finalize()

void irr::scene::CBatchingMesh::finalize

(

)

first updates the mesh, then drops all source buffers.

once this mesh has been finalized, it cannot be changed again!

getBoundingBox()

const core::aabbox3d< f32 > & irr::scene::CBatchingMesh::getBoundingBox ( ) const

virtual

Returns an axis aligned bounding box of the mesh.

Returns

A bounding box of this mesh is returned.

getMeshBuffer() [1/2]

IMeshBuffer * irr::scene::CBatchingMesh::getMeshBuffer ( const video::SMaterial &  material ) const

virtual

Returns pointer to a mesh buffer which fits a material.

Parameters

material

material to search for

Returns

Returns the pointer to the mesh buffer or NULL if there is no such mesh buffer.

getMeshBuffer() [2/2]

IMeshBuffer * irr::scene::CBatchingMesh::getMeshBuffer ( u32  nr ) const

virtual

Returns pointer to a mesh buffer.

Parameters

nr	Zero based index of the mesh buffer. The maximum value is getMeshBufferCount() - 1;

virtual

Sets a flag of all contained materials to a new value.

Parameters

flag	Flag to set in all materials.
newvalue	New value to set in all materials.
