Help... or Kill...

Trying to make some flying camera which can go up to the sky for more then 50000.0f on Y axis... I have a map with iTerrainSceneNode and a iWaterSceneNode... Look like this (dont lough))):

When the camera is close to the ground - everything looks fine:

But when I move upper the following apears:

camPos.Y ~ 2000.0f

camPos.Y ~ 4000.0f

camPos.Y ~ 6000.0f

Shall I kill myself or there can be solution?

UPDATE: Whats wrong with PICTURES???????

Hello
Well the problem with those intersection 'error' is that you are to fare from them and that the scene is too big, too big.
Well I hd some problems like that and I have found out that mostely every video card does that.
Sugestions :
- try scaling down your scene about 10 times or even 100 and see what hapends then

- make a cliner scene I mean don't have poligons that intersect(all grat games use that to make that problem 'go away') I mean perfect alignment of vertexes
and that aslo by testing was done
- don't go so hight

but that is not an practical sugestion though.
- or use fog to mask the effect
- OR USE ALL ABOVE(most recomended)
Good luck

Thanks man...

Yeah - I tried to scale down, everything is perfect but scene becomes SO small that my MD2 models looks like Gulliver in the country of liliputians...

About fog... At the moment I must have camera.FarValue(13000.0f) and fog.NearValue(8000)...

Thats couse Im trying to make fly simulator with the possibility to walk on islands...

Oh...

And another thing:

How is it possible to make clear (not intersected polys) coast-land line?

Think about bsp files
They are made so that no poligons intersects with other.
How to make scenes (meshes) 'clear' :
well use 3DSMax it's the best modeler(for not that advanced users) and it has a function that alignes objects perfect and an other thing there is actulay a modeling concept(expecialy for this porpose).
For one object I sugest using extrude method with slice planes(or tessalate) and it is not recomended to use booleans!!!

I must explain...

I've got low polygon sea-floor plate... half-transparent water plate... 20 heightmaped isles... and BSP level on each isle... there's no problem with heightmap->BPS... the only problem with water->heightmap...

If I remove water plate and the sea-floor plate the map is just perfect on any high...

Do you have any suggestions how to make water level in other way then a additing huge addHillPlaneMesh?
