const Vector3 n2 
)
inline

Adds a triangle to the mesh with reusing already existent vertices via their index.

Parameters
v0The first vertex of the triangle.
n0The normal of the first vertex.
v1The second vertex of the triangle.
n1The normal of the second vertex.
v2The third vertex of the triangle.
n2The normal of the third vertex.

◆ generateBuffers()

size_t Ogre::Volume::MeshBuilder::generateBuffers ( RenderOperation operation)

Generates the vertex- and indexbuffer of this mesh on the given RenderOperation.

Parameters
operationThe RenderOperation for the buffers.
Returns
The amount of generated triangles.

◆ generateWithManualObject()

Entity* Ogre::Volume::MeshBuilder::generateWithManualObject ( SceneManager sceneManager,
const String name,
const String material 
)

Generates an entity via a ManualObject.

Parameters
sceneManagerThe creating sceneManager.
nameThe name for the entity.
materialThe material to use.
Returns
The created entity.

◆ getBoundingBox()

AxisAlignedBox Ogre::Volume::MeshBuilder::getBoundingBox ( void  )

Gets the bounding box of the mesh.

Returns
The bounding box.

◆ executeCallback()

void Ogre::Volume::MeshBuilder::executeCallback ( MeshBuilderCallback callback,
const SimpleRenderable simpleRenderable,
size_t  level,
int  inProcess 
) const

Executes a MeshBuilderCallback on this instance.

Parameters
callbackThe callback to execute.
simpleRenderableContains the SimpleRenderable for which the triangles were built.
levelThe LOD level of this mesh.
inProcessThe amount of other meshes/LOD-Chunks still to be loaded.
