Detailed Description

ILightManager provides an interface for user applications to manipulate the list of lights in the scene.

The light list can be trimmed or re-ordered before device/ hardware lights are created, and/or individual lights can be switched on and off before or after each scene node is rendered. It is assumed that the ILightManager implementation will store any data that it wishes to retain, i.e. the ISceneManager to which it is assigned, the lightList, the current render pass, and the current scene node.

Member Function Documentation

OnNodePostRender()

virtual void irr::scene::ILightManager::OnNodePostRender ( ISceneNode *  node )

pure virtual

Called after the the node specified in OnNodePreRender() has been rendered.

Parameters

[in]

node

the scene node that has just been rendered

OnNodePreRender()

virtual void irr::scene::ILightManager::OnNodePreRender ( ISceneNode *  node )

pure virtual

Called before the given scene node is rendered.

Parameters

[in]

node

the scene node that's about to be rendered

OnPostRender()

virtual void irr::scene::ILightManager::OnPostRender ( void  )

pure virtual

Called after the last scene node is rendered.

After this call returns, the lightList passed to OnPreRender() becomes invalid.

OnPreRender()

virtual void irr::scene::ILightManager::OnPreRender ( core::array< ISceneNode * > &  lightList )

pure virtual

Called after the scene's light list has been built, but before rendering has begun.

As actual device/hardware lights are not created until the ESNRP_LIGHT render pass, this provides an opportunity for the light manager to trim or re-order the light list, before any device/hardware lights have actually been created.

Parameters

lightList

the Scene Manager's light list, which the light manager may modify. This reference will remain valid until OnPostRender().

OnRenderPassPostRender()

virtual void irr::scene::ILightManager::OnRenderPassPostRender ( E_SCENE_NODE_RENDER_PASS  renderPass )

pure virtual

Called after the render pass specified in OnRenderPassPreRender() ends.

Parameters

[in]

renderPass

the render pass that has finished

OnRenderPassPreRender()

virtual void irr::scene::ILightManager::OnRenderPassPreRender ( E_SCENE_NODE_RENDER_PASS  renderPass )

pure virtual

Called before a render pass begins.

Parameters

renderPass

the render pass that's about to begin
