Detailed Description

GeoRenderItem - Geographically placed render item corresponding to a draw object.

This item contains viewport oriented graphics items for all the graphics relevant for one draw object. This may include both STK graphics primitives for text and vector graphics, as well as point symbol entries in the point symbol renderer.

The render items are created in pixel coordinates for the current viewport and a local affine transform is created during rendering to transform the item from the creation viewport to the current rendering viewport.

The render items are divided into two categories; Reusable and transient. Reusable items have a specific ID and can be retrieved for update when data changes. Transient items must re-generated each time the GeoRenderItem is updated.

Member Function Documentation

addRenderItem()

void Maria::GeoRenderItem::addRenderItem ( const std::shared_ptr< STK::RenderItem2D > &  renderItem, bool  declutter = false, bool  separateLabel = false  )

inline

Add a transient renderitem to the GeoRender. This item will not have a specific ID.

Parameters

renderItem	item to add
declutter	if the object should be decluttered
separateLabel	If the object should be handled separately during tile rendering.

clearTransientRenderItems()

void Maria::GeoRenderItem::clearTransientRenderItems ( )

inline

Clean out all transient render items.

getAllRenderItems()

std::vector< RenderItemInstance > Maria::GeoRenderItem::getAllRenderItems ( ) const

inline

Get all render item instances, both transient and reusable.

getGraphicsRenderItems()

int Maria::GeoRenderItem::getGraphicsRenderItems ( std::vector< std::shared_ptr< STK::RenderItem2D > > &  renderItems ) const

inline

Get all STK graphics render items, both transient and reusable.

getRenderItem()

std::shared_ptr< STK::RenderItem2D > Maria::GeoRenderItem::getRenderItem ( int  id )

inline

Get specific render item by ID

hasRenderItem()

bool Maria::GeoRenderItem::hasRenderItem ( int  id ) const

inline

Get if specific item (by ID) is in the set of reusable items.

Parameters

id

To Fetch

Returns

True if it exists in the set of reusableRenderItems

setRenderItem()

void Maria::GeoRenderItem::setRenderItem ( int  id, const std::shared_ptr< STK::RenderItem2D > &  renderItem, bool  declutter = false, bool  separateLabel = false  )

inline

Set reusable render item at a specific ID.

Parameters

renderItem	item to add
declutter	if the object should be decluttered
separateLabel	If the object should be handled separately during tile rendering.
