I can''t deside which style of vertex buffer to use? static or dynamic? I think if there are enough video memory spaces then static vertex buffer will best and fastest? I can create many static vertex buffer to hold different mesh objects rather than dynamic vertex buffer? What are dynamic vertext buffer''s advantage?

The advantage to dynamic vertex buffers is that they are faster to lock and unlock. For a particle engine for example, you''d want a dynamic vertex buffer because you will be locking/unlcoking to modify the positions a lot. Static vb''s would be better for objects which will never move.

Are static vb only suit object which never move? I can use static vb store objects then use matrix transform move them?
I think dynamic vb suit object which will change their form?
