Detailed Description

Abstract interface for callbacks used by on-demand meshes.

Member Function Documentation

virtual const ISimple_mesh * mi::neuraylib::IOn_demand_mesh_callback::call ( ) const

pure virtual

Returns the mesh represented by this callback.

The method may return NULL which is treated like an empty mesh.

Note: The callback is required to always return an equivalent mesh. It does not need to be exactly the same instance, but the represented geometry and all properties must be identical. If you want to change the mesh, you need to install a new instance of this callback object via mi::neuraylib::IOn_demand_mesh::set_callback().
