hi all...

Is it possible to use sprite's for grass in 3d??...

I mean if you look at Deltaforce one or two...

cus if you use plains ig get's to slow...
and some one I know suggested that I should use sprites..
but I can't get a z depth on it...

does any one know any other way to make grass kinda like deltaforce?

thank's //Mathias

Sprites stay flat to the screen, they're 2d and wouldn't work as 3d grass. I think plains would be the way to go but use them sparingly or create a solid block of grass with a scrolling grass texture on the top maybe kinda like in zelda 64. Personally I'd just texture the ground and add a few bushes as plains or something instead of having lots of 3d grass.

Use textured plains instead. Texture the plain with the grass image (grass blades with a black background), SET OBJECT TRANSPARENCY object,1 and possibly rotate the plains to face the viewer.

One word: "Dynamicism"
Now several paragraphs explaining it

How many grass objects on your map to get it nice and dense? 3000, 4000? Way to much to display...

too much to "display", now there's a word... how many are you actually "displaying"? 50, 100? Now that's not too many objects.

So have 50/100 objects, and re-use them based upon their range or whether they are onscreen.

How you go about doing this and organising your data is very much down to your world design, object design, and game structure. Personally I create about 50 'high poly' grasses, and 100 or so low poly ones - and organise my data by region, area, item in a 3 dimensional array so when I check range for a region I dont have to check each grass - just all in that region.
