### 1.New a renderer and call glsurfaceview.setRenderer


```java

 FilterRenderer mRenderer = new FilterRenderer(glSurfaceView);
 
 //set renderer
 glSurfaceView.setEGLContextClientVersion(2);
 glSurfaceView.setRenderer(mRenderer);
 glSurfaceView.setRenderMode(GLSurfaceView.RENDERMODE_WHEN_DIRTY);
 
 
 //add listener for surfacetexture
 mRenderer.setSurfaceListener(new FilterRenderer.SurfaceListener() {
            @Override
            public void onSurfaceTextureAvailable(SurfaceTexture surface) {

                // use surfacetexture
            }

            @Override
            public void onSurfaceTextureSizeChanged(SurfaceTexture surface, int width, int height) {

            }
        });
   
  
        
```

### 2.Set filter you want

```java

  //New a filter implement you want 
  GLFilter mFilter = new LookupGLFilter(MainActivity.this, R.raw.pic_table);
  
  mRenderer.setFilter(mFilter);
  
  //if you don't want any filter,just call mRenderer.setFilter(null);
 
  

```
