hi all,

i did some games where you are walking around a map.

but the map was always somehow flat + some ups and downs.

but now i started to think about walking on a sphere and my head starts to burn…

i can´t even get the right idea how to start.

for the flat land i normally do:

```
//walking forward
yrotrad = (yrot / 180 * 3.141592654f);
xrotrad = (xrot / 180 * 3.141592654f);
xpos += float(sin(yrotrad))/8 ;
zpos -= float(cos(yrotrad))/8 ;
/// camera looking ahead
if( xrot > 90 ) xrot = 90;
if( xrot < -90 ) xrot = -90;
yrotrad = (yrot / 180 * 3.141592654f);
xrotrad = (xrot / 180 * 3.141592654f);
gluLookAt( xpos, ypos, zpos,
xpos+float(sin(yrotrad)*1.0), ypos-float(sin(xrotrad)*1.0)*yMultiplyer, zpos-float(cos(yrotrad)*1.0),
0.0, 1.0, 0.0 );
```

but how would i need to do this for wlaking on a shpere ??

thanx
