| 16:25.15 | starseeker | brlcad: sure, nuke it - it's in the history if I ever revive that attempt |
| 19:00.52 | brlcad | ``Erik: wasn't that a couple years ago? |
| 19:01.56 | brlcad | the gsoc write-ups looks great, even more detailed than they needed to be |
| 19:02.12 | brlcad | thanks cristina |
| 19:02.40 | brlcad | and to the others, though I don't see them here in the channel at the moment |
| 19:03.10 | brlcad | crdueck: any chance I can get a paragraph or two from you too? |
| 19:03.46 | brlcad | ksenija and laijiren are the other two missing |

| 20:14.43 | brlcad | all the detail from everyone, I'm going to have to change the plans a little bit |
| 20:14.52 | brlcad | these are detailed enough for stand-alone showcasing too |

| 20:48.05 | cristina | brlcad: well, I wrote around 250words, as suggested :) |
| 21:28.32 | ``Erik | brlcad: the discussion was, but the archives were lacking so someone cleaned it up a bit and posted for preservation |
| 22:04.13 | andrei_ | ``Erik, how do you guys manage to draw stuff like this : http://brlcad.org/wiki/Image:Brlcad_gsoc2009_flyer.png ? I ve been trying to get a damn rubik cube to work in c++/freeglut for like 8 hours and it's still broken . |
| 22:44.21 | ``Erik | andrei: looks like a raytrace, a plot2pix and a bunch of gimp or photoshop work... |
| 22:46.02 | ``Erik | and I'm guessing the rubik's cube is an unrelated topic? O.o freeglut would just be the bits to wire the context to the display and input (opposed to glX or wgl or SDL) |
| 22:46.53 | ``Erik | a straight up display issue would be with the opengl not being all correct? |
| 22:47.18 | andrei_ | The issue is that I m not used to "imagine" things in 3d and I make wrong assumptions |
| 22:48.14 | andrei_ | for example, if I needed to solve a rubik cube without any graphical display it would've taken me at most two hours. |
| 22:49.31 | andrei_ | Raytracing is probably much more complicated than the things I am doing at the moment. |
| 22:50.52 | ``Erik | raytracing and rasterization are two different approaches with pros and cons *shrug* raytracing a sphere is trivial, a box is a bit trickier :) |
| 22:51.26 | andrei_ | the only thing I know about the rasterization is that it's the last step the gpu band does ( might have spelling errors) |
| 22:51.53 | ``Erik | the 'redbook' has an appendix that outlines the old approach |
| 22:52.20 | ``Erik | setting up the correct matrices tends to be a tricky subject for new opengl users, are you getting stuff on the screen, just not in the right place? |
| 22:54.13 | andrei_ | I ve been given a framework so I m not using opengl directly. I have a cube drawn from 9 smaller cubes. The cube deforms when I rotate a vertical face and then a horizontal one. |
| 22:55.05 | andrei_ | It happens because I rotate relative to the cube positioned in center of the face. After the first rotation it is no longer there. |
| 22:56.52 | andrei_ | I was saying that it is very difficult to achieve the same result using 3d objects rather than abstract units( array values, for example) |
