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 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, 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.
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.

: 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 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.

Member Function Documentation

◆ _releaseManualHardwareResources()

void Ogre::v1::ManualObject::_releaseManualHardwareResources ( )

inlineoverridevirtual

Reimplemented from Ogre::MovableObject.

◆ _updateRenderQueue()

void Ogre::v1::ManualObject::_updateRenderQueue	(	RenderQueue *	queue,
		Camera *	camera,
		const Camera *	lodCamera
	)

overridevirtual

Reimplemented from Ogre::MovableObject.

◆ begin()

virtual void Ogre::v1::ManualObject::begin	(	const String &	materialName,
		OperationType	opType = `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

materialName	The name of the material to render this part of the object with.
opType	The type of operation to use to render.

◆ beginUpdate()

virtual void Ogre::v1::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

sectionIndex The index of the section you want to update. The first call to begin() would have created section 0, the second section 1, etc.

◆ clear()

virtual void Ogre::v1::ManualObject::clear ( )

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.

◆ colour() [1/2]

virtual void Ogre::v1::ManualObject::colour ( const ColourValue & col )

virtual

Add a vertex colour to a vertex.

◆ colour() [2/2]

virtual void Ogre::v1::ManualObject::colour	(	Real	r,
		Real	g,
		Real	b,
		Real	a = `1.0f`
	)

virtual

Add a vertex colour to a vertex.

Parameters

r,g,b,a Colour components expressed as floating point numbers from 0-1

◆ convertToMesh()

virtual MeshPtr Ogre::v1::ManualObject::convertToMesh	(	const String &	meshName,
		const String &	groupName = `ResourceGroupManager::DEFAULT_RESOURCE_GROUP_NAME`,
		bool	buildShadowMapBuffers = `true`
	)

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

meshName	The name to give the mesh
groupName	The resource group to create the mesh in
buildShadowMapBuffers	True to create an optimized copy of the vertex buffers for efficient shadow mapping.

◆ end()

virtual ManualObjectSection* Ogre::v1::ManualObject::end ( )

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).

◆ estimateIndexCount()

virtual void Ogre::v1::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.

◆ estimateVertexCount()

virtual void Ogre::v1::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.

◆ getCurrentIndexCount()

virtual size_t Ogre::v1::ManualObject::getCurrentIndexCount ( ) const

virtual

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

◆ getCurrentVertexCount()

virtual size_t Ogre::v1::ManualObject::getCurrentVertexCount ( ) const

virtual

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

◆ getDynamic()

virtual bool Ogre::v1::ManualObject::getDynamic ( ) const

inlinevirtual

Gets whether this object is marked as dynamic.

◆ getEdgeList()

EdgeData* Ogre::v1::ManualObject::getEdgeList ( )

Implement this method to enable stencil shadows.

◆ getKeepDeclarationOrder()

bool Ogre::v1::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::v1::ManualObject::getMovableType ( ) const

overridevirtual

Implements Ogre::MovableObject.

◆ getNumSections()

unsigned int Ogre::v1::ManualObject::getNumSections ( ) const

Retrieves the number of ManualObjectSection objects making up this ManualObject.

◆ getSection()

ManualObjectSection* Ogre::v1::ManualObject::getSection ( unsigned int index ) const

Gets a pointer to a ManualObjectSection, i.e.

a part of a ManualObject.

◆ getUseIdentityProjection()

bool Ogre::v1::ManualObject::getUseIdentityProjection ( ) 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.

See also: ManualObject::setUseIdentityProjection

◆ getUseIdentityView()

bool Ogre::v1::ManualObject::getUseIdentityView ( ) 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.

See also: ManualObject::setUseIdentityView

◆ getWriteOnly()

virtual bool Ogre::v1::ManualObject::getWriteOnly ( ) const

inlinevirtual

Gets wheter this object has geometry buffer marked as write only.

◆ hasEdgeList()

bool Ogre::v1::ManualObject::hasEdgeList ( )

Overridden member from ShadowCaster.

◆ index()

virtual void Ogre::v1::ManualObject::index ( uint32 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: OperationType.

Note: 32-bit indexes are not supported on all cards and will only be used when required, if an index is > 65535.

Parameters

idx	A vertex index from 0 to 4294967295.

◆ normal() [1/2]

virtual void Ogre::v1::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.

◆ normal() [2/2]

virtual void Ogre::v1::ManualObject::normal	(	Real	x,
		Real	y,
		Real	z
	)

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.

◆ position() [1/2]

virtual void Ogre::v1::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().

◆ position() [2/2]

virtual void Ogre::v1::ManualObject::position	(	Real	x,
		Real	y,
		Real	z
	)

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().

◆ quad()

virtual void Ogre::v1::ManualObject::quad	(	uint32	i1,
		uint32	i2,
		uint32	i3,
		uint32	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 and will only be used when required, if an index is > 65535.

Parameters

i1,i2,i3,i4 4 vertex indices from 0 to 4294967295 defining a quad.

◆ setDynamic()

virtual void Ogre::v1::ManualObject::setDynamic ( bool dyn )

inlinevirtual

Use before defining geometry to indicate that you intend to update the geometry regularly and want the internal structure to reflect that.

◆ setKeepDeclarationOrder()

void Ogre::v1::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

keepOrder Whether to keep the declaration order or not.

◆ setMaterialName()

virtual void Ogre::v1::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

subIndex	The index of the subsection to alter
name	The name of the new material to use

◆ setReadable()

virtual void Ogre::v1::ManualObject::setReadable ( bool readable )

inlinevirtual

Use before defining geometry to indicate that you intend to be able to read back from the geometry buffers again down the line (object convertion to v2, physics engine body creation...

◆ setUseIdentityProjection()

void Ogre::v1::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.

◆ setUseIdentityView()

void Ogre::v1::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.

◆ setWriteOnly()

virtual void Ogre::v1::ManualObject::setWriteOnly ( bool writeOnly )

inlinevirtual

Same as setReadable, but with the invese scemantic.

◆ tangent() [1/2]

virtual void Ogre::v1::ManualObject::tangent ( const Vector3 & tan )

virtual

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.

◆ tangent() [2/2]

virtual void Ogre::v1::ManualObject::tangent	(	Real	x,
		Real	y,
		Real	z
	)

virtual

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.
