I am working on the same type of program.
What I came up with is I created a mesh and then made copies of it to use as terrain tiles.
Each tile has it's own texture. I also made random textures to use for the tiles. Here's my tile function.
Function CreateTile1() ;Create one tile and return for storage in tile array
Local m=CreateMesh() ;temp mesh
Local ss=CreateSurface(m) ;,b ) ;temp surface
For nx=0 To 27
For nz=0 To 27
V(nx,nz)=AddVertex(ss,nx,0,nz,(nx*0.0352),(nz*0.0352),0 );create all vertices
Next
Next
tt=0
For x=0 To 26 Step 2 ; 0-6 has 16 triangles (16x16=256)
For z=0 To 26 Step 2 ;
t(tt)=AddTriangle( ss,V(x,z),V(x,z+1),V(x+1,z) ) ;
tt=tt+1
t(tt)=AddTriangle( ss,V(x+1,z),V(x,z+1),V(x+1,z+1) )
tt=tt+1
If z< 26 Then t(tt)=AddTriangle( ss,V(x,z+1),V(x,z+2),V(x+1,z+2) )
tt=tt+1
If z< 26 Then t(tt)=AddTriangle( ss,V(x+1,z+2),V(x+1,z+1),V(x,z+1) )
tt=tt+1
If x<26 Then t(tt)=AddTriangle( ss,V(x+1,z),V(x+1,z+1),V(x+2,z+1) )
tt=tt+1
If x<26 Then t(tt)=AddTriangle( ss,V(x+2,z+1),V(x+2,z),V(x+1,z) )
tt=tt+1
If z<26 And x<26 Then t(tt)=AddTriangle( ss,V(x+1,z+1),V(x+1,z+2),V(x+2,z+1) )
tt=tt+1
If z<26 And x<26 Then t(tt)=AddTriangle( ss,V(x+2,z+1),V(x+1,z+2),V(x+2,z+2) )
tt=tt+1
Next
Next
Return m
End Function
This creates a 27x27 unit mesh.
The If .. Then statements are only needed for an odd sized tile.
If you use an even size for your tiles, you can leave them out.
I placed 1 tile at the centre and then placed 8 around it in a ring.
I then scale the mesh x 3 and make a ring around preveous 9 tiles.
I did this for 8 rings each 3 times bigger tiles then the preveous.
I have a viewing area that's 88,000 units out from my centre and it renders at more then 300 fps in debug mode.
This may help you out. I am looking for people that have a similar goal as me to design an awsome outdoor world.
That's why I am passing this on to you.
I may get new ideas from you too.
