Class Detail
threedee.SceneNode()
Method Detail
addUpdater(updater)
Adds the specified node updater to this node.
Parameters:
{!threedee.NodeUpdater} updater
The updater to add

appendChild(node)
Appends the specified node as a child node to this node. If the node was previously connected to a different parent node then it is first disconnected from this parent.
Parameters:
{!threedee.SceneNode} node
The node to append to this node

{!threedee.Matrix} getEffectiveTransform()
Returns the effective transformation of this node by recursively traversing the path up the root node and multiplying all found transformations. Depending on the complexity of your scene graph this is time-consuming so thing twice if you really need it.
Returns:
{!threedee.Matrix} The effective transformation.

{?threedee.SceneNode} getFirstChild()
Returns the first child node of this node. If the node has no child nodes then null is returned.
Returns:
{?threedee.SceneNode} The first child node or null if there are no child nodes

{?threedee.SceneNode} getLastChild()
Returns the last child node of this node. If the node has no child nodes then null is returned.
Returns:
{?threedee.SceneNode} The last child node or null if there are no child nodes

{?threedee.SceneNode} getNextSibling()
Returns the next sibling of this node. If the node is the last child node of its parent then null is returned because there can't be a next sibling.
Returns:
{?threedee.SceneNode} The next sibling of this node or null if there is no next sibling

{?threedee.SceneNode} getParentNode()
Returns the parent node. If the node has no root node yet then null is returned.
Returns:
{?threedee.SceneNode} The parent node or null if there is none

{?threedee.SceneNode} getPreviousSibling()
Returns the previous sibling of this node. If the node is the first child node of its parent then null is returned because there can't be a previous sibling.
Returns:
{?threedee.SceneNode} The previous sibling of this node or null if there is no previous sibling

{!threedee.Matrix} getTransform()
Returns the current transformation matrix.
Returns:
{!threedee.Matrix} The current transformation matrix

{boolean} hasChildNodes()
Checks if this node has child nodes.
Returns:
{boolean} True if this node has child nodes, false if not

insertBefore(insertNode, referenceNode)
Inserts a new child node before the specified reference node. If the new node was already connected to a parent then it is disconnected from this parent first.
Parameters:
{!threedee.SceneNode} insertNode
The new node to insert.
{!threedee.SceneNode} referenceNode
The reference node.

removeChild(node)
Removes the specified child node from this node.
Parameters:
{!threedee.SceneNode} node
The node to remove

removeUpdater(updater)
Removes the specified node updater from this node.
Parameters:
{!threedee.NodeUpdater} updater
The updater to remove

render(buffer, transform)
Renders the node. Default implementation is doing nothing except calling the render method of all child nodes.
Parameters:
{!threedee.PolygonBuffer} buffer
The polygon buffer
{!threedee.Matrix} transform
The current transformation

replaceChild(oldNode, newNode)
Replaces the specified old node with the specified new node. If the new node was already connected to a parent then it is disconnected from this parent first.
Parameters:
{!threedee.SceneNode} oldNode
The old node to be replaced by the new one
{!threedee.SceneNode} newNode
The new node to replace the old one

setTransform(transform)
Sets the transformation matrix.
Parameters:
{!threedee.Matrix} transform
The transformation matrix to set

update(delta)
Updates the node with the specified time delta. Default implementation is executing the connected node updaters and calling the update method of all child nodes.
Parameters:
{number} delta
The time elapsed since the last scene update (in nanoseconds)
