    <p>Well, I am creating a minecraft terrain thing just for the heck of it. The problem I have is that if you look on a certain angle some faces which are actually behind others are drawn in front of them, thus not showing the actual ones which are there. Like minecraft I have the terrain seperated into regions, and when the vertexbuffer is built, only the "outside" faces are shown. It is also for some reason is not drawing the very top nor the left blocks. In addition to all of these problems faces seem to be overlapping ie (only half of a face can be seen)</p> <p>Here is what it looks like (note I am only drawing the top faces because I have to fix the others up): <a href="http://s1100.photobucket.com/albums/g420/darestium/?action=view&amp;current=minecraftliketerrain.png" rel="nofollow">http://s1100.photobucket.com/albums/g420/darestium/?action=view&amp;current=minecraftliketerrain.png</a></p> <p>I am also drawing all the regions in one go with the following method (i'm using reimer's effect file until I can write my own :):</p> <pre><code>public void Draw(Player player, World world) { effect.CurrentTechnique = effect.Techniques["TexturedNoShading"]; effect.Parameters["xWorld"].SetValue(Matrix.Identity); effect.Parameters["xProjection"].SetValue(player.Camera.ProjectionMatrix); effect.Parameters["xView"].SetValue(player.Camera.ViewMatrix); effect.Parameters["xCamPos"].SetValue(player.Camera.Position); effect.Parameters["xTexture"].SetValue(world.TextureAlias.SheetTexture); effect.Parameters["xCamUp"].SetValue(player.Camera.UpDownRotation); for (int x = 0; x &lt; world.regions.GetLength(0); x++) { for (int y = 0; y &lt; world.regions.GetLength(1); y++) { foreach (EffectPass pass in effect.CurrentTechnique.Passes) { pass.Apply(); Region region = world.regions[x, y]; if (player.Camera.BoundingFrustum.Contains(region.BoundingBox) != ContainmentType.Disjoint) { device.SetVertexBuffer(region.SolidVertexBuffer); //device.Indices = region.SolidIndices; device.DrawPrimitives(PrimitiveType.TriangleList, 0, region.VertexCount); //device.DrawIndexedPrimitives(PrimitiveType.TriangleList, 0, 0, region.VertexCount, 0, region.SolidIndices.IndexCount / 3); } } } } } </code></pre> <p>Help would be much appreciated thanks :)</p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
