An interface for easy manipulation of meshes.

fixing problems with wrong imported or exported meshes quickly after loading. It is not intended for doing mesh modifications and/or animations during runtime.

The function is thread-safe (read: you can optimize several meshes in different threads).
mesh | Source mesh for the operation. |
Clones a static IMesh into a modifiable SMesh.
All meshbuffers in the returned SMesh
are of type SMeshBuffer or SMeshBufferLightMap.

pure virtual |

This is useful if you want to draw tangent space normal
mapped geometry because it calculates the tangent and binormal data which is needed there.
mesh | Input mesh |
recalculateNormals | The normals are recalculated if set, otherwise the original ones are kept. Note that keeping the normals may introduce inaccurate tangents if the normals are very different to those calculated from the faces. |
smooth | The normals/tangents are smoothed across the meshbuffer's faces if this flag is set. |
angleWeighted | Improved smoothing calculation used |
recalculateTangents | Whether are actually calculated, or just the mesh with proper type is created. |

triangles and vice versa.
