<div>Hello Everyone!</div>
<div> </div>
<div>I have tested the Marching cubes and Raycasting algorithms with series BMP files:</div>
<div> ring1.bmp ring2.bmp....ring9.bmp (8 bit ,428*354)</div>
<div>the first picture is a white ring in the center of the picture with black background</div>
<div>( "ring1.bmp", the other 8 pictures are the same to the first one)</div>
<div> </div>
<div>In the Attachment:</div>
<div>"vtkContourFilter_result.JPG" is the result of surface rendering with vtkContourFilter</div>
<div>"vtkMarchingCubes_result.JPG"is the result of surface rendering with vtkMarchingCubes</div>
<div>"raycasting_result.JPG" is the result of volume rendering with vtkVolumeRayCastCompositeFunction</div>
<div> </div>
<div>the result of surface rendering with vtkContourFilter is right, but the others is not the result It should be.</div>
<div> </div>
<div>I uses the vtkBMPReader to read the BMP files,</div>
<div>It seems that vtk supports BMP file format not very good?</div>
<div>Looking forward to your reply!</div>
<div> </div>
<div>Thanks in advance!</div></div>
