Grid Cutting in Half-DirectX

I'm trying to cut the grid in half or at least remove faces from it in real time. How to do this, I wonder?

Locking vertex buffers, memset of selected face or vertex to 0, does not work for me. is there someone solution or tutorial on this i really want this feature in my program!

Greetings

Oh, that’s easy. No need to change the grid. D3D can already do it for you!

Set the plane of the clip with IDirect3DDevice9::SetClipPlane, then enable the plane with D3DRS_CLIPPLANEENABLErenderstate. You can even set multiple clip planes at the same time if you want ..

msdn-entry: http://doc.51windows.net/Directx9_SDK/?url=/directx9_sdk/graphics/reference/d3d/interfaces/idirect3ddevice9/setclipplane.htm

Google "D3D SetClipPlane", , .

You say setting the vertex to 0 does not work. How does it not work?

If you set the position of all the vertices of the triangle to (0.0, 0.0, 0.0), then the resulting triangle will have a zero size and should not be drawn. Just make sure you can set it to off screen instead of zero.
