If you want to use the whole Blender material/lighting/environment options then you should render it to some common video format, then implement loader for that video format in your code and show frames as sequence of images. While in theory it is possible to parse Blender file and reimplement it's rendering system, it is too much work to do.

If you only need object placements, basic textures, lights and camera movement you may try using some common export format, like FBX. But you still have to find/implement the loader of that specific file format, implement animation system and so on.
