Hello Bertl :)
01:18
aSobhy
what if the first word is corrupted is their a settle time to the value saturate or to ignore the first word ?
01:43
Bertl
what if any word is corrupted?
01:48
aSobhy
it will be ignored if it is a live stream but their is another methods will not ignore and call it again
01:49
Bertl
you cannot 'go back' in a serial stream
01:51
aSobhy
right, so it will be ignored
01:53
aSobhy
sorry for that silly question :/

morning folks!

good day

se6astian
very nice blend4web demo: https://viscircle.de/kamera-konfigurator/?lang=en/#beispiel
15:58
se6astian
if anyone has worked with blend4web before I would love to collaborate to create a 3d axiom camera viewer

nice blend4web demo there, have not used it directly yet, but know blender very well
16:26
BAndiT1983
my guess is, that animation is done using rigging, which is the common way, as shape keys are often not supported, e.g. in unity3d
16:27
BAndiT1983
it was at least the case a while ago

what I want to know is if we can:
16:33
se6astian
1) load external geometry from a file (which format)
16:34
se6astian
2) what requirements there are for UVW unwrapping (if we use a procedural material)?
16:34
se6astian
3) what lighting/shadow capabilities the engine has
16:45

blend4web uses JSON, it can be exported from blender -> https://www.youtube.com/watch?v=c5_KfXlhSu8
16:48
se6astian
I know
16:48
BAndiT1983
https://www.blend4web.com/doc/en/lighting.html
16:48
se6astian
ah thats handy
16:49
se6astian
what I would like to create is a 3d version of something like this: https://lab.apertus.org/M25/123/
16:49
BAndiT1983
thought so already
16:49
BAndiT1983
which materials would be procedural?
16:49
BAndiT1983
metal or something else?
16:50
se6astian
yes an aluminum/metal shader
16:50
se6astian
with blurry reflections optimally
16:50
BAndiT1983
if you do the common unwrapping, then it should work fine, seems like the library is taking care of loading the blender files properly
16:51
BAndiT1983
can also create a test, if you think it would help
16:51
BAndiT1983
blurry reflections can be achieved through some proper spherical backgrund, like HDR and material rougness sit a bit higher
16:52
se6astian
the reflections use an environment map I assume
16:52
se6astian
which would not require the object to be unwrapped at all no?
16:52
BAndiT1983
B4W has very nice docs, this is where every developer can learn
16:52
BAndiT1983
you need unwrapping sometimes, for proper reflection
16:52
BAndiT1983
let me check in blender
16:54
se6astian
the blurry self reflections from https://lab.apertus.org/M25/123/ will be tricky I assume
16:54
shivamgoyal
left the channel
16:54
BAndiT1983
reflection seems to be fine without unwrapping, but i would have to test with our files
16:54
se6astian
unless there are good shaders for that already?
16:54
se6astian
I can export a test file easily
16:54
BAndiT1983
nah, looks not that problematic
16:54
se6astian
let me check the formats onshape can export
16:55
BAndiT1983
can you export this plate, please?
16:55
BAndiT1983
which options do you have?
16:56
se6astian
Parasolid, ACIS, STEP, IGES, SolidWorks, STL, Rhino, Collada
16:56
BAndiT1983
let us try STL, as it is common
16:56
BAndiT1983
collada, if it will not work
16:57
se6astian
on it
16:59
BAndiT1983
what the hell, blend4web CE 1,4GB
16:59
BAndiT1983
have they packed linux distro into it?
17:00
se6astian
https://cloud.gerade.org/index.php/s/sXrSidDtDzib7Ld
17:00
BAndiT1983
thanks, will import it in blender and test if i can adjust its viewport, as b4w is downloading, hope the viewer is included and not only on pro edition
17:01
se6astian
there is CE lite further down:
17:01
se6astian
461 MiB
17:01
BAndiT1983
ah, good to know, but 3mins left, so i will keep on downloading for now
17:02
se6astian
this material might be a good fit: http://elbrujodelatribu.blogspot.com/2013/04/aluminium-material.html

quick test, just used glossy node from blender, just adjusted rougness and add HDR background panorama
17:08
BAndiT1983
rendered it with eevee, which gives me the image on thew fly
17:14
BAndiT1983
se6astian: is b4w downloading for you? it just stops at the end for me
17:14
se6astian
looks good, now the big question is what happens in b4w
17:15
se6astian
I didnt download it
17:15
BAndiT1983
ah, ok
17:15
BAndiT1983
even the plugin is not downloading properly yet
17:16
BAndiT1983
seems like its the problem of their server, as i'Ve had to grab blender 2.79 which downloaded fine from official site
17:16
BAndiT1983
same result in chromium, tried firefox before
17:22
BAndiT1983
download manager helps a lot
17:23
se6astian
great
17:26
se6astian
cooking dinner now

sorry for that , was trying something :P
18:32
Ashu
hello ,Bertl
18:33
Bertl
hey
18:34
Ashu
as we discussed earlier about visualising part in T734
18:35
Ashu
I was looking at axiom alpha there we are using gnuplot
18:36
Bertl
yeah, gnuplot is nice but not a real option for realtime visualization
18:37
Ashu
Hmm , I checked there is a software which uses gnuplot for realtime plotting
18:37
Ashu
*feedgnuplot
18:39
Ashu
https://github.com/XLAR-8/feedgnuplot
18:51
Bertl
I'm sure there are a number of software projects which do this or similar
18:53
Bertl
but the AXIOM is no PC, there is no graphic acceleration and memory access is 'expensive'
18:53
Bertl
so any visualization has to happen at a quite low level and be quite efficient
18:56
Ashu
okay , got it
18:57
Ashu
if that would not work, have you guys already decided something else for visualisation part ?
19:00
Bertl
well, something which can 'render' the output directly into the overlay is probably the best option
19:00
Bertl
for the histogram that should be fairly simple to do, but the other two are probably not so simple
19:09
Ashu
So, any direction to read or look , to get some idea ?
19:12
BAndiT1983|away

19:20
Bertl
any low level embedded drawing library (preferably written in C) should be a good source of inspiration or maybe even suitable for the task
19:21
BAndiT1983
we have wrote down some ideas for a lib
19:21
BAndiT1983
let me check the lab
19:22
BAndiT1983
https://lab.apertus.org/T658
19:22
BAndiT1983
graphicsmagick looked like a good alternative, which is faster and smaller
19:23
BAndiT1983
also inclusion into daemon was considered, so it cound present the data and also send updates over to the web UI
19:23
BAndiT1983
*could
19:32
Ashu
This seems of great help , I will read it in more depth .
19:34
Ashu
and I was trying to figure out areas need optimization in hist.c
19:34
Ashu
there is something bugging me , why have allocated memory to *line as it is not used anywhere ?
19:35
Bertl
URL for the code you are talking about?
19:36
Ashu
and what is center sample area for ?
19:37
Ashu
ohh yes , https://github.com/apertus-open-source-cinema/axiom-beta-firmware/blob/master/software/sensor_tools/hist/hist.c
19:38
Bertl
the *line seems to be a left over from a previous version and can be removed
19:39
Bertl
the center area is a simple hack to reduce the memory access by only sampling the data from a smaller area in the center of the image
19:47
Ashu
okay , understood .
19:49
Ashu
thanku ,Bertl and BAndiT1983 , will be back soon :)
