我正在创建一个我的世界克隆，每当我稍微快一点移动相机时，块之间就会出现很大的撕裂，如下所示：
每个块都是 32x32x32 立方体，并且每种立方体都有一个顶点缓冲区，以防万一。我也在屏幕上绘制 2D 文本，我了解到我必须为每种绘图设置图形设备状态。这是我绘制立方体的方式：
GraphicsDevice.Clear(Color.LightSkyBlue);
#region 3D
// Set the device
device.BlendState = BlendState.Opaque;
device.DepthStencilState = DepthStencilState.Default;
device.RasterizerState = RasterizerState.CullCounterClockwise;
// Go through each shader and draw the cubes of that style
lock (GeneratedChunks)
{
foreach (KeyValuePair<CubeType, BasicEffect> KVP in CubeType_Effect)
{
// Iterate through each technique in this effect
foreach (EffectPass pass in KVP.Value.CurrentTechnique.Passes)
{
// Go through each chunk in our chunk map, and pluck out the cubetype we care about
foreach (Vector3 ChunkKey in GeneratedChunks)
{
if (ChunkMap[ChunkKey].CubeType_TriangleCounts[KVP.Key] > 0)
{
pass.Apply(); // assign it to the video card
KVP.Value.View = camera.ViewMatrix;
KVP.Value.Projection = camera.ProjectionMatrix;
KVP.Value.World = worldMatrix;
device.SetVertexBuffer(ChunkMap[ChunkKey].CubeType_VertexBuffers[KVP.Key]);
device.DrawPrimitives(PrimitiveType.TriangleList, 0, ChunkMap[ChunkKey].CubeType_TriangleCounts[KVP.Key]);
}
}
}
}
}

如果我站着不动，世界看起来还不错。我认为这可能是因为我处于窗口模式，但是当我切换全屏时问题仍然存在。我还假设 XNA 本身是双缓冲的？或者谷歌告诉我的。
