Detailed Description

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

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 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:

  1. 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.
  2. Call begin() to begin entering data
  3. 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.
  4. 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, i.e. 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.
  5. Call end() to finish entering data.
  6. 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.

You can also use beginUpdate() to alter the geometry later on if you wish. If you do this, you should call setDynamic(true) before your first call to begin(), and also consider using estimateVertexCount() / estimateIndexCount() if your geometry is going to be growing, to avoid buffer recreation during growth.

Note
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.

Member Function Documentation

◆ _releaseManualHardwareResources()

void Ogre::ManualObject::_releaseManualHardwareResources ( )
inlinevirtual

Notifies the movable object that hardware resources were lost.

Remarks
Called automatically by RenderSystem if hardware resources were lost and can not be restored using some internal mechanism. Among affected resources are nested shadow renderables, ManualObjects, etc.

Reimplemented from Ogre::MovableObject.

◆ clear()

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

Completely clear the contents of the object.

Remarks
Clearing the contents of this object and rebuilding from scratch is not the optimal way to manage dynamic vertex data, since the buffers are recreated. If you want to keep the same structure but update the content within that structure, use beginUpdate() instead of clear() begin(). However if you do want to modify the structure from time to time you can do so by clearing and re-specifying the data.

◆ estimateVertexCount()

virtual void Ogre::ManualObject::estimateVertexCount ( size_t  vcount)
virtual

Estimate the number of vertices ahead of time.

Remarks
Calling this helps to avoid memory reallocation when you define vertices. Also very handy when using beginUpdate() to manage dynamic data - you can make the vertex buffers a little larger than their initial needs to allow for growth later with this method.

◆ estimateIndexCount()

virtual void Ogre::ManualObject::estimateIndexCount ( size_t  icount)
virtual

Estimate the number of indices ahead of time.

Remarks
Calling this helps to avoid memory reallocation when you define indices. Also very handy when using beginUpdate() to manage dynamic data - you can make the index buffer a little larger than the initial need to allow for growth later with this method.

◆ begin() [1/2]

virtual void Ogre::ManualObject::begin ( const String materialName,
RenderOperation::OperationType  opType = RenderOperation::OT_TRIANGLE_LIST,
const String groupName = ResourceGroupManager::DEFAULT_RESOURCE_GROUP_NAME 
)
virtual

Start defining a part of the object.

Remarks
Each time you call this method, you start a new section of the object with its own material and potentially its own type of rendering operation (triangles, points or lines for example).
Parameters
materialNameThe name of the material to render this part of the object with.
opTypeThe type of operation to use to render.
groupNameThe resource group of the material to render this part of the object with.

◆ begin() [2/2]

virtual void Ogre::ManualObject::begin ( const MaterialPtr mat,
RenderOperation::OperationType  opType = RenderOperation::OT_TRIANGLE_LIST 
)
virtual

This is an overloaded member function, provided for convenience. It differs from the above function only in what argument(s) it accepts.

Parameters
matThe material to render this part of the object with.
opTypeThe type of operation to use to render.

◆ setBufferUsage()

void Ogre::ManualObject::setBufferUsage ( HardwareBuffer::Usage  usage)
inline

Use before defining geometry to indicate how you intend to update the geometry.

◆ setDynamic()

void Ogre::ManualObject::setDynamic ( bool  dyn)
inline

This is an overloaded member function, provided for convenience. It differs from the above function only in what argument(s) it accepts.

References Ogre::HardwareBuffer::HBU_DYNAMIC_WRITE_ONLY, and Ogre::HardwareBuffer::HBU_STATIC_WRITE_ONLY.

◆ getDynamic()

bool Ogre::ManualObject::getDynamic ( ) const
inline

Gets whether this object is marked as dynamic.

References Ogre::HardwareBuffer::HBU_DYNAMIC.

◆ beginUpdate()

virtual void Ogre::ManualObject::beginUpdate ( size_t  sectionIndex)
virtual

Start the definition of an update to a part of the object.

Remarks
Using this method, you can update an existing section of the object efficiently. You do not have the option of changing the operation type obviously, since it must match the one that was used before.
Note
If your sections are changing size, particularly growing, use estimateVertexCount and estimateIndexCount to pre-size the buffers a little larger than the initial needs to avoid buffer reconstruction.
Parameters
sectionIndexThe index of the section you want to update. The first call to begin() would have created section 0, the second section 1, etc.

◆ position() [1/2]

void Ogre::ManualObject::position ( const Vector3 pos)
inline

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().

◆ normal() [1/2]

void Ogre::ManualObject::normal ( const Vector3 norm)
inline

◆ tangent() [1/2]

void Ogre::ManualObject::tangent ( const Vector3 tan)
inline

Add a vertex tangent to the current vertex.

Remarks
Vertex tangents are most often used for dynamic lighting, and their components should be normalised. Also, using tangent() you enable VES_TANGENT vertex semantic, which is not supported on old non-SM2 cards.

inline

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

It is only valid for triangle lists.

Note
32-bit indexes are not supported on all cards and will only be used when required, if an index is > 65535.
Parameters
i1,i2,i33 vertex indices from 0 to 4294967295 defining a face.

◆ quad()

void Ogre::ManualObject::quad ( uint32  i1,
uint32  i2,
uint32  i3,
uint32  i4 
)
inline

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 and will only be used when required, if an index is > 65535.
Parameters
i1,i2,i3,i44 vertex indices from 0 to 4294967295 defining a quad.

◆ getCurrentVertexCount()

virtual size_t Ogre::ManualObject::getCurrentVertexCount ( ) const
virtual

Get the number of vertices in the section currently being defined (returns 0 if no section is in progress).

◆ getCurrentIndexCount()

virtual size_t Ogre::ManualObject::getCurrentIndexCount ( ) const
virtual

Get the number of indices in the section currently being defined (returns 0 if no section is in progress).

◆ end()

virtual ManualObjectSection* Ogre::ManualObject::end ( void  )
virtual

Finish defining the object and compile the final renderable version.

Note
Will return a pointer to the finished section or NULL if the section was discarded (i.e. has zero vertices/indices).

◆ setMaterialName()

virtual void Ogre::ManualObject::setMaterialName ( size_t  subIndex,
const String name,
const String group = ResourceGroupManager::DEFAULT_RESOURCE_GROUP_NAME 
)
virtual

Alter the material for a subsection of this object after it has been specified.

Remarks
You specify the material to use on a section of this object during the call to begin(), however if you want to change the material afterwards you can do so by calling this method.
Parameters
subIndexThe index of the subsection to alter
nameThe name of the new material to use
groupThe resource group of the new material to use

◆ setMaterial()

virtual void Ogre::ManualObject::setMaterial ( size_t  subIndex,
const MaterialPtr mat 
)
virtual

This is an overloaded member function, provided for convenience. It differs from the above function only in what argument(s) it accepts.

Parameters
subIndexThe index of the subsection to alter
matThe new material to use

◆ convertToMesh()

virtual MeshPtr Ogre::ManualObject::convertToMesh ( const String meshName,
const String groupName = ResourceGroupManager::DEFAULT_RESOURCE_GROUP_NAME 
)
virtual

Convert this object to a Mesh.

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.
Parameters
meshNameThe name to give the mesh
groupNameThe resource group to create the mesh in

◆ setUseIdentityProjection()

void Ogre::ManualObject::setUseIdentityProjection ( bool  useIdentityProjection)

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

Remarks
Usually ManualObjects 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. Normally you don't need to change this. The default is false.

◆ getUseIdentityProjection()

bool Ogre::ManualObject::getUseIdentityProjection ( void  ) const
inline

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

Remarks
Usually ManualObjects 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. Normally you don't need to change this.

◆ setUseIdentityView()

void Ogre::ManualObject::setUseIdentityView ( bool  useIdentityView)

Sets whether or not to use an 'identity' view.

Remarks
Usually ManualObjects 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. Normally you don't need to change this. The default is false.

◆ getUseIdentityView()

bool Ogre::ManualObject::getUseIdentityView ( void  ) const
inline

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

Remarks
Usually ManualObjects 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. Normally you don't need to change this.

◆ setBoundingBox()

void Ogre::ManualObject::setBoundingBox ( const AxisAlignedBox box)
inline

Sets the bounding box.

Remarks
Call this after having finished creating sections to modify the bounding box. E.g. if you're using ManualObject to create 2D overlays you can call things function to set an infinite bounding box so that the object always stays visible when attached.

◆ getSections()

const std::vector<ManualObjectSection*>& Ogre::ManualObject::getSections ( ) const
inline

Gets the list of ManualObjectSection, i.e.

a part of a ManualObject.

◆ getSection()

◆ getNumSections()

unsigned int Ogre::ManualObject::getNumSections ( void  ) const

◆ setKeepDeclarationOrder()

void Ogre::ManualObject::setKeepDeclarationOrder ( bool  keepOrder)
inline

Sets whether or not to keep the original declaration order when queuing the renderables.

Remarks
This overrides the default behavior of the rendering queue, specifically stating the desired order of rendering. Might result in a performance loss, but lets the user to have more direct control when creating geometry through this class.
Parameters
keepOrderWhether to keep the declaration order or not.

◆ getKeepDeclarationOrder()

bool Ogre::ManualObject::getKeepDeclarationOrder ( ) const
inline

Gets whether or not the declaration order is to be kept or not.

Returns
A flag indication if the declaration order will be kept when queuing the renderables.

◆ getMovableType()

const String& Ogre::ManualObject::getMovableType ( void  ) const

◆ _updateRenderQueue()

void Ogre::ManualObject::_updateRenderQueue ( RenderQueue queue)
virtual

Internal method by which the movable object must add Renderable subclass instances to the rendering queue.

Remarks
The engine will call this method when this object is to be rendered. The object must then create one or more Renderable subclass instances which it places on the passed in Queue for rendering.

Implements Ogre::MovableObject.

◆ getEdgeList()

EdgeData* Ogre::ManualObject::getEdgeList ( void  )
overridevirtual

Implement this method to enable stencil shadows.

Implements Ogre::ShadowCaster.

◆ visitRenderables()

void Ogre::ManualObject::visitRenderables ( Renderable::Visitor visitor,
bool  debugRenderables = false 
)
virtual

Method to allow a caller to abstractly iterate over the Renderable instances that this MovableObject will add to the render queue when asked, if any.

Parameters
visitorPointer to a class implementing the Renderable::Visitor interface which will be called back for each Renderable which will be queued. Bear in mind that the state of the Renderable instances may not be finalised depending on when you call this.
debugRenderablesIf false, only regular renderables will be visited (those for normal display). If true, debug renderables will be included too.

Implements Ogre::MovableObject.
