Member Function Documentation

const Matrix4& Ogre::Bone::_getBindingPoseInverseTransform ( void ) const

Gets the inverse transform which takes bone space to origin from the binding pose.

Remarks:
Internal use only.

virtual const Quaternion& Ogre::Node::_getDerivedOrientation ( void ) const [virtual, inherited]

Gets the orientation of the node as derived from all parents.

virtual const Vector3& Ogre::Node::_getDerivedPosition ( void ) const [virtual, inherited]

Gets the position of the node as derived from all parents.

virtual const Vector3& Ogre::Node::_getDerivedScale ( void ) const [virtual, inherited]

Gets the scaling factor of the node as derived from all parents.

virtual Matrix4 Ogre::Node::_getFullTransform ( void ) const [virtual, inherited]

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.

virtual void Ogre::Node::_update ( bool updateChildren,

bool parentHasChanged

) [virtual, inherited]

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.
Definition at line 219 of file OgreRenderable.h.
References Ogre::GpuProgramParameters::AutoConstantEntry::data, Ogre::GpuProgramParameters::AutoConstantEntry::index, and params.

virtual void Ogre::Node::_updateFromParent ( void ) const [protected, virtual, inherited]

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.

virtual void Ogre::Node::_weightedTransform ( Real weight,

const Vector3 & translate,

const Quaternion & rotate,

const Vector3 & scale

) [virtual, inherited]

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.

virtual void Ogre::Node::addChild ( Node * child ) [virtual, inherited]

Adds a (precreated) child scene node to this node.
If it is attached to another node, it must be detached first.
Parameters:

child The Node which is to become a child node of this one

virtual void Ogre::Node::cancelUpdate ( Node * child ) [virtual, inherited]

Called by children to notify their parent that they no longer need an update.

virtual Node* Ogre::Node::createChild ( const String & name,

const Vector3 & translate = Vector3::ZERO,

const Quaternion & rotate = Quaternion::IDENTITY

) [virtual, inherited]

Creates a new named Node as a child of this node.

Remarks:
This creates a child node with a given name, which allows you to look the node up from the parent which holds this collection of nodes.

Parameters:

translate Initial translation offset of child relative to parent

rotate Initial rotation relative to parent

virtual Node* Ogre::Node::createChild ( const Vector3 & translate = Vector3::ZERO,

const Quaternion & rotate = Quaternion::IDENTITY

) [virtual, inherited]

Remarks:
This method creates a new bone which will inherit the transforms of this bone, with the handle specified.

Parameters:

Definition at line 154 of file OgreRenderable.h.

virtual Node* Ogre::Node::getChild ( const String & name ) const [virtual, inherited]

virtual Node* Ogre::Node::getChild ( unsigned short index ) const [virtual, inherited]

Gets a pointer to a child node.

Remarks:
There is an alternate getChild method which returns a named child.

virtual ConstChildNodeIterator Ogre::Node::getChildIterator ( void ) const [virtual, inherited]

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.

virtual ChildNodeIterator Ogre::Node::getChildIterator ( void ) [virtual, inherited]

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.

virtual unsigned short Ogre::Renderable::getNumWorldTransforms ( void ) const [virtual, inherited]

Returns the number of world transform matrices this renderable requires.

Remarks:
When a renderable uses vertex blending, it uses multiple world matrices instead of a single one. Each vertex sent to the pipeline can reference one or more matrices in this list with given weights. If a renderable does not use vertex blending this method returns 1, which is the default for simplicity.

Reimplemented in Ogre::BorderRenderable, and Ogre::SubEntity.
Definition at line 104 of file OgreRenderable.h.

Bones are bound to the mesh in a binding pose. They are then modified from this position during animation. This method returns the bone to it's original position and orientation.

virtual void Ogre::Node::resetOrientation ( void ) [virtual, inherited]

Resets the nodes orientation (local axes as world axes, no rotation).

virtual void Ogre::Node::resetToInitialState ( void ) [virtual, inherited]

Resets the position / orientation / scale of this node to it's initial state, see setInitialState for more info.

virtual void Ogre::Node::roll ( const Radian & angle,

TransformSpace relativeTo = TS_LOCAL

) [virtual, inherited]

Rotate the node around the Z-axis.

virtual void Ogre::Node::rotate ( const Quaternion & q,

TransformSpace relativeTo = TS_LOCAL

) [virtual, inherited]

Rotate the node around an aritrary axis using a Quarternion.

virtual void Ogre::Node::rotate ( const Vector3 & axis,

const Radian & angle,

TransformSpace relativeTo = TS_LOCAL

) [virtual, inherited]

Rotate the node around an arbitrary axis.

virtual void Ogre::Node::scale ( Real x,

Real y,

Real z

) [virtual, inherited]

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.

virtual void Ogre::Node::scale ( const Vector3 & scale ) [virtual, inherited]

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::Bone::setBindingPose ( void )

Sets the current position / orientation to be the 'binding pose' ie the layout in which bones were originally bound to a mesh.

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.

virtual void Ogre::Node::setInheritScale ( bool inherit ) [virtual, inherited]

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.

virtual void Ogre::Node::setInitialState ( void ) [virtual, inherited]

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.

void Ogre::Bone::setManuallyControlled ( bool manuallyControlled )

Sets whether or not this bone is manually controlled.

Remarks:
Manually controlled bones can be altered by the application at runtime, and their positions will not be reset by the animation routines. Note that you should also make sure that there are no AnimationTrack objects referencing this bone, or if there are, you should disable them using pAnimation->destroyTrack(pBone->getHandle());

virtual void Ogre::Node::setOrientation ( Real w,

Real x,

Real y,

Real z

) [virtual, inherited]

Sets the orientation of this node via quaternion parameters.

virtual void Ogre::Node::setOrientation ( const Quaternion & q ) [virtual, inherited]

Sets the orientation of this node via a quaternion.

virtual void Ogre::Node::setParent ( Node * parent ) [protected, virtual, inherited]

Only available internally - notification of parent.

Reimplemented in Ogre::SceneNode.

virtual void Ogre::Node::setPosition ( Real x,

Real y,

Real z

) [virtual, inherited]

Sets the position of the node relative to it's parent.

virtual void Ogre::Node::setPosition ( const Vector3 & pos ) [virtual, inherited]

Sets the position of the node relative to it's parent.

virtual void Ogre::Renderable::setRenderDetailOverrideable ( bool override ) [virtual, inherited]

Sets whether this renderable's chosen detail level can be overridden (downgraded) by the camera setting.

Parameters:

override true means that a lower camera detail will override this renderables detail level, false means it won't.

Definition at line 235 of file OgreRenderable.h.

virtual void Ogre::Node::setScale ( Real x,

Real y,

Real z

) [virtual, inherited]

Sets the scaling factor applied to this 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.

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

virtual void Ogre::Node::setScale ( const Vector3 & scale ) [virtual, inherited]

Sets the scaling factor applied to this node.

Remarks:
Scaling factors, unlike other transforms, are not always inherited by child nodes.

virtual void Ogre::Node::translate ( const Matrix3 & axes,

Real x,

Real y,

Real z,

TransformSpace relativeTo = TS_PARENT

) [virtual, inherited]

Moves the node along arbitrary axes.

Remarks:
This method translates the node by a vector which is relative to a custom set of axes.

Parameters:

axes A 3x3 Matrix containg 3 column vectors each representing the axes X, Y and Z respectively. In this format the standard cartesian axes would be expressed as
1 0 0 0 1 0 0 0 1
i.e. the identity matrix.

x,y,z Translation components relative to the axes above.

relativeTo The space which this transform is relative to.

virtual void Ogre::Node::translate ( const Matrix3 & axes,

const Vector3 & move,

TransformSpace relativeTo = TS_PARENT

) [virtual, inherited]

Moves the node along arbitrary axes.

Remarks:
This method translates the node by a vector which is relative to a custom set of axes.

Parameters:

axes A 3x3 Matrix containg 3 column vectors each representing the axes X, Y and Z respectively. In this format the standard cartesian axes would be expressed as:
1 0 0 0 1 0 0 0 1
i.e. the identity matrix.

move Vector relative to the axes above.

relativeTo The space which this transform is relative to.

virtual void Ogre::Node::translate ( Real x,

Real y,

Real z,

TransformSpace relativeTo = TS_PARENT

) [virtual, inherited]

Moves the node along the cartesian axes.

This method moves the node by the supplied vector along the world cartesian axes, i.e. along world x,y,z

Parameters:

x

y

z Real x, y and z values representing the translation.

relativeTo The space which this transform is relative to.

virtual void Ogre::Node::translate ( const Vector3 & d,

TransformSpace relativeTo = TS_PARENT

) [virtual, inherited]

Moves the node along the cartesian axes.

This method moves the node by the supplied vector along the world cartesian axes, i.e. along world x,y,z

Parameters:

d Vector with x,y,z values representing the translation.

relativeTo The space which this transform is relative to.

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.

Reimplemented in Ogre::BorderRenderable, Ogre::OverlayElement, and Ogre::Rectangle2D.
Definition at line 114 of file OgreRenderable.h.

virtual bool Ogre::Renderable::useIdentityView ( void ) const [virtual, inherited]

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

Remarks:
Usually Renderable objects will use a view matrix as determined by the active camera. However, if they want they can cancel this out and use an identity matrix, which means all geometry is assumed to be relative to camera space already. Useful for overlay rendering. Normal renderables need not override this.

Reimplemented in Ogre::BorderRenderable, Ogre::OverlayElement, and Ogre::Rectangle2D.
Definition at line 124 of file OgreRenderable.h.

virtual void Ogre::Node::yaw ( const Radian & angle,

TransformSpace relativeTo = TS_LOCAL

) [virtual, inherited]
