BasicLightManager Class Reference


isCompatible()

Checks to make sure that the graphics card is compatible with the current pixel shader version that is needed. Currently at least 1.0 is needed.



Syntax

isCompatible()

Returns

No return value.


Examples 
// Make sure its valid... else fail!
if ( !lm->isCompatible() )
    return false;

activate( SceneGraph *)

In addition to calling its base classes active(SceneGraph*), it will also set the Scenegraph to enable post effect fog and tell the material manager not to use prepass.



Syntax

activate( SceneGraph *sceneManager);
  • SceneGraph*: The SceneGraph to activate.

Returns
  • SceneGraph*: The activated SceneGraph object.

deactivate()

Will remove all the objects from the AdvancedLightBinManager and the PrePassRenderBin, then set them to NULL. It will deactivate the Shadow Manager, unregister all the advanced lighting features and then finally send a trigger to let everyone know the LightManager has been deactivated.



Syntax

deactivate()

Returns

No return value.


Examples 
if (mLightManager)
   mLightManager->deactivate();

setLightInfo( ProcessedMaterial *, const Material *, const SceneGraphData &, const SceneState *, U32, GFXShaderConstBuffer * )

Will make sure that the current lighting constants are initialized, then it will update the lighting constants via _update4LightConsts::_update4LightConsts.



Syntax

setLightInfo(ProcessedMaterial *pmat, Material *mat, const SceneGraphData &sgData, SceneState *state, U32 pass, GFXShaderConstBuffer *shaderConsts )
  • pmat: Not used.
  • mat: Not used.
  • sgData: Used in the call for _update4LightConsts. See LightManager::_update4LightConsts.
  • state: Not used.
  • pass: Not used.
  • shaderConsts: Is used to check to see if it is the same as the last shader. This check is done because T3D sorts by material and the light manager should get hit repeatedly by the same shader. The advantage of the check is that it gives optimization that will prevent has table look ups. It is also used in the call for _update4LightConsts. See LightManager::_update4LightConsts.

Returns

No return value.


Examples 
// From inside of ProcessedShaderMaterial::setSceneInfo
LIGHTMGR->setLightInfo( this, mMaterial, sgData, state, pass, shaderConsts );

setTextureStage( const SceneGraphData &sgData, const U32 currTexFlag, const U32 textureSlot, GFXShaderConstBuffer *shaderConsts, ShaderConstHandles *handles )

Will always return false.



Syntax

setTextureStage(const SceneGraphData &sgData, const U32 currTexFlag, const U32 textureSlot, GFXShaderConstBuffer *shaderConsts, ShaderConstHandles *handles )
  • sgData: Not used.
  • currTexFlag: Not used.
  • textureSlot: Not used
  • shaderConsts: Not used.
  • handles: Not used.

Returns

No return value.


Examples 
// From inside of ProcessedCustomMaterial::setTextureStages
lm->setTextureStage(sgData, currTexFlag, i, shaderConsts, handles )
