              Thanks for your quick reply!<br>
              <br>
              I need to modify the frustum parameter(modify the 'far'
              value from 1e4 t 1e5) to test the model in 'deprecated'
              mode. The code of 'local(cgl)' mode is located in
              '/.../ext/core/vgl.min.js'. Do you know where is the WebGL
              code of 'deprecated' mode?<br>
              <br>
              Best,<br>

                          Local(VGL) rendering mode in ParaViewWeb has
                          issues with some model files.<br>
                          <br>
                          How to reproduce the issue:<br>
                          open the visualiser, selecte the data file:
                          'can.ext2'.<br>
                          Under 'Remote mode': all is ok, no issue<br>
                          Under 'Local(VGL) mode': if the model is
                          zoomed out to a certain distance, some faces
                          on the model is shaded black.<br>
                          <br>
                          I guees this is caused by the rendering
                          mechanism differences between Paraview and
                          ParaViewWeb . This issue exists in both
                          paraview4.3 & 4.4, anyone knows how to
                          solve it? or any other solutions the get
                          correct rendering results in Local(VGL) mode?
                          Thanks in advance!<br>
