Hello, i am pretty much new in DX progamming, but i managed to find a couple of good tutorials on the net that helped me out to understand the basics.
I am using DX with VB to display 3D building models (actually their concrete or steel "skeleton". The problem i have is this:
i am using lit vertices, each vertex is described by 3 numbers- X,Y,Z coordinates plus nx,ny,nz components of the normal vector. Everything works as good as it gets, as far as the camera remains close to the model. When it moves further (i.e. along the negative Z-axis) then some strange black stripes/triangles appear on my surfaces. Kind of the thing you see when you have 2 overlapping surfaces, belonging to the same plane. That is NOT true on my case, as for example the 2 surfaces have a distance of 0.2 meters between them. Could it be when the camera moves too far, this distance of 0.2 is so small that the surfaces are practically overlapping (although the z-buffer should take care of that)?
I don't know what to think... please help!
