Detailed Description

Definition of a Plane that may be attached to a node, and the derived details of it retrieved simply.

Remarks:: This plane is not here for rendering purposes, it's to allow you to attach planes to the scene in order to have them move and follow nodes on their own, which is useful if you're using the plane for some kind of calculation, e.g. reflection.

virtual void Ogre::ShadowCaster::extrudeBounds ( AxisAlignedBox & box,

const Vector4 & lightPos,

Real extrudeDist

) const [protected, virtual, inherited]

Utility method for extruding a bounding box.

Parameters:

box Original bounding box, will be updated in-place

lightPos 4D light position in object space, when w=0.0f this represents a directional light

extrudeDist The distance to extrude

void Ogre::ShadowCaster::extrudeVertices ( HardwareVertexBufferSharedPtr vertexBuffer,

size_t originalVertexCount,

const Vector4 & lightPos,

Real extrudeDist

) [static, inherited]

Utility method for extruding vertices based on a light.

Remarks:
Unfortunately, because D3D cannot handle homogenous (4D) position coordinates in the fixed-function pipeline (GL can, but we have to be cross-API), when we extrude in software we cannot extrude to infinity the way we do in the vertex program (by setting w to 0.0f). Therefore we extrude by a fixed distance, which may cause some problems with larger scenes. Luckily better hardware (ie vertex programs) can fix this.

Parameters:

vertexBuffer The vertex buffer containing ONLY xyz position values, which must be originalVertexCount * 2 * 3 floats long.

originalVertexCount The count of the original number of vertices, ie the number in the mesh, not counting the doubling which has already been done (by VertexData::prepareForShadowVolume) to provide the extruded area of the buffer.

lightPos 4D light position in object space, when w=0.0f this represents a directional light

extrudeDist The distance to extrude

virtual void Ogre::ShadowCaster::generateShadowVolume ( EdgeData * edgeData,

HardwareIndexBufferSharedPtr indexBuffer,

const Light * light,

ShadowRenderableList & shadowRenderables,

unsigned long flags

) [protected, virtual, inherited]

Generates the indexes required to render a shadow volume into the index buffer which is passed in, and updates shadow renderables to use it.

Parameters:

edgeData The edge information to use

indexBuffer The buffer into which to write data into; current contents are assumed to be discardable.

light The light, mainly for type info as silhouette calculations should already have been done in updateEdgeListLightFacing

shadowRenderables A list of shadow renderables which has already been constructed but will need populating with details of the index ranges to be used.

flags Additional controller flags, see ShadowRenderableFlags

virtual const String& Ogre::AnimableObject::getAnimableDictionaryName ( void ) const [protected, virtual, inherited]

Real Ogre::Plane::getDistance ( const Vector3 & rkPoint ) const [inherited]

This is a pseudodistance.
The sign of the return value is positive if the point is on the positive side of the plane, negative if the point is on the negative side, and zero if the point is on the plane.

Definition at line 114 of file OgreMovableObject.h.
References Ogre::String.

virtual Node* Ogre::MovableObject::getParentNode ( void ) const [virtual, inherited]

Returns the node to which this object is attached.

Remarks:
A MovableObject may be attached to either a SceneNode or to a TagPoint, the latter case if it's attached to a bone on an animated entity. Both are Node subclasses so this method will return either.

virtual SceneNode* Ogre::MovableObject::getParentSceneNode ( void ) const [virtual, inherited]

Returns the scene node to which this object is attached.

Remarks:
A MovableObject may be attached to either a SceneNode or to a TagPoint, the latter case if it's attached to a bone on an animated entity. This method will return the scene node of the parent entity if the latter is true.

Referenced by Ogre::PlaneBoundedVolume::intersects().

virtual uint32 Ogre::MovableObject::getTypeFlags ( void ) const [virtual, inherited]

Get the 'type flags' for this MovableObject.

Remarks:
A type flag identifies the type of the MovableObject as a bitpattern. This is used for categorical inclusion / exclusion in SceneQuery objects. By default, this method returns all ones for objects not created by a MovableObjectFactory (hence always including them); otherwise it returns the value assigned to the MovableObjectFactory. Custom objects which don't use MovableObjectFactory will need to override this if they want to be included in queries.

Reimplemented in Ogre::BillboardSet, Ogre::Entity, Ogre::Light, Ogre::ParticleSystem, Ogre::StaticGeometry::Region, and Ogre::TerrainRenderable.

Reimplemented in Ogre::Entity.

virtual const Sphere& Ogre::MovableObject::getWorldBoundingSphere ( bool derive = false ) const [virtual, inherited]

Retrieves the worldspace bounding sphere for this object.

Reimplemented in Ogre::Entity.

virtual void Ogre::AnimableObject::initialiseAnimableDictionary ( StringVector & vec ) const [protected, virtual, inherited]

Internal method for initialising dictionary; should be implemented by subclasses wanting to expose animable parameters.

Reimplemented in Ogre::Light.
Definition at line 248 of file OgreAnimable.h.
References Ogre::StringVector.

virtual bool Ogre::MovableObject::isAttached ( void ) const [virtual, inherited]

Returns whether or not this object is supposed to be visible or not.

Remarks:
Takes into account both upper rendering distance and visible flag.

Reimplemented in Ogre::StaticGeometry::Region.

bool Ogre::Plane::operator== ( const Plane & rhs ) const [inherited]

Comparison operator.

Definition at line 101 of file OgrePlane.h.
References Ogre::Plane::d, and Ogre::Plane::normal.

Vector3 Ogre::Plane::projectVector ( const Vector3 & v ) [inherited]

Project a vector onto the plane.

Remarks:
This gives you the element of the input vector that is perpendicular to the normal of the plane. You can get the element which is parallel to the normal of the plane by subtracting the result of this method from the original vector, since parallel + perpendicular = original.

Parameters:

v The input vector

void Ogre::Plane::redefine ( const Vector3 & rkPoint0,

const Vector3 & rkPoint1,

const Vector3 & rkPoint2

) [inherited]

Redefine this plane based on 3 points.

virtual void Ogre::MovableObject::removeQueryFlags ( unsigned long flags ) [virtual, inherited]

As setQueryFlags, except the flags passed as parameters are removed from the existing flags on this object.

Definition at line 272 of file OgreMovableObject.h.

virtual void Ogre::MovableObject::removeVisibilityFlags ( uint32 flags ) [virtual, inherited]

As setVisibilityFlags, except the flags passed as parameters are removed from the existing flags on this object.

Definition at line 300 of file OgreMovableObject.h.
References Ogre::uint32.

void Ogre::MovableObject::setCastShadows ( bool enabled ) [inherited]

Sets whether or not this object will cast shadows.

Remarks:
This setting simply allows you to turn on/off shadows for a given object. An object will not cast shadows unless the scene supports it in any case (see SceneManager::setShadowTechnique), and also the material which is in use must also have shadow casting enabled. By default all entities cast shadows. If, however, for some reason you wish to disable this for a single object then you can do so using this method.

Note:
This method normally refers to objects which block the light, but since Light is also a subclass of MovableObject, in that context it means whether the light causes shadows itself.

Definition at line 337 of file OgreMovableObject.h.

void Ogre::MovableObject::setDefaultQueryFlags ( uint32 flags ) [static, inherited]

Set the default query flags for all future MovableObject instances.

Definition at line 279 of file OgreMovableObject.h.
References Ogre::uint32.

void Ogre::MovableObject::setDefaultVisibilityFlags ( uint32 flags ) [static, inherited]

Set the default visibility flags for all future MovableObject instances.

Definition at line 307 of file OgreMovableObject.h.
References Ogre::uint32.

virtual void Ogre::MovableObject::setQueryFlags ( uint32 flags ) [virtual, inherited]

Sets the query flags for this object.

Remarks:
When performing a scene query, this object will be included or excluded according to flags on the object and flags on the query. This is a bitwise value, so only when a bit on these flags is set, will it be included in a query asking for that flag. The meaning of the bits is application-specific.

Definition at line 264 of file OgreMovableObject.h.
References Ogre::uint32.

virtual void Ogre::MovableObject::setRenderingDistance ( Real dist ) [virtual, inherited]

Sets the distance at which the object is no longer rendered.

Parameters:

dist Distance beyond which the object will not be rendered (the default is 0, which means objects are always rendered).

Definition at line 202 of file OgreMovableObject.h.
References Ogre::Real.

virtual void Ogre::MovableObject::setRenderQueueGroup ( uint8 queueID ) [virtual, inherited]

Sets the render queue group this entity will be rendered through.

Remarks:
Render queues are grouped to allow you to more tightly control the ordering of rendered objects. If you do not call this method, all Entity objects default to the default queue (RenderQueue::getDefaultQueueGroup), which is fine for most objects. You may want to alter this if you want this entity to always appear in front of other objects, e.g. for a 3D menu system or such.

See RenderQueue for more details.

Parameters:

queueID Enumerated value of the queue group to use.

Reimplemented in Ogre::Entity, and Ogre::ParticleSystem.

virtual void Ogre::MovableObject::setUserAny ( const Any & anything ) [virtual, inherited]

Sets any kind of user value on this object.

Remarks:
This method allows you to associate any user value you like with this MovableObject. This can be a pointer back to one of your own classes for instance.

Note:
This value is shared with setUserObject so don't use both!

virtual void Ogre::MovableObject::setUserObject ( UserDefinedObject * obj ) [virtual, inherited]

Call this to associate your own custom user object instance with this MovableObject.

Remarks:
By simply making your game / application object a subclass of UserDefinedObject, you can establish a link between an OGRE instance of MovableObject and your own application classes. Call this method to establish the link.

virtual void Ogre::MovableObject::setVisibilityFlags ( uint32 flags ) [virtual, inherited]

Sets the visiblity flags for this object.

Remarks:
As well as a simple true/false value for visibility (as seen in setVisible), you can also set visiblity flags which when 'and'ed with the SceneManager's visibility mask can also make an object invisible.

virtual void Ogre::MovableObject::setVisible ( bool visible ) [virtual, inherited]

Tells this object whether to be visible or not, if it has a renderable component.

Note:
An alternative approach of making an object invisible is to detach it from it's SceneNode, or to remove the SceneNode entirely. Detaching a node means that structurally the scene graph changes. Once this change has taken place, the objects / nodes that have been removed have less overhead to the visbility detection pass than simply making the object invisible, so if you do this and leave the objects out of the tree for a long time, it's faster. However, the act of detaching / reattaching nodes is in itself more expensive than setting an object visibility flag, since in the latter case structural changes are not made. Therefore, small or frequent visbility changes are best done using this method; large or more longer term changes are best done by detaching.

Reimplemented in Ogre::Light.

virtual void Ogre::ShadowCaster::updateEdgeListLightFacing ( EdgeData * edgeData,

const Vector4 & lightPos

) [protected, virtual, inherited]

Tells the caster to perform the tasks necessary to update the edge data's light listing.
Can be overridden if the subclass needs to do additional things.
Parameters:

edgeData The edge information to update

lightPos 4D vector representing the light, a directional light has w=0.0
