## Member Function Documentation

virtual SJoint* irr::scene::ISkinnedMesh::addJoint | ( | SJoint * | parent = `0` | ) | `[pure virtual]`

Adds a new joint to the mesh, access it as last one.

virtual SSkinMeshBuffer* irr::scene::ISkinnedMesh::addMeshBuffer | ( |  | ) | `[pure virtual]`

Adds a new meshbuffer to the mesh, access it as last one.

virtual SPositionKey* irr::scene::ISkinnedMesh::addPositionKey | ( | SJoint * | joint | ) | `[pure virtual]`

Adds a new position key to the mesh, access it as last one.

virtual SRotationKey* irr::scene::ISkinnedMesh::addRotationKey | ( | SJoint * | joint | ) | `[pure virtual]`

Adds a new rotation key to the mesh, access it as last one.

virtual SScaleKey* irr::scene::ISkinnedMesh::addScaleKey | ( | SJoint * | joint | ) | `[pure virtual]`

Adds a new scale key to the mesh, access it as last one.

virtual SWeight* irr::scene::ISkinnedMesh::addWeight | ( | SJoint * | joint | ) | `[pure virtual]`

Adds a new weight to the mesh, access it as last one.

virtual void irr::scene::ISkinnedMesh::animateMesh | ( | f32 | frame,
|  | f32 | blend |
| ) |  |  | `[pure virtual]`

Animates this mesh's joints based on frame input.

virtual void irr::scene::ISkinnedMesh::convertMeshToTangents | ( |  | ) | `[pure virtual]`

converts the vertex type of all meshbuffers to tangents.

E.g. used for bump mapping.

virtual void irr::scene::ISkinnedMesh::finalize | ( |  | ) | `[pure virtual]`

loaders should call this after populating the mesh

virtual const core::array<SJoint*>& irr::scene::ISkinnedMesh::getAllJoints | ( |  | ) | const`[pure virtual]`

exposed for loaders: joints list

virtual core::array<SJoint*>& irr::scene::ISkinnedMesh::getAllJoints | ( |  | ) | `[pure virtual]`

exposed for loaders: joints list

virtual u32 irr::scene::ISkinnedMesh::getJointCount | ( |  | ) | const`[pure virtual]`

Gets joint count.

Returns:
  Amount of joints in the skeletal animated mesh.

virtual const c8* irr::scene::ISkinnedMesh::getJointName | ( | u32 | number | ) | const`[pure virtual]`

Gets the name of a joint.

Parameters:

  | number,: | Zero based index of joint. The last joint has the number getJointCount()-1;

Returns:
  Name of joint and null if an error happened.

virtual s32 irr::scene::ISkinnedMesh::getJointNumber | ( | const c8 * | name | ) | const`[pure virtual]`

Gets a joint number from its name.

Parameters:

  | name,: | Name of the joint.

Returns:
  Number of the joint or -1 if not found.

virtual core::array<SSkinMeshBuffer*>& irr::scene::ISkinnedMesh::getMeshBuffers | ( |  | ) | `[pure virtual]`

exposed for loaders: to add mesh buffers

virtual bool irr::scene::ISkinnedMesh::isStatic | ( |  | ) | `[pure virtual]`

Check if the mesh is non-animated.

virtual bool irr::scene::ISkinnedMesh::setHardwareSkinning | ( | bool | on | ) | `[pure virtual]`

Allows to enable hardware skinning.

virtual void irr::scene::ISkinnedMesh::setInterpolationMode | ( | E_INTERPOLATION_MODE | mode | ) | `[pure virtual]`

Sets Interpolation Mode.

virtual void irr::scene::ISkinnedMesh::skinMesh | ( |  | ) | `[pure virtual]`

Preforms a software skin on this mesh based of joint positions.

virtual void irr::scene::ISkinnedMesh::updateNormalsWhenAnimating | ( | bool | on | ) | `[pure virtual]`

Update Normals when Animating.

Parameters:

  | on | If false don't animate, which is faster. Else update normals, which allows for proper lighting of animated meshes.

virtual bool irr::scene::ISkinnedMesh::useAnimationFrom | ( | const ISkinnedMesh * | mesh | ) | `[pure virtual]`

Use animation from another mesh.

The animation is linked (not copied) based on joint names so make sure they are unique.

Returns:
  True if all joints in this mesh were matched up (empty names will not be matched, and it's case sensitive). Unmatched joints will not be animated.
