我现在面临这个问题。设法成功地将 fbx 模型加载到手机 7 上。不幸的是，模型在屏幕上似乎显得过大，并且模型的很大一部分离开了屏幕。我怀疑可以对以下代码进行更改，但由于我没有这方面的经验，我现在知道从哪里开始。请指教。或者，如果我最小化 fbx 模型的分辨率/大小会有所帮助吗？谢谢！
// set up the "camera"
Vector3 cameraPosition = new Vector3(1, 1, 0);
Vector3 cameraTarget = Vector3.Zero;
Vector3 cameraUp = Vector3.UnitY;
float nearClippingDistance = 0.1f; // anything closer to cameraPosition than this won't be drawn
float farClippingDistance = 1000f; // anything farther from cameraPosition than this won't be drawn
float fieldOfView = MathHelper.ToRadians(45.0f); // the vertical angle the "camera" can see
float aspectRatio = (float)graphics.PreferredBackBufferWidth / (float)graphics.PreferredBackBufferHeight;
world = Matrix.Identity; // the model's transform; setting it to the identity means it will display at (0,0,0) with no rotation or scaling
view = Matrix.CreateLookAt(cameraPosition, cameraTarget, cameraUp); // put the camera at cameraPosition, looking at cameraTarget, with cameraUp as the vector pointing to the "sky"
projection = Matrix.CreatePerspectiveFieldOfView(fieldOfView, aspectRatio*40, nearClippingDistance, farClippingDistance); // defines the perspective
// set up the alternative cull mode so that our model draws properly
RasterizerState rs = new RasterizerState();
rs.CullMode = CullMode.CullClockwiseFace;
GraphicsDevice.RasterizerState = rs;
