Hello, I have a question about the glance's reach in a terrain rendering. I'm using DevC++-MingW and dx4devcpp libraries (from www.gamecoding.co.uk, it's DirectX 8).
I have seen that on rendering a big terrain the objects rendered farest from the view point are not displayed (or maybe the objects rendered farest that x pixels from the view point are not diplayed); also I can see that when I move away the view point from the object it is 'undisplayed' gradually, so finally it disappears (it happens moving away over any of the axes).
Let me attach some images to ilustrate that: on the first it's all right, on the second the 'terrace' starts to disappear on the left side, on the third is disappearing from both sides, and in the last one is only a 'triangle'.
The display mode is set to 800x600, format D3DFMT_X8R8G8B8, RefreshRate 75; the backbuffer SwapEffect=D3DSWAPEFFECT_DISCARD, EnableAutoDepthStencil true, AutoDepthStencilFormat=D3DFMT_D16. The terrain is a 50x50 quadrants, each of 40x40, and it is rendered using an index buffer.
My question is: what is that effect? or ¿where can I find info about it and solve that problem? I have downloaded de DirectX9 documentation, done an 'overlook', but I can't find anything about it (I'm not an usually english speaker/reader/writer, so maybe I missed something while reading the documentation).
Thank's in advance
