When I do the script below, some of the images are rotated 90 degrees from the others -- that is, the correct viewing direction, but just rotated clockwise 90 degrees. Any thoughts why that would be happening?</div><div><br></div><div>Cheers,</div><div><br></div><div>Andrew</div><div><br></div><div>tf=ColorTransferFunction((mi,ma))</div><div>tf.add_layers(6,w=0.02)</div><div>v,c=pf.h.find_max("Density")</div><div>W = 0.01/pf['pc']</div><div>Nvec=512</div><div>for i in range(200):</div><div> dy=4.*math.pi/199.</div><div> theta = i * dy</div><div> yval = math.cos(theta)</div><div> xval = math.sin(theta)</div><div> L=[xval,yval,0.]</div><div> vp=pf.h.volume_rendering(L,W,c,Nvec,tf,whole_box=True)</div><div> vp.ray_cast()</div><div> write_bitmap(vp.image,"VolTest_%03d.png" % i)</div><div><br></div><div>
