# 你好，我创建了一个平面，并偏移了1000m，视图变换后平面有些抖动，麻烦请您能给个解决方案 代码很简单，我直接铺这里了。期待您的回复。

```
precision highp float;
  attribute vec3 position3DHigh;
  attribute vec3 position3DLow;
  attribute float batchId;
  attribute vec4 position;
  attribute vec3 normal;
  void main() {
      // vec4 viewPosition = czm_translateRelativeToEye(position3DHigh, position3DLow);
      // gl_Position = czm_modelViewProjectionRelativeToEye*viewPosition;
      // 以上方式不抖，但不知道怎么偏移

      vec4 worldPosition = czm_model * position;
      vec3 normalWorld = normalize(mat3(czm_model) * normal);
      worldPosition.xyz += normalWorld * 1005.; // 能偏移，但视图变换会抖，精度不够？
      gl_Position = czm_viewProjection * worldPosition;
      
  }

我会正常偏移了，但纹理坐标标又出现了问题，纹理坐标输出是黑色的，之前用模型到世界坐标，纹理坐标还是正常的` const vs =`  
precision highp float;  
attribute vec3 position3DHigh;  
attribute vec3 position3DLow;  
attribute float batchId;  
attribute vec4 position;  
attribute vec3 normal;  
attribute vec2 st;  
varying vec2 v\_st;  
void main() {  
v\_st = st;  
vec4 pos\_ec = czm\_translateRelativeToEye(position3DHigh, position3DLow);  
vec3 normal\_wc = normalize(mat3(czm\_model) \* normal);  
vec4 normal\_ec = normalize(mat4(czm\_inverseView) \* vec4(normal\_wc,1.));  
pos\_ec.xyz += normal\_ec.xyz \* 1015.;  
gl\_Position = czm\_modelViewProjectionRelativeToEye \* pos\_ec; //投影变换  
}  
`; const fs = `  
varying vec2 v\_st;  
void main()  
{  
gl\_FragColor = vec4(v\_st,0.,1.);  
}
