/** @file Exporter.cpp

|
|
|
Assimp export interface. While it's public interface bears many similarities
|
|
to the import interface (in fact, it is largely symmetric), the internal
|
|
implementations differs a lot. Exporters are considered stateless and are
|
|
simple callbacks which we maintain in a global list along with their
|
|
description strings.
|
|
|
|
Here we implement only the C++ interface (Assimp::Exporter).
