Member Function Documentation
| void Models::StateNode::AddShaderParam | ( | const Util::String & | paramName, | |
| const Util::Variant & | paramValue | |||
| ) | [inherited] |
add optional shader parameter, must be called before LoadResources
Manual shaderparameters must be added before LoadResources is called, because on LoadResources all shaderparams are validated.
| void Models::StateNode::SetupManagedTextureVariable | ( | const Resources::ResourceId & | texResId, | |
| const Ptr< CoreGraphics::ShaderVariable > & | var | |||
| ) | [protected, inherited] |
setup a new managed texture variable
Create a new managed texture resource and bind it to the provided shader variable.
| void Models::StateNode::UpdateManagedTextureVariables | ( | IndexT | frameIndex | ) | [protected, inherited] |
update managed texture variables
This method transfers texture from our managed texture objects into their associated shader variable. This is necessary since the actual texture of a managed texture may change from frame to frame because of resource management.
| Ptr< ModelNodeInstance > Models::ModelNode::CreateNodeInstanceHierarchy | ( | const Ptr< ModelInstance > & | modelInst | ) | [inherited] |
recursively create model node instance and child model node instances
Create the node instance hierarchy.
| void Models::ModelNode::BeginParseDataTags | ( | ) | [virtual, inherited] |
begin parsing data tags
Begin parsing data tags. This method is called by StreamModelLoader before ParseDataTag() is called for the first time.
| void Models::ModelNode::EndParseDataTags | ( | ) | [virtual, inherited] |
finish parsing data tags
End parsing data tags. This method is called by StreamModelLoader after the last ParseDataTag() is called.
| void Models::ModelNode::ResetScreenSpaceStats | ( | ) | [inline, inherited] |
resets all screen space stats e.g. size
Reset resourceStreamingLevelOfDetail to -1.0 as we are able to recognize invisible items this way. (visible items will overwrite this value with a value >= 0.0)
| Ptr< ModelNodeInstance > Models::ModelNode::RecurseCreateNodeInstanceHierarchy | ( | const Ptr< ModelInstance > & | modelInst, | |
| const Ptr< ModelNodeInstance > & | parentNodeInst | |||
| ) | [protected, virtual, inherited] |
recursively create node instance hierarchy
Recursively create node instances and attach them to the provided model instance. Returns a pointer to the root node instance.
| 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.
