| 3 | Shalini Venkataraman, Luc Renambot |
|---|
| 4 | Tues Sep 23 |
|---|
| 5 | ----------- |
|---|
| 6 | - Use Tab/backspace to cycle across the different geometry |
|---|
| 7 | Mon Sep 22 |
|---|
| 8 | ---------- |
|---|
| 9 | - added anim of volume data |
|---|
| 10 | - the 3rd argument of -v specifies the thumbnail volume, if not there, theres no thumbnail vol to be displayed |
|---|
| 11 | |
|---|
| 12 | Sat Sep 20 |
|---|
| 13 | ---------- |
|---|
| 14 | - added thumbnail for the fullres volume |
|---|
| 15 | - removed dependant texture from the renderer , its in main now |
|---|
| 16 | - add support for anim of isosurface, |
|---|
| 17 | |
|---|
| 18 | Wed/Thus sep 18 |
|---|
| 19 | --------------- |
|---|
| 20 | - Add a pointer to select for the various render objects |
|---|
| 21 | - fixed isosurface bug(GL_NORMALIZE) |
|---|
| 22 | - fixed bugs in the sliceview mapping to volume mapping |
|---|
| 23 | - use the mouse to click a point on the sliceview to move the probe |
|---|
| 24 | |
|---|
| 25 | Sun Sep 14 |
|---|
| 26 | ---------- |
|---|
| 27 | - fixed bug in accesing optistore (bounds for crop should be inclusive) |
|---|
| 28 | - added the 3 sliceviews and the probe to access the volume, isosurface is generated based on the current value in the probe |
|---|
| 29 | - add menu for cut-plane/object/roam/probe |
|---|
| 30 | |
|---|
| 31 | Thur Sep 11 |
|---|
| 32 | ---------- |
|---|
| 33 | - added isosurface and point rendering, these objects are added at the mouse pointer |
|---|
| 34 | - increase/ decrease isovalues |
|---|
| 35 | |
|---|
| 36 | Wed Sep 10 |
|---|
| 37 | ---------- |
|---|
| 38 | - 2d hist is sent to TFUI everytime a new volume is roamed |
|---|
| 39 | |
|---|
| 40 | Mon Sep 8 |
|---|
| 41 | --------- |
|---|
| 42 | - integrated Optistore, if V_NETDATA, files are loaded from Optiserver, else from local file |
|---|
| 43 | - added keys for roaming the volume, to activate roaming press key 'R' |
|---|
| 44 | - volume class has 2 children vFileVolume and vOptiVolume to handle the 2 different cases |
|---|
| 45 | - have a 1d histogram instead of 2d histogram |
|---|
| 46 | |
|---|
| 47 | Sun Sep 7 |
|---|
| 48 | --------- |
|---|
| 49 | - Added mmap instead of reading from file |
|---|
| 50 | |
|---|
| 51 | Thu Sep 4 |
|---|
| 52 | --------- |
|---|
| 53 | - added a save/load for the gradient volumes |
|---|
| 54 | -g to load the gradient file (8bit) |
|---|
| 55 | 'G' key to write the gradient into to a file (8bit) |
|---|
| 56 | - added save/load for the transfer functions from UI |
|---|
| 57 | use a ppm file to store texture as 1xn for the timebeing |
|---|
| 58 | - 'b' key to toggle display of bounding box |
|---|
| 59 | - save/load LUTs from the GUI(very primitive) |
|---|
| 60 | |
|---|
| 61 | Tue Sep 2 |
|---|
| 62 | --------- |
|---|
| 63 | - added QUANTA tcp to transmit transfer functions |
|---|
| 64 | have a shared buffer betwen the TFUI/network thread |
|---|
| 65 | - when a tcp client(tfUI) connects to volvis, send the histogram of the volume to the UI |
|---|
| 66 | |
|---|
| 67 | Thu Aug 28 |
|---|
| 68 | ---------- |
|---|
| 69 | - keyboard rotation for volume/cutplane - done |
|---|
| 70 | - added clipplane |
|---|
| 71 | - reshuffled code |
|---|
| 72 | |
|---|
| 73 | Thu Aug 21 |
|---|
| 74 | ---------- |
|---|
| 75 | - added MPI to distribute the rendering on the tiles - high latency |
|---|
| 76 | Is it possible to decouple the MPI from the display (dont think so) |
|---|
| 77 | - also tried using QUANTA instead of MPI - check for any difference |
|---|
| 78 | Its worse as expected |
|---|
| 79 | - added a QUANTA DB server for the TF to transmit to all tiles |
|---|
| 80 | (change this so that tf only transmits to master and master broadcasts to all slaves) |
|---|
| 81 | |
|---|
| 82 | Thu Aug 14 |
|---|
| 83 | ---------- |
|---|
| 84 | - separate TF/ volvis app |
|---|
| 85 | Flow something like this |
|---|
| 86 | Init |
|---|
| 87 | Volvis -> TFAPP : Histogram of volume data |
|---|
| 88 | Every network loop |
|---|
| 89 | TFAPP -> Volvis : 2d array for the transfer function |
|---|
| 90 | |
|---|
| 91 | Thu Aug 7 |
|---|
| 92 | --------- |
|---|
| 93 | - add the TF widget to the volvis app |
|---|
| 94 | - added histogram plot of the data/gradient |
|---|
| 95 | |
|---|
| 96 | July 31 |
|---|
| 97 | ------- |
|---|
| 98 | - Luc added CG Fragment shader for the transfer functions |
|---|
