Detailed Description

Class which holds the geometry of an object.

An IMesh is nothing more than a collection of some mesh buffers (IMeshBuffer). SMesh is a simple implementation of an IMesh. A mesh is usually added to an IMeshSceneNode in order to be rendered.

Member Function Documentation

◆ getBoundingBox()

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

pure virtual

Get an axis aligned bounding box of the mesh.

Returns: Bounding box of this mesh.

Implemented in irr::scene::SAnimatedMesh, and irr::scene::SMesh.

◆ getMeshBuffer() [1/2]

virtual IMeshBuffer* irr::scene::IMesh::getMeshBuffer ( u32 nr ) const

pure virtual

Get pointer to a mesh buffer.

Parameters

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

Returns: Pointer to the mesh buffer or 0 if there is no such mesh buffer.

Implemented in irr::scene::SAnimatedMesh, and irr::scene::SMesh.

◆ getMeshBuffer() [2/2]

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

pure virtual

Get pointer to a mesh buffer which fits a material.

Parameters

material material to search for

Returns: Pointer to the mesh buffer or 0 if there is no such mesh buffer.

Implemented in irr::scene::SAnimatedMesh, and irr::scene::SMesh.

◆ getMeshBufferCount()

virtual u32 irr::scene::IMesh::getMeshBufferCount ( ) const

pure virtual

Get the amount of mesh buffers.

Returns: Amount of mesh buffers (IMeshBuffer) in this mesh.

Implemented in irr::scene::SAnimatedMesh, and irr::scene::SMesh.

◆ getMeshType()

virtual E_ANIMATED_MESH_TYPE irr::scene::IMesh::getMeshType ( ) const

inlinevirtual

Returns the type of the meshes.

This is useful for making a safe downcast. For example, if getMeshType() returns EAMT_MD2 it's safe to cast the IMesh to IAnimatedMeshMD2. Note: It's no longer just about animated meshes, that name has just historical reasons.

Returns: Type of the mesh

Reimplemented in irr::scene::SAnimatedMesh, and irr::scene::IAnimatedMesh.

Definition at line 124 of file IMesh.h.

                 {
                         return EAMT_STATIC;
                 }

◆ setBoundingBox()

virtual void irr::scene::IMesh::setBoundingBox ( const core::aabbox3df & box )

pure virtual

Set user-defined axis aligned bounding box.

Parameters

box	New bounding box to use for the mesh.

Implemented in irr::scene::SAnimatedMesh, and irr::scene::SMesh.

◆ setDirty()

virtual void irr::scene::IMesh::setDirty ( E_BUFFER_TYPE buffer = EBT_VERTEX_AND_INDEX )

pure virtual

Flag the meshbuffer as changed, reloads hardware buffers.

This method has to be called every time the vertices or indices have changed. Otherwise, changes won't be updated on the GPU in the next render cycle.

Implemented in irr::scene::SAnimatedMesh, and irr::scene::SMesh.

◆ setHardwareMappingHint()

virtual void irr::scene::IMesh::setHardwareMappingHint	(	E_HARDWARE_MAPPING	newMappingHint,
		E_BUFFER_TYPE	buffer = `EBT_VERTEX_AND_INDEX`
	)

pure virtual

Set the hardware mapping hint.

This methods allows to define optimization hints for the hardware. This enables, e.g., the use of hardware buffers on platforms that support this feature. This can lead to noticeable performance gains.

Implemented in irr::scene::SAnimatedMesh, and irr::scene::SMesh.

◆ setMaterialFlag()

virtual void irr::scene::IMesh::setMaterialFlag	(	video::E_MATERIAL_FLAG	flag,
		bool	newvalue
	)

pure 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.

Implemented in irr::scene::SAnimatedMesh, and irr::scene::SMesh.
