine(), DD::Image::ReadGeo::geometry_engine(), DD::Image::ModifyGeo::geometry_engine(), DD::Image::GeoOp::get_geometry(), DD::Image::SourceGeo::init_geoinfo_parms(), DD::Image::GeoOp::print_info(), DD::Image::GeoOp::setupScene(), and DD::Image::Scene::validate().

void GeometryList::add_object

(

int

obj

)

Add a GeoInfo to the cache.

void GeometryList::delete_objects

(

)

Delete all allocated geometry and clear the cache and output list of objects.

References DD::Image::GeoOp::delete_cache(), and DD::Image::GeoOp::objects_.

Referenced by DD::Image::ReadGeo::create_geometry().

void GeometryList::synchronize_objects

(

)

Synchronize the local cache object list with the current object list. Calling this repeatedly is cheap as it returns quickly if the cache's build_hash already matches the geo's build hash.

int GeometryList::add_primitive	(	int	obj,
		Primitive *	p = 0
	)

Create a local primitive allocation and append a primitive to it if p is non-NULL. Returns the current size of the list.

Return a local writable primitive by index.
