Hello Bertl :)
02:18
aSobhy
what if the first word is corrupted is their a settle time to the value saturate or to ignore the first word ?
02:43
Bertl
what if any word is corrupted?
02:48
aSobhy
it will be ignored if it is a live stream but their is another methods will not ignore and call it again
02:49
Bertl
you cannot 'go back' in a serial stream
02:51
aSobhy
right, so it will be ignored
02:53
aSobhy
sorry for that silly question :/

morning folks!

good day

se6astian
very nice blend4web demo: https://viscircle.de/kamera-konfigurator/?lang=en/#beispiel
16:58
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
17:26
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
17:27
BAndiT1983
it was at least the case a while ago

what I want to know is if we can:
17:33
se6astian
1) load external geometry from a file (which format)
17:34
se6astian
2) what requirements there are for UVW unwrapping (if we use a procedural material)?
17:34
se6astian
3) what lighting/shadow capabilities the engine has
17:45

blend4web uses JSON, it can be exported from blender -> https://www.youtube.com/watch?v=c5_KfXlhSu8
17:48
se6astian
I know
17:48
BAndiT1983
https://www.blend4web.com/doc/en/lighting.html
17:48
se6astian
ah thats handy
17:49
se6astian
what I would like to create is a 3d version of something like this: https://lab.apertus.org/M25/123/
17:49
BAndiT1983
thought so already
17:49
BAndiT1983
which materials would be procedural?
17:49
BAndiT1983
metal or something else?
17:50
se6astian
yes an aluminum/metal shader
17:50
se6astian
with blurry reflections optimally
17:50
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
17:51
BAndiT1983
can also create a test, if you think it would help
17:51
BAndiT1983
blurry reflections can be achieved through some proper spherical backgrund, like HDR and material rougness sit a bit higher
17:52
se6astian
the reflections use an environment map I assume
17:52
se6astian
which would not require the object to be unwrapped at all no?
17:52
BAndiT1983
B4W has very nice docs, this is where every developer can learn
17:52
BAndiT1983
you need unwrapping sometimes, for proper reflection
17:52
BAndiT1983
let me check in blender
17:54
se6astian
the blurry self reflections from https://lab.apertus.org/M25/123/ will be tricky I assume
17:54
shivamgoyal
left the channel
17:54
BAndiT1983
reflection seems to be fine without unwrapping, but i would have to test with our files
17:54
se6astian
unless there are good shaders for that already?
17:54
se6astian
I can export a test file easily
17:54
BAndiT1983
nah, looks not that problematic
17:54
se6astian
let me check the formats onshape can export
17:55
BAndiT1983
can you export this plate, please?
17:55
BAndiT1983
which options do you have?
17:56
se6astian
Parasolid, ACIS, STEP, IGES, SolidWorks, STL, Rhino, Collada
17:56
BAndiT1983
let us try STL, as it is common
17:56
BAndiT1983
collada, if it will not work
17:57
se6astian
on it
17:59
BAndiT1983
what the hell, blend4web CE 1,4GB
17:59
BAndiT1983
have they packed linux distro into it?
18:00
se6astian
https://cloud.gerade.org/index.php/s/sXrSidDtDzib7Ld
18:00
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
18:01
se6astian
there is CE lite further down:
18:01
se6astian
461 MiB
18:01
BAndiT1983
ah, good to know, but 3mins left, so i will keep on downloading for now
18:02
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
18:08
BAndiT1983
rendered it with eevee, which gives me the image on thew fly
18:14
BAndiT1983
se6astian: is b4w downloading for you? it just stops at the end for me
18:14
se6astian
looks good, now the big question is what happens in b4w
18:15
se6astian
I didnt download it
18:15
BAndiT1983
ah, ok
18:15
BAndiT1983
even the plugin is not downloading properly yet
18:16
BAndiT1983
seems like its the problem of their server, as i'Ve had to grab blender 2.79 which downloaded fine from official site
18:16
BAndiT1983
same result in chromium, tried firefox before
18:22
BAndiT1983
download manager helps a lot
18:23
se6astian
great
18:26
se6astian
cooking dinner now

sorry for that , was trying something :P
19:32
Ashu
hello ,Bertl
19:33
Bertl
hey
19:34
Ashu
as we discussed earlier about visualising part in T734
19:35
Ashu
I was looking at axiom alpha there we are using gnuplot
19:36
Bertl
yeah, gnuplot is nice but not a real option for realtime visualization
19:37
Ashu
Hmm , I checked there is a software which uses gnuplot for realtime plotting
19:37
Ashu
*feedgnuplot
19:39
Ashu
https://github.com/XLAR-8/feedgnuplot
19:51
Bertl
I'm sure there are a number of software projects which do this or similar
19:53
Bertl
but the AXIOM is no PC, there is no graphic acceleration and memory access is 'expensive'
19:53
Bertl
so any visualization has to happen at a quite low level and be quite efficient
19:56
Ashu
okay , got it
19:57
Ashu
if that would not work, have you guys already decided something else for visualisation part ?
20:00
Bertl
well, something which can 'render' the output directly into the overlay is probably the best option
20:00
Bertl
for the histogram that should be fairly simple to do, but the other two are probably not so simple
20:09
Ashu
So, any direction to read or look , to get some idea ?
20:12
BAndiT1983|away

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