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

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.

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.

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.

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.

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.

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.

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 pltforms that support this feature. This can lead to noticeable performance gains.

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

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.
