Hi, I would like to ask shall I regard it is different for implementing viewing frustum culling and octree frustum culling?

Frustum culling is the over term which means that you check e.g. points, spheres, boxes against the frustum planes (normally 6) to see whether something is complete out of this convex area. This is the basis technique.
Ocrees will split up something into many bounding boxes and then you test this bounding boxes against the frustum to be able to reject larger parts at once.
Game Tutorials (http://www.gametutorials.com) has a good (?) description of both Frustum culling and it's application to Oct-Trees...
