Hello. I'm just after a bit of advice really. I need a wobbly landscape that the player moves around on. Camera follows player above their head, typical FPS style.

First - are Matrixes or Terrains considered the best way to accomplish this? Is one faster than the other?

Second - to move the player, is it best to move the ground (and the objects on it) under the player's feet, keeping the camera stationery, to give the illusion of movement; or would it be more efficient to have the player object (and camera) moving around over the ground instead?

Thanks for any advice. Don't want to start off down one road then have to backtrack and rewrite everything. I do this too often!

I recommend NOT using matrices. They're slow and horrible if you want a lot of them. Plus they're not objects so you cannot apply shaders to them or use collision/physics engines on them.

I'd recommend blitzterrain (free or paid for version available) for your terrains and for simple collisions, sparkys collision plugin. (Free!)

As for movement, Depending on world sizes, I'd keep the terrain stationary and move the player. Sparkys has an excellent FPS demo which is a great starting point for anything involving players moving on a terrain.

Thanks for the advice, much appreciated. I'm going to check out BlitzTerrain and Sparky's demo.

Cheers again.
