calcGlobalNodeData()

template<Strategy strategy>

bool QSSGRenderDataHelpers::calcGlobalNodeData ( QSSGRenderNode * node, const VersionType version, QSSGGlobalRenderNodeData::GlobalTransformStore & globalTransforms, QSSGGlobalRenderNodeData::GlobalOpacityStore & globalOpacities )

inlinestatic

calcGlobalNodeData

Parameters

node	The node to calculate the global data for.
version	The version of the node current node tree.
globalTransforms	The global transforms store.
globalOpacities	The global opacities store.

Returns

true if the data was updated, false otherwise.

The function is used to calculate the global node data for the given node. It will use the given strategy to determine if it should calculate the initial values or update the existing values based on the node's dirty state.

NOTE: This function assumes the output data is already allocated and can be directly indexed!!!

calcInstanceTransforms()

bool QSSGRenderDataHelpers::calcInstanceTransforms ( QSSGRenderNode * node, const VersionType version, QSSGGlobalRenderNodeData::GlobalTransformStore & globalTransforms, QSSGGlobalRenderNodeData::InstanceTransformStore & instanceTransforms )

static

calcInstanceTransforms

Parameters

node	The node to calculate the instance transforms for.
version	The version of the node current node tree.
globalTransforms	The global transforms store.
instanceTransforms	The instance transforms store.

Returns

true if the data was updated, false otherwise.

The function is used to calculate the instance transforms for the given node.

NOTE: This function assumes the output data is already allocated and can be directly indexed!!!

updateGlobalNodeState()

QSSGRenderDataHelpers::GlobalStateResult QSSGRenderDataHelpers::updateGlobalNodeState ( QSSGRenderNode * node, const VersionType version )

static

updateGlobalNodeState

Parameters

node	The node to update the global state for.
version	The version of the node current node tree.

Returns

The result of the update.

The function is used to update the global state flagsfor the given node, meaning the global active and pickable state of the node.
