Public Member Functions
	ManualObject (const String &name)
virtual	~ManualObject ()
virtual void	clear (void)
	Completely clear the contents of the object.
virtual void	estimateVertexCount (size_t vcount)
	Estimate the number of vertices ahead of time.
virtual void	estimateIndexCount (size_t icount)
	Estimate the number of vertices ahead of time.
virtual void	begin (const String &materialName, RenderOperation::OperationType opType=RenderOperation::OT_TRIANGLE_LIST)
	Start defining a part of the object.
virtual void	position (const Vector3 &pos)
	Add a vertex position, starting a new vertex at the same time.
virtual void	position (Real x, Real y, Real z)
	Remarks: A vertex position is slightly special among the other vertex data methods like normal() and textureCoord(), since calling it indicates the start of a new vertex. All other vertex data methods you call after this are assumed to be adding more information (like normals or texture coordinates) to the last vertex started with position().
virtual void	normal (const Vector3 &norm)
	Add a vertex normal to the current vertex.
virtual void	normal (Real x, Real y, Real z)
	Remarks: Vertex normals are most often used for dynamic lighting, and their components should be normalised.
virtual void	textureCoord (Real u)
	Add a texture coordinate to the current vertex.
virtual void	textureCoord (Real u, Real v)
	Remarks: You can call this method multiple times between position() calls to add multiple texture coordinates to a vertex. Each one can have between 1 and 3 dimensions, depending on your needs, although 2 is most common. There are several versions of this method for the variations in number of dimensions.
virtual void	textureCoord (Real u, Real v, Real w)
	Remarks: You can call this method multiple times between position() calls to add multiple texture coordinates to a vertex. Each one can have between 1 and 3 dimensions, depending on your needs, although 2 is most common. There are several versions of this method for the variations in number of dimensions.
virtual void	textureCoord (const Vector2 &uv)
	Remarks: You can call this method multiple times between position() calls to add multiple texture coordinates to a vertex. Each one can have between 1 and 3 dimensions, depending on your needs, although 2 is most common. There are several versions of this method for the variations in number of dimensions.
virtual void	textureCoord (const Vector3 &uvw)
	Remarks: You can call this method multiple times between position() calls to add multiple texture coordinates to a vertex.

virtual void	triangle (uint16 i1, uint16 i2, uint16 i3)
	Add a set of 3 vertex indices to construct a triangle; this is a shortcut to calling index() 3 times.
virtual void	quad (uint16 i1, uint16 i2, uint16 i3, uint16 i4)
	Add a set of 4 vertex indices to construct a quad (out of 2 triangles); this is a shortcut to calling index() 6 times, or triangle() twice.

Detailed Description

Class providing a much simplified interface to generating manual objects with custom geometry.

Remarks:: Building one-off geometry objects manually usually requires getting down and dirty with the vertex buffer and vertex declaration API, which some people find a steep learning curve. This class gives you a simpler interface specifically for the purpose of building a one-off 3D object simply and quickly. Note that if you intend to instance your object you will still need to become familiar with the Mesh class.

: This class draws heavily on the interface for OpenGL immediate-mode (glBegin, glVertex, glNormal etc), since this is generally well-liked by people. There are a couple of differences in the results though - internally this class still builds hardware buffers which can be re-used, so you can render the resulting object multiple times without re-issuing all the same commands again. Secondly, the rendering is not immediate, it is still queued just like all OGRE objects. This makes this object more efficient than the equivalent GL immediate-mode commands, so it's feasible to use it for large objects if you really want to.

To construct some geometry with this object:

If you know roughly how many vertices (and indices, if you use them) you're going to submit, call estimateVertexCount and estimateIndexCount. This is not essential but will make the process more efficient by saving memory reallocations.
Call begin() to begin entering data
For each vertex, call position(), normal(), textureCoord(), colour() to define your vertex data. Note that each time you call position() you start a new vertex. Note that the first vertex defines the components of the vertex - you can't add more after that. For example if you didn't call normal() in the first vertex, you cannot call it in any others. You ought to call the same combination of methods per vertex.
If you want to define triangles (or lines/points) by indexing into the vertex list, you can call index() as many times as you need to define them. If you don't do this, the class will assume you want triangles drawn directly as defined by the vertex list, ie non-indexed geometry. Note that stencil shadows are only supported on indexed geometry, and that indexed geometry is a little faster; so you should try to use it.
Call end() to finish entering data.
Optionally repeat the begin-end cycle if you want more geometry using different rendering operation types, or different materials After calling end(), the class will organise the data for that section internally and make it ready to render with. Like any other MovableObject you should attach the object to a SceneNode to make it visible. Other aspects like the relative render order can be controlled using standard MovableObject methods like setRenderQueueGroup.

: Note that like all OGRE geometry, triangles should be specified in anti-clockwise winding order (whether you're doing it with just vertices, or using indexes too). That is to say that the front of the face is the one where the vertices are listed in anti-clockwise order.

virtual void Ogre::ManualObject::begin ( const String & materialName,

RenderOperation::OperationType opType = RenderOperation::OT_TRIANGLE_LIST

materialName The name of the material to render this part of the object with.

opType The type of operation to use to render.

virtual void Ogre::ManualObject::clear ( void ) [virtual]

Completely clear the contents of the object.

Remarks:
This class is not designed for dynamic vertex data, since the translation it has to perform is not suitable for frame-by-frame updates. However if you do want to modify the contents from time to time you can do so by clearing and re-specifying the data.

virtual void Ogre::ManualObject::colour ( Real r,

Real g,

Real b,

Remarks:
After you've finished building this object, you may convert it to a Mesh if you want in order to be able to create many instances of it in the world (via Entity). This is optional, since this instance can be directly attached to a SceneNode itself, but of course only one instance of it can exist that way.

Note:
Only objects which use indexed geometry may be converted to a mesh.

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,

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

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 void Ogre::ManualObject::index ( uint16 idx ) [virtual]

Add a vertex index to construct faces / lines / points via indexing rather than just by a simple list of vertices.

Remarks:
You will have to call this 3 times for each face for a triangle list, or use the alternative 3-parameter version. Other operation types require different numbers of indexes,

See also:
RenderOperation::OperationType.

Note:
32-bit indexes are not supported on all cards which is why this class only allows 16-bit indexes, for simplicity and ease of use.

Parameters:

idx A vertex index from 0 to 65535.

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 true if this object is attached to a SceneNode or TagPoint.

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

Returns true if this object is attached to a SceneNode or TagPoint, and this SceneNode / TagPoint is currently in an active part of the scene graph.

virtual bool Ogre::MovableObject::isVisible ( 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.

virtual void Ogre::ManualObject::normal ( Real x,

Real y,

Real z

) [virtual]

Remarks:
Vertex normals are most often used for dynamic lighting, and their components should be normalised.

virtual void Ogre::ManualObject::normal ( const Vector3 & norm ) [virtual]

Add a vertex normal to the current vertex.

Remarks:
Vertex normals are most often used for dynamic lighting, and their components should be normalised.

virtual void Ogre::ManualObject::position ( Real x,

Real y,

Real z

) [virtual]

Remarks:
A vertex position is slightly special among the other vertex data methods like normal() and textureCoord(), since calling it indicates the start of a new vertex. All other vertex data methods you call after this are assumed to be adding more information (like normals or texture coordinates) to the last vertex started with position().

virtual void Ogre::ManualObject::position ( const Vector3 & pos ) [virtual]

Add a vertex position, starting a new vertex at the same time.

Remarks:
A vertex position is slightly special among the other vertex data methods like normal() and textureCoord(), since calling it indicates the start of a new vertex. All other vertex data methods you call after this are assumed to be adding more information (like normals or texture coordinates) to the last vertex started with position().

virtual void Ogre::ManualObject::quad ( uint16 i1,

uint16 i2,

uint16 i3,

uint16 i4

) [virtual]

Add a set of 4 vertex indices to construct a quad (out of 2 triangles); this is a shortcut to calling index() 6 times, or triangle() twice.
It's only valid for triangle list operations.
Note:
32-bit indexes are not supported on all cards which is why this class only allows 16-bit indexes, for simplicity and ease of use.

Parameters:

i1,i2,i3 3 vertex indices from 0 to 65535 defining a face.

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.

virtual void Ogre::ManualObject::resetTempAreas ( void ) [protected, virtual]

Delete temp buffers and reset init counts.

virtual void Ogre::ManualObject::resizeTempIndexBufferIfNeeded ( size_t numInds ) [protected, virtual]

Resize the temp index buffer?

virtual void Ogre::ManualObject::resizeTempVertexBufferIfNeeded ( size_t numVerts ) [protected, virtual]

Resize the temp vertex buffer?

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!

Definition at line 232 of file OgreMovableObject.h.

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.

Definition at line 216 of file OgreMovableObject.h.

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.

Definition at line 292 of file OgreMovableObject.h.
References Ogre::uint32.

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::ManualObject::textureCoord ( const Vector3 & uvw ) [virtual]

Remarks:
You can call this method multiple times between position() calls to add multiple texture coordinates to a vertex. Each one can have between 1 and 3 dimensions, depending on your needs, although 2 is most common. There are several versions of this method for the variations in number of dimensions.

virtual void Ogre::ManualObject::textureCoord ( const Vector2 & uv ) [virtual]

Remarks:
You can call this method multiple times between position() calls to add multiple texture coordinates to a vertex. Each one can have between 1 and 3 dimensions, depending on your needs, although 2 is most common. There are several versions of this method for the variations in number of dimensions.

virtual void Ogre::ManualObject::textureCoord ( Real u,

Real v,

Real w

) [virtual]

Remarks:

virtual void Ogre::ManualObject::triangle ( uint16 i1,

uint16 i2,

uint16 i3

) [virtual]

Add a set of 3 vertex indices to construct a triangle; this is a shortcut to calling index() 3 times.
It is only valid for triangle lists.
Note:
32-bit indexes are not supported on all cards which is why this class only allows 16-bit indexes, for simplicity and ease of use.

Parameters:

i1,i2,i3 3 vertex indices from 0 to 65535 defining a face.

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
