Here is a statics/grass engine that I wrote recently. You use advanced terrain and a static map image to tell where to place the static objects. I've attached the source and media to this post.

Can you post your computer specs and the frames per second that you get? The fps is shown in the top left corner of the window.

Here is a screenshot:


If you have any questions, please post them.
Hope this helps people.

This is very cool.
To get it to work i needed to put

#include "static engine.dba"
#include "rectangle memblocks.dba"

at the start of main.dba.

I get about 80fps, but as high as 150 if i point the camera at the sky. I'm impressed enough to want to shoehorn this stuff into my game.
Dxdia tells me that my computer specs are ~1.7GHz, 512MB RAM. I have a Raedon 9200 which has approx total memory 256MB. Monitor is 85Hz apparently.

Thanks guys! Those fps numbers sound very promising. I get 30-40 fps on my geforce fx 5200. So I guess I should shoot for 30-40 fps on my games to get a good frame rate.

Do you mean an editor to make the static map or the 3d models? If you mean the statics map, then I might make an editor sometime, I just used paint for the one included here.

In my version over "?" in the menu-bar, then "Info". Then a window opens, with a button "Systeminfo". There are many information about the hardware listed..

I've released an update that adds LoD ability, an improved function to see if objects are in the fov, and a wind shader that waves things back and forth.

The lod commands allow you to add as many levels of detail as you want. You just tell one static type to act as the LoD of another. You can chain a whole bunch of types like this.

The improved fov function will allow you to use larger objects without worrying that they'll be culled prematurely.

The wind shader is a cool effect that uses a sine wave and only requires ps 1.1. You can choose which static types you want to apply it to and what limb to apply the shader to.

Just download the demo from the first post.

Runs with ~50 FPS here, and looks very cool. It just looks a bit weird how the grass appears and disappears very near to the camera. A bigger distance and fading would be good (so the grass isn't hidden/shown directly but changes it's transparency/alpha-value over time).
The whole scene reminds me of Guild Wars and Chrome... both very cool games imho.

I'd like to try it with my 8800GTS 640MB, but unfortunately I'm getting an error message that says:

Could not determine parameter type of 'terrain 1' at line 11.

19 - 31 FPS on my:

AMD x86 (1.35 GHz)
512MB RAM (which shouldn't alter FPS rate)
ATI Radeon X1550 Sapphire 512MB
DirectX 9.1c (I don't know how I got that)

Returns higher FPS when looking at the sky, rather than at statics.
