Member Function Documentation

bool Lighting::LightPrePassServer::NeedsLightModelLinking (  )  const [inherited]

pre-light-pass doesn't require light/model linking

Indicate whether the light server requires visibility links between lights and models. Deferred lighting solutions usually don't need this. FIXME: EXCEPT for shadow map rendering!!

Reimplemented from Lighting::LightServerBase.

void Lighting::LightPrePassServer::RenderGlobalLight (  )  [protected, inherited]

render the global light

Render the global light as a fullscreen quad.

void Lighting::LightPrePassServer::RenderPointLights (  )  [protected, inherited]

render all point lights

Render point lights into the LightBuffer.

void Lighting::LightPrePassServer::AssignRenderBufferTextures (  )  [protected, inherited]

assign render buffers to shaders (one time init)

This does a one-time init of setting the NormalDepthBuffer and LightBuffer as shader variables.

void Lighting::LightServerBase::ApplyModelEntityLights ( const Ptr< InternalGraphics::InternalModelEntity > &  modelEntity  )  [inherited]

apply lighting parameters for a visible model entity

This method is called during rendering to apply lighting parameters to the provided ModelEntity.

Reimplemented in Lighting::SM30LightServer.

int Core::RefCounted::GetRefCount (  )  const [inline, inherited]

get the current refcount

Return the current refcount of the object.

void Core::RefCounted::AddRef (  )  [inline, inherited]

increment refcount by one

Increment the refcount of the object.

void Core::RefCounted::Release (  )  [inline, inherited]

decrement refcount and destroy object if refcount is zero

Decrement the refcount and destroy object if refcount is zero.

const Util::String & Core::RefCounted::GetClassName (  )  const [inline, inherited]

get the class name

Get the class name of the object.

Util::FourCC Core::RefCounted::GetClassFourCC (  )  const [inline, inherited]

get the class FourCC code

Get the class FourCC of the object.

void Core::RefCounted::DumpRefCountingLeaks (  )  [static, inherited]

dump refcounting leaks, call at end of application (NEBULA3_DEBUG builds only!)

This method should be called as the very last before an application exits.
