hi,

Can someone explain what's the differens betwenn Direct3D IM and Direct3D RM.

In Immediate Mode (IM) you have to do everything... plot vertexes, polygons, etc.

In Retained Mode (RM) D3D does it for you (alot of it). You can just load a 3D model directly from a .x file and render it to screen.

D3DIM is better for games, I think, tho I've never used either yet. =)

D3DRM has been dropped my MS, now they only do D3DIM.

D3DRM may seem better, but (I hope) as you all know low-level is better than high-level when it comes to programming. D3DRM has got much less support for new technologies, is slower and is suited mostly for doing 3D applications easily.
