// Class : DirectRenderTransition
|
|
// Description : When this transition is attached to an arc, it
|
|
// indicates that the node below this arc, and all
|
|
// subsequent nodes below, should be treated as a single
|
|
// binnable unit. All the nodes at this point and below
|
|
// will be placed into the same bin, according to the
|
|
// state as of the top node, and when rendered, they
|
|
// will be rendered using a depth-first traversal rooted
|
|
// at this top node.
|
|
//
|
|
// This can be a way to establish a local draw-order
|
|
// within a few related nodes. It does not, however,
|
|
// affect view-frustum culling.
|
|
//
|
|
// This is the only way to achieve certain special
|
|
// effects that depend on scene-graph relationships, for
|
|
// instance decalling, while using the CullTraverser.
