blitzTag release

Excellent! Sounds good - I’ll try out the suggestions. Thanks for the quick reply!

your welcome. please let me know if it works in the old build

Achim, the older build fixed my issue. Everything is running smoothly now. Thanks a lot.

The link to the component seems to be dead :frowning:
Could you please fix it?

YO!
I got my kinect to work without the shared memory OP. Now I can just point (or hold up my imaginary spray can) and tag. In the BLITZTAG/Kinect, I added a kinect depth top, flip top, chromakeyed(val min/max) my specific distance (still need to link that to the distance slider in the UI), then i threshholded, blured and wired to the blob track TOP. + house cleaning from bypassing the existing nodes!
Contemplating using the kinect chop to extract skeletal tracking location of a hand, perhaps allowing multiple hands/users.

ALSO the link WAS dead, but I found it again @ graffitiresearchlab.de/blitztag/
THANKS

Hey,

Laser recognition:
I used all the avaiable ressources from the project website (Blitztag v09) as well as the recommended Touchdesigner version non-commercial (077 14080), but I can not make blitztag to recognize the laser point (green one). Mouse writing works without hassle…(tested all on different OS and Geforce GC)

  1. Can it be problematic if I use a USB webcam (Logitech)?
  2. Is a special resolution/framerate needed?
  3. Can it only recognize a beam from a determined angle?
  4. Does the overall light needs to be decreased?

Before I calibrate the cam, the 3 screens in the middle show a picture…after calibration…only the left and the middle shows a picture…the right one is just in a flat single color. The very right screen is just red/white (depending on the threshold).
The cam is adjusted as decribed (with the help of the 4 squares)…and in the lower middle small screen I can also see a high contrast picture with the single point in it moving.

As I understand the function…there is a picture frame comarison for changes in the frames.Before I calibrate the cam…some strokes are randomly created when I move the cam (just from anything recognized in the background picture)…after that…nothing happens any more.

Everything seem to run/is calibrated well …it just feels like the change in picture is not recognized…

Any other suggestions what can avoid the operation?

Thanks a lot for a reply here…

Hi everyone, I’m having some trouble with getting blitztag working, I have followed the pseudo manual but I have one issue when I try to calibrate the laser input, I click enable laser input, choose my camera and then click activate calibration. It will allow me then to adjust sliders for threshold etc but as soon as I click calibrate the third camera window from the left goes completely black and after this I can see it is picking up the laser as a moving white dot in the second window but the third window is black and it will not “paint” anything in the projection
Please help, thanks :slight_smile:

Hey… I’ll look into this ASAP.

Are you using the recommended 077 version of touchdesigner?

please try with these versions of touch

derivative.ca/077/downloads/ … .14080.msi
derivative.ca/077/downloads/ … .14080.msi

I have the same problem like Mr_Popolocoism: A flickering black screen in the third preview window. Can anyone help me?

(Yes, i am using the 14080 build of TD 077)

Hi,

is it possible to use a Canon EOS 5D Mark II (DSLR) to capture the laser?

Hi all, I just discovered this wonderful project.
I’m working to export it to TD 0.88.
It is not perfect, but it’s working…
I’d like also to update it to work with GML 2.0 and 3.0
Does enybody is interested to help me in this task?

Revisiting an old thread here, had my eye on this project for years and only just got a windows PC that i could try it out on.

While i couldn’t find a copy of 077 14080 anywhere online, i have managed to get it mostly functional using TD 077 16900.

The only thing that i’m struggling with is:

Multiple strokes when using laser input.
I get 1 stroke when the laser is first picked up by Blitztag but it doesn’t recognise any following strokes from that point.
Reading the discussion it looks like kdayhoff had the same issue and it may have been fixed by the 14080 build? Any idea if this is an issue with the build i am using or is this just Blitztag itself…? Everything else seems to be working fine with this version from what i can tell!

Hope this gets read, i know it is a very old project so i’m chancing it a bit by posting but i thought it was worth an ask if anyone digs this up!
And amazing job on it too! :slight_smile:

Thanks

This is hard for me to debug as I don’t have the Hardware Setup available. Maybe derivative can make that build available again ?

@Simplo did you manage to get it working in 088 ?

I think that version supported drawing in the main viewport with the mouse. do multiple strokes work when using mouse input ?

@Achim thank you for the reply!

Yes multiple strokes work with the mouse input, just seems to be the laser it doesn’t. It picks up the first stroke and i can draw for as long as i like, but if it loses the laser or i switch the laser off and on then i don’t get any following strokes until i have cleared the current tag. The laser shows up in the viewfinders but no strokes appear after the first stroke.

@kdayhoff was it the build causing this issue for you, or something else?

I will see if i can get a copy of that build through derivative or elsewhere, and will update here if I manage to fix it or if the 14080 build does fix things.

Another interesting point is the render resolution of the viewport - the projector output is 1080p which is working as it should, but the viewport in Blitztag seems to be squashed in from each side, as if Blitztag is displaying a 1080 x 1080 viewport even though i am getting a 1920 x 1080 output. Doesn’t affect anything massively as it still works but wondering if this is related to the build i am using too!

Thanks

If it’s not an issue with the build version it could also be that the blob tracker “sees” another bright spot and thinks this is the laser.

There is some setting to lower the overall projection brightness and a threshold to separate the laser from the projector . Maybe try adjusting these

I haven’t opened that project in 7 years , so I’m afraid I don’t remember the usual problems and solutions

@Achim Not to worry, i have played around with the brightness & threshold settings and not had any luck, i think i will put it down to the build as it sounded like the same issue kdayhoff had that was fixed by using the original build!

I figured it was an old project and i’m really grateful you took the time to reply after all this time anyway!

To anyone else reading i will update if i find a fix or can get my hands on the original build version. :slight_smile:

Hi Achim,
hi all!
Yes, I made it work on 088, but it a was a very “forced” version, modified only to fit my needs, I didn’t made an actual full conversion.
But it seems I have been very provident at that time and I saved, in same folder, a TouchDesigner 077.10480 installer if you need it :smiley:
Please contact me for sending.
