4 | # COMPONENT: nanovisviewer - 3D volume rendering |
---|
5 | # |
---|
6 | # This widget performs volume rendering on 3D scalar/vector datasets. |
---|
7 | # It connects to the Nanovis server running on a rendering farm, |
---|
8 | # transmits data, and displays the results. |

21 | # FIXME: |
---|
22 | # Need to Add DX readers this client to examine the data before |
---|
23 | # it's sent to the server. This will eliminate 90% of the insanity in |
---|
24 | # computing the limits of all the volumes. I can rip out all the |
---|
25 | # "receive data" "send transfer function" event crap. |
---|
26 | # |
---|
27 | # This means we can compute the transfer function (relative values) and |
---|
28 | # draw the legend min/max values without waiting for the information to |
---|
29 | # come from the server. This will also prevent the flashing that occurs |
---|
30 | # when a new volume is drawn (using the default transfer function) and |
---|
31 | # then when the correct transfer function has been sent and linked to |
---|
32 | # the volume. |
