Detailed Description

Loads object models provided in the Wavefront .obj format and builds a ICR::TargetObject.

Note that the .obj models need to contain unique vertex normals for each vertex of the mesh, i.e., smoothing groups are not allowed. This class uses libobj-0.1 for reading the .obj files and implements the necessary callbacks. Note that this class is not thread-safe, sice it uses following global variables: ICR::points_buffer (used to temporally store the mesh-vertices read by ICR::ObjectLoader::geometric_vertex_callback), ICR::normals_buffer (used to temporally store the vertex-normals read by ICR::ObjectLoader::vertex_normal_callback), ICR::face_callback_run (used by ICR::ObjectLoader::triangular_face_geometric_vertices_vertex_normals_callback), ICR::callback_obj_ptr (used by ICR::ObjectLoader::triangular_face_geometric_vertices_vertex_normals_callback in order to access the ICR::TargetObject::object_ member variable) and ICR::map_normal2vertex which is necessary to correlate the vertices to their respective normals. In .obj files, this correlation is contained in the facet definition and cannot be known a priori.

Warning:
Callbacks handling .obj files with texture information only comprise a dummy-implementation right now.
