Papervision3d Lag

[Poskusin]

Hey guys.

I'm not sure if this is directly hardware related or not. I've just started playing around with papervision 3d and I threw together this map floor and test sprite to see how it would look. The problem is, whenever I have a large portion or the map in my viewport, IT LAGS LIKE CRAZY. I was just wondering if maybe:

a) my code is horrid
b) my computer is a piece
c) papervision3d is just bad for 3d

I mean the concept is simple, there's nothing fancy going on and I'm only using planes. Maybe it's because I'm using 25x25 of them? I'm new to 3d so any help would be awesome. Is there a better path to use 3D than paper3d? Anyways, here's the code. Thanks guys.

Maybe it's because I'm using 25x25 of them? [/AS]

Definately. That's a ton of planes...

Instead make one big plane and use that. Also, I find the PV3D consumes more cpu cycles when objects get close to a 90degree angle to the camera, your planes are quite close to a 90degree angle to the camera, so that's going to eat a ton of CPU cycles.

Thank you.

So what would be suggested? Create a model of a level in a 3d editor and load it into PV3D? Or is there a way to create one plane and texture it piece by piece with materials?

Would I be best to go find a primer on 3D? or does it change vastly from one language to the next?
