Detailed Description

Class representing a general-purpose node an articulated scene graph.

Remarks:
A node in the scene graph is a node in a structured tree. A node contains information about the transformation which will apply to it and all of it's children. Child nodes can have transforms of their own, which are combined with their parent's transformations.

This is an abstract class - concrete classes are based on this for specific purposes, e.g. SceneNode, Bone

Matrix4 Ogre::Node::_getFullTransform void    const [virtual]
 

Gets the full transformation matrix for this node.

Remarks:
This method returns the full transformation matrix for this node, including the effect of any parent node transformations, provided they have been updated using the Node::_update method. This should only be called by a SceneManager which knows the derived transforms have been updated before calling this method. Applications using Ogre should just use the relative transforms.

void Ogre::Node::_update bool    updateChildren,
bool    parentHasChanged
[virtual]
 

Internal method to update the Node.

Note:
Updates this node and any relevant children to incorporate transforms etc. Don't call this yourself unless you are writing a SceneManager implementation.
Parameters:
updateChildren  If true, the update cascades down to all children. Specify false if you wish to update children separately, e.g. because of a more selective SceneManager implementation.
parentHasChanged  This flag indicates that the parent xform has changed, so the child should retrieve the parent's xform and combine it with its own even if it hasn't changed itself.

Reimplemented in Ogre::SceneNode, Ogre::TagPoint, and Ogre::BspSceneNode.

virtual void Ogre::Renderable::_updateCustomGpuParameter const GpuProgramParameters::AutoConstantEntry   constantEntry,
GpuProgramParameters   params
const [virtual, inherited]
 

Update a custom GpuProgramParameters constant which is derived from information only this Renderable knows.

Remarks:
This method allows a Renderable to map in a custom GPU program parameter based on it's own data. This is represented by a GPU auto parameter of ACT_CUSTOM, and to allow there to be more than one of these per Renderable, the 'data' field on the auto parameter will identify which parameter is being updated. The implementation of this method must identify the parameter being updated, and call a 'setConstant' method on the passed in GpuProgramParameters object, using the details provided in the incoming auto constant setting to identify the index at which to set the parameter.

You do not need to override this method if you're using the standard sets of data associated with the Renderable as provided by setCustomParameter and getCustomParameter. By default, the implementation will map from the value indexed by the 'constantEntry.data' parameter to a value previously set by setCustomParameter. But custom Renderables are free to override this if they want, in any case.

Parameters:
constantEntry  The auto constant entry referring to the parameter being updated
params  The parameters object which this method should call to set the updated parameters.

Reimplemented in Ogre::TerrainRenderable.

void Ogre::Node::_updateFromParent void    const [protected, virtual]
 

Triggers the node to update it's combined transforms.

This method is called internally by Ogre to ask the node to update it's complete transformation based on it's parents derived transform.

Reimplemented in Ogre::TagPoint.

void Ogre::Node::_weightedTransform Real    weight,
const Vector3   translate,
const Quaternion   rotate,
const Vector3   scale
[virtual]
 

Internal weighted transform method.

Remarks:
This method transforms a Node by a weighted amount from it's initial state. If weighted transforms have already been applied, the previous transforms and this one are blended together based on their relative weight. This method should not be used in combination with the unweighted rotate, translate etc methods.

Parameters:
translate  Initial translation offset of child relative to parent
rotate  Initial rotation relative to parent

References mChildren.

Referenced by Ogre::SceneNode::removeAndDestroyChild().

Node::ChildNodeIterator Ogre::Node::getChildIterator void    [virtual]
 

Retrieves an iterator for efficiently looping through all children of this node.

Remarks:
Using this is faster than repeatedly calling getChild if you want to go through all (or most of) the children of this node. Note that the returned iterator is only valid whilst no children are added or removed from this node. Thus you should not store this returned iterator for later use, nor should you add / remove children whilst iterating through it; store up changes for later. Note that calling methods on returned items in the iterator IS allowed and does not invalidate the iterator.

void Ogre::Node::scale Real    x,

Scales the node, combining it's current scale with the passed in scaling factor.

Remarks:
This method applies an extra scaling factor to the node's existing scale, (unlike setScale which overwrites it) combining it's current scale with the new one. E.g. calling this method twice with Vector3(2,2,2) would have the same effect as setScale(Vector3(4,4,4)) if the existing scale was 1.

Note that like rotations, scalings are oriented around the node's origin.

void Ogre::Renderable::setCustomParameter size_t    index,
const Vector4   value
[inherited]
 

Sets a custom parameter for this Renderable, which may be used to drive calculations for this specific Renderable, like GPU program parameters.

Remarks:
Calling this method simply associates a numeric index with a 4-dimensional value for this specific Renderable. This is most useful if the material which this Renderable uses a vertex or fragment program, and has an ACT_CUSTOM parameter entry. This parameter entry can refer to the index you specify as part of this call, thereby mapping a custom parameter for this renderable to a program parameter.
Parameters:
index  The index with which to associate the value. Note that this does not have to start at 0, and can include gaps. It also has no direct correlation with a GPU program parameter index - the mapping between the two is performed by the ACT_CUSTOM entry, if that is used.
value  The value to associate.

void Ogre::Node::setInheritScale bool    inherit [virtual]
 

Tells the node whether it should inherit scaling factors from it's parent node.

Remarks:
Scaling factors, unlike other transforms, are not always inherited by child nodes. Whether or not scalings affect both the size and position of the child nodes depends on the setInheritScale option of the child. In some cases you want a scaling factor of a parent node to apply to a child node (e.g. where the child node is a part of the same object, so you want it to be the same relative size and position based on the parent's size), but not in other cases (e.g. where the child node is just for positioning another object, you want it to maintain it's own size and relative position). The default is to inherit as with other transforms.
Parameters:
inherit  If true, this node's scale and position will be affected by its parent's scale. If false, it will not be affected.

void Ogre::Node::setInitialState void    [virtual]
 

Sets the current transform of this node to be the 'initial state' ie that position / orientation / scale to be used as a basis for delta values used in keyframe animation.

Remarks:
You never need to call this method unless you plan to animate this node. If you do plan to animate it, call this method once you've loaded the node with it's base state, ie the state on which all keyframes are based.

If you never call this method, the initial state is the identity transform, ie do nothing.

virtual bool Ogre::Renderable::useIdentityProjection void    const [virtual, inherited]
 

Returns whether or not to use an 'identity' projection.

Remarks:
Usually Renderable objects will use a projection matrix as determined by the active camera. However, if they want they can cancel this out and use an identity projection, which effectively projects in 2D using a {-1, 1} view space. Useful for overlay rendering. Normal renderables need not override this.
