Infinite water plane around terrain island

[YouGroove]

My question is how to have some plane water looking infinite from terrain ?

Specially if you fly high or climb some big hill ?

 

How to make it look infinite ? Mesh Z buffer ?

Hide border of water plane with some distant moutains meshes ?

I think you can do this with the skybox can't you? If you have a skybox that has water on the bottom of it that can supplement your actual water plane when viewed from climbing high

[gamecreator]

That sounds like a decent solution except if your water is animated, you would probably see it animate from a distance as well. But the skybox wouldn't move so the edge could probably still be made out. Not sure how obvious it would be.

I think maybe some kind of fog could help with this? I know in WoW you can only see so far before the fog kicks in and starts blurring things out. I'm sure there are other tricks one could use.

Well water is Shader, skybox is not water shader , perhaps something to try.

 

 

Yes Fog seems the simple better way, just make the plane big enought and put some fog for big distance, and some simple islands meshes to break the empty far space.

[DudeAwesome]

just draw what you see if you want it real

 

 

d= distance to horizont

r= radius from planet

h= eyeheight

 

6400KM= earthradius

Okay Dudeawesome

You should bring concrete solution shader or prefab instaed of theory.

 

Seems subtule distant Fog system is the big winner.

[DudeAwesome]

its not hard theory but this is just small math and easy to implement.

easiest solution to to this would be to set the camera range to d if you use first person view. you also can use distance fog. its up to you what you need for you game and how its the best way to implement it. I cant know it.

in le2 you could make the water really deep and it was a good way of stopping your character dropping off the edge of the map. It just looked like the character had drowned.This was much better than having a bunch of unlikely looking mountains around the edge of your map.

This is not a problem of deep water ,the characters will stay on some island, only some perimter in water will be allowed.

I just need the characters to in top of moutain to not view some border corner of the big water plane.

Try this (I've used it in the past):

 

If you don't want to fog out in the distance, create a disc shape for your water plane. The disc should be made of a few concentric rings of polygons. Select the outermost vertices of the disc and set these vertices' alpha to zero (or, if your water plane needs a LOT of verts, or uses tessellation, you can use a texture component that controls the alpha--map accordingly to create the fade). This transparency will allow the water disc to fade gradually into the sky sphere. Obviously, the bottom half of the sky sphere should be painted to look like ocean so the water disc blends to something similar....

 

Note: if you're using a skybox then you'd use a square plane instead of a disc so it fits better.

 

The special need here would be for a shader that allows vertex alpha to be used to control transparency if needed. Also, generally speaking, fogging out the water plane before the edge can be seen is typically cheaper, but not much. The water plane's transparency doesn't need to be sorted since the only thing that draws "behind" it is the skybox (assuming you can control the render order).

I make infinite water on HLSL. On Nuclear Basic http://forums.nuclearglory.com/index.php?tid=4836&tpg=2

 

1. Make object Plane

2. Apply water shader to it

 

in game cycle:

 

Plane position = camera position

Scroll plane texture on shader automatic

 

//vertex shader
v2f v(a2v In)
{
v2f Out = (v2f)0;

float4 Po = float4(In.position.xyz,1);
float3 Pw = mul(Po,world).xyz;
Out.pos = Pw;
Out.eye = viewInv[3].xyz;
Out.position = mul(Po, wvp);


Out.viewpos = Out.position;


//automatic sroll water if player move
Out.uv.xy = (In.texCoord+Pw.xz)*textureScale;
Out.uv.zw = (In.texCoord2+Pw.xz)*textureScale;


return Out;
}

 

 

O! "Water mode: When checked, a water plane will appear everywhere in the scene"
